    Question about black jack what if the dealer sees the player has over 21 which was the case in my situation and I had 15 and I hit and got an ace and i stayed. Is it the same???

    • The dealer cannot vary strategy. He hits until he has 17 or higher, and then stands. (The only exception is that many casinos have the dealer hit a soft 17 as well.)

    • Joge replied:

      Do not understand your question. You stated that you had over 21 and then you said “I had 15 and hit and got an ace”. So what is it you had over 21 or 16?

    • Anonymous replied:

      no, if the player has over 21 he/she has busted their hand resulting in a loss. The dealer must pick up ones chip if they bust (making over 21). In your case hitting 15 and catching an ace gives you 16 which is not over 21. The goal playing blackjack is to not bust your hand but to get close to 21 as possible. Your odds on busting 16 is greater as you only have 16% chance of catching your cards. This also depends on how many high cards have been played. The more high cards played makes your odds better of making a better. 16 in blackjack in usually a surrender hand but some casinos don’t allow surrender. In this case your better bet is to stay or hit.

        The goal in Blackjack is to beat the Dealer, not to get as close to 21 as you can.

    I am surprised at so many comments that sound so professional, but how naive so many players are. When your gambling no matter if you count cards or use whatever strategy makes you comfortable IT’S GAMBLING! The odds are against you from the start and yes you can practice and count cards all you like, but lady luck always, always wins. Very few are able to make a living gambling it’s just for fun don’t take the game or yourself so serious it’s a waste of time.

    As good as you think this trainer game is and it is a good one there are still many flaws in it. I have lost more on this trainer than in real life. So take and use it for what it is worth, fun.

    My best advice to those who are new to all this is to know when to walk away no matter if your winning and especially when your losing. The next time you venture to your local casino watch the people when playing you will be amazed at what you see. I see so many people sit down to play out of desperation and within minutes lose everything. If you feel desperate don’t play, you will lose and don’t take it out on the dealer it’s not their fault. The house has every right to win just like you do.

    • Anonymous replied:

      If you play long enough the chance of you losing actually becomes less likely than you getting hit by a car or dying on your way to the casino. If you have an advantage, lets say 1% and you were to play 100 thousand hands the probability of you ending up behind is probably less than 1/100,000. That’s a conservative number as well, very conservative. Doesn’t sound like gambling to me.

I as well only went to max bet 225. but in 1 shoe still had a profit of over 1012.5. heres why this data is garbage and its because I won more hands then I lost. what the most important is losing more hands then winning but in set period of time before even raising. I as well had a few blackjacks and the dealer had some blackjacks. blackjacks are theoretically 1/21 hands

        You played 49 hands. Like you said “this data is garbage…” a sample size so small is virtually useless in determining anything. I don’t even know why you posted after only playing 49 hands.

        • Anonymous replied:

          this data is actually not garbage and important data and I will tell you why. blackjack is a negative expectation game. you are going to lose money in the long run. the only edge one can have is counting cards. even then edge is maybe 1-2% overall and the play differs from basic strategy. so therefore one will make no money flat betting period unless they just happen to win more hands then they lose and they as well win double downs. it could go just as much the other direction and basically will be

        • Anonymous replied:

          so it takes overall about 20,000 hands to have any sort of data that is relatively average of what your mathematical expectation should be if you were to card count with an advantage. so I played 1 shoe and lost -1100. I flat betted 100%. I won 14 hands and lost 33. my winning % was 28 which is below average expectation. I as well lost my double downs so that is why I was down so much money just on a short sample

  • Anonymous said:

    I am nobody in the gambling the world and seen as a fool but under new supervision I have decided to put more research and depth into blackjack. Now I have so much negative experience putting my money on the tables and watching it exchanged for plastic cheques. Seeing my pile grow from its existing and watching it dwindle upon consecutive losses. What I do have to offer is some data and thoughts to think about for anyone who choses to read my comment. If this program is as similar as it is in the real casino could it actually be possible to win lots of money??? I am always under the suspicion that casinos can cheat and basically get away with it. I am not saying they do and if they were the only culprit is the computers running that shuffle the cards in such an order that does not always seem so random due to the natural variance in the game. I for a lot of time was against basic strategy but at same time maybe I did not know it well enough to be able to say such crazy things.

    I played 151 hands on this simulator. profit +6100. now I won 66hands and lost 75. so win% was 44. the natural odds of this game with perfect basic strategy is .5 basically in favor of the house. now ask yourself how did I make so much money??? did I count and bet accordingly? I actually did nothing of any sort. I did something a lot more interesting. I some what of what bet progressively upon wins and losses but only went up in increments of 25. I played perfect basic strategy. when I won a couple of hands I increased my bet 25. when I lost say 4 in a row I increased my bet 25 until getting back up to what I was down etc. then when I felt it was smart to just drop down to base I did so basically. I did this over and over again regardless of win or loss streak. if your playing a game with natural set odds this may be a way to just overcome it because you get the bonus of double downs and blackjacks. you as well get the security when you surrender. this way of playing blackjack can really only be played at card rooms and even then the need to offer 3/2 on bj because at indian casinos you do not get that surrender value

Also, the rules are 6D No insurance( It won’t let me. It’s a bug. I would take insurance at a tc of +3 of course) DAS allowed, can’t re splitt aces, late surrender allowed, dealer hits soft 17.
    The big problem I have with the game is that it doesn’t let you take insurance and the penetration is too good. They shuffle when 52 cards are left. How would my win rate be influenced if the deck was shuffled when it reaches 2 decks?

    • Author Ken Smith replied:

      That spread is definitely sufficient to beat this game. In fact, I would guess that your expected win is probably a little more than $2000 over the hands you have played, assuming a win rate of around one big bet per 60 or so hands. Cutting the penetration by a deck would cut your win rate quite a bit, perhaps as much as 50%. I no longer have a copy of Blackjack Attack handy to look up the effect. That’s the easiest way to answer your question without a simulation.

    • Richard replied:

      I don’t have a problem taking insurance. I don’t select the surrender option since the casinos I go to don’t offer it, but I doubt that difference affects the insurance option. If you want insurance, you put an insurance bet in its bet circle before you click on the continue arrow.
      On the other hand, the casino I go to most often puts the yellow “end of shoe” card about a deck away from the last card in the shoe, so I’m happy with the present operation of the program for a 6 deck shoe with regard to penetration.

      You don’t say what your minimum bet is. Is it $5? If so, you are doing very good. if its $10 or $15, your performance is less impressive. But it would be best to make a judgement after more hands have been played, such as 10K to 20K.

  • Jerry said:

    I am new to this Blackjack world, but have played around the world. Right now I live in Germany so I have many casinos in many countries to play. I for some lucky reason win 99% of the time and have never gone home a loser. The casinos in Europe they use the same basic rules though they are smaller compared to U.S. casinos there is a much higher standard of customer requirements such as dress codes. Reminds me of the old days when people dressed up or like a James Bond movie, really cool to see. Anyway I use a couple of trainer games and you must keep in mind these are just helpful games and anyone who thinks they can remember every rule or option to play should remember rules are meant to be broken and are not always correct. Use them as a simple guide not an almighty answer to walking out a winner. Many times I have gone against the recommendations of the game trainer and have won and if I would have followed the advice of the trainer I would have lost. Point being don’t always follow the rule book. So far this trainer game is as close to the real action as it gets, but like others have pointed out it has flaws that are not realistic. The house has the same rights to win as the player does. Go with your gut feelings and know when to walk away. I use these game trainers for basic learning and just to enjoyment. Good luck to all

    • small potatoes replied:

      I agree, I’ve found playing short rounds, betting to make up for losses and stopping after the winning streak of that session leaves me ahead every time and usual with a small decent haul of sometimes 200 to 300 dollars over the course of an hour. If i had 10’s of thousands of dollars to blow could see that small haul exponentially being impressive, but in reality with a small gambling egg and playing perfectly with all the tiny bonuses in your favor your winnings are equivalent to an hourly mediocre job through the course of a day. The biggest rule I feel that doesn’t work and I ignore but statistically has the law of probability in its favor is holding on 12 to 16 hoping the dealer breaks. Mathematically its theory is probably good on paper but in reality the dealer mostly always comes out ahead.

    I forgot to mention I have noticed on a second hit it sends two cards not one, The game also freezes up and at times gets really slow after so many hands.

    I have enjoyed your Blackjack Trainer and I have learned enough to say it has helped me become a better player.You probably already know this, but as good as the Trainer is, it has a few fawls. Such as when a high card appears just about every time like clockwork it equals 20. Also, I know it’s just a game, but there are many repetitious scenarios that happen. This makes the Trainer seem to have somewhat unrealistic outcomes. I have been playing for sometime and I am not a kid and not a pro, but I can see the Trainer has certain outcomes that are not true to life. I would like your game even more if you just made it a little better.

    Sorry for posting twice, but I think it would be very cool if your trainer didn’t play just by basic strategy for the game you’re playing but it also included all of the basic strategy deviations for the card counting system of the player’s choice ( Hi-lo first because it’s what most people use) when it corrects your play. I would like this because I was playing the App and stayed on 16 vs a dealer 10 in a high true count and it said my play was wrong. I think this would be a cool addition. Another cool thing would be allowing the player to choose how much penetration the game has. Thank you for listening!

  • I haven’t played the trainer in some time, but a few days ago I decided to sharpen up a little. I noticed the trainer looked different and saw that it
    had been updated. Okay so far, then when I hit a blackjack with $5.00 bet I noticed that the payoff was not correct for a 3:2 game. I then did
    some experiments and found that with an odd amount bet like $5.00, $15.00, $25.00 etc, it was rounding the payoff up to the next dollar.
    Betting $10.00, $20.00, $30.00 pays correctly. I know “Picky, Picky” for a trainer, but I am that way.

  • old version of trainer, quick play, double on 9,10,11, no double after split blackajack pay for 5 is 2,5 not 7,5.

    • No, you are likely being confused by the way it pays the bet and then rebets the same amount. If you aren’t watching the entire sequence, it seems like the wrong amount is won. If you’ll check your balance before and after the hand, you’ll see that it works correctly.

  • MT1716 said:

    This new version has bugs. It will not allow you to “play out” a split hand. Playing 6D, H17, LS. Once you split and hit/stand on first split hand, the program goes to the dealer to play out the hand before the player has a chance to play out his second hand

  • george v. hillstead said:

    george here again
    on your new version chart with some hands to do double or stand how to decide which way to go on these hands
    like on a-8 if i double i am wrong your chart says either d or s
    still like playing have knot won big but have not lost any sense using basic stragity

    • “Ds” means Double if allowed, else stand. So with (Ace,7) vs a dealer 5, you would double. With (3,4,Ace) you would stand, because doubling is not allowed after you hit.

  • Same situation on the I-pad version and the I-Mac desktop version, inability to hit the second hand after splitting..

  • Love the strategy trainer, but recently I’ve been experiencing a few bugs during play. Sometimes when I split aces I only receive one card on the first ace and no card on the second ace. Sometimes insurance is not offered on a dealer’s ace. Sometimes I’m not able to double. I’m selecting the same rules every time (2d, H17, das, ns, insurance offered). Just wondering if anyone else is getting errors such as these. Thanks.

  • luis beckert said:

    “The effect of surrender for an accurate basic strategy player is to reduce the house edge by somewhere between 0.07% and 0.09% depending on the other rules of the game. If you are a $10 bettor, you should save about 50 cents an hour over the long run. While this improvement is small, every little bit helps. For a card counter, surrender is considerably more valuable for several reasons.”

    What is the percentage of reduction if I am a card counter?

    • The amount of benefit surrender provides for a counter depends on almost everything that can change in the game, penetration, bet spread, etc. There is no convenient one-size-fits-all answer, and I don’t have an estimate at hand. If you need an answer, get some software to check your specific conditions.

    8 decks;
    Dealer stands on soft 17;
    Double any two cards;
    Double after split aloowed;
    Late surrender;
    dealer peeks (US style)
    75% penetration – stop the card 104;


    + 16600.00 betting 100;
    -740.00 The betting 5.

    What would be the result estimated for a real game in this style?


    • I recommend posting this question on the newly re-opened blackjack forums to see if anyone can run a simulation for you with these conditions and betting strategy. I would have to do the same to answer your question, and I’m currently enjoying vacation in Australia instead. 🙂

    • Yes. Just don’t make the mistake of thinking that 10 or 20 hours of experience is very useful in understanding the ups and downs of the game. In the short run, if you are lucky you will win. If you are unlucky you will lose. But you always have the best chance by playing correctly.

  • Sorry, for the confusing post above, it’s me – Ive been practicing playing the game (SD) and using the “The Blackjack Strategy Trainer”, while counting with the KO for SD. Again, I am sure about my counting and the only thing would be a shallow penetration or software that does not use randomly a full deck of cards. Or where am I wrong?

    • You would only expect to reach the exact expected end count if you saw every card in the deck. The trainer mimics what you will see in a real casino, shuffling after the end of the hand where the 35th card is dealt (in the single deck game). The deck(s) are normal, and randomly shuffled.

  • Very strange, I’ve been practicing playing the game and counting using KO for SD. Never came to the endl count of +4., always “0”. Is that because of penetration or ???

  • Dominic said:

    I really enjoy your practice platform. I was wondering, can we play online and make money or should we avoid that and only play in casinos ?

    • Card counting is not much of an option online, although the possibility does exist in the live-dealer games that a few places offer. Even there, the penetration is poor, usually 50% or worse of an 8-deck shoe. The bonuses and promotions can also be profitable sometimes, but these days it is tough to get an actual positive play at online casinos. If you’re a recreational player on the other hand, the games online often have better rules than their land-based competition. So it really depends on what you want from the game.

    • Hopefully. Development of the new version has been at a standstill while I was in a months-long process of getting rid of 80% of my accumulated stuff and moving to a new state. All set now, and back to work. I hope to have something ready to install this fall, although there’s still a lot of work to do.

        Will you post something in this section when the new version is out? I want to wait and get the latest. In the mean time what book or video do you recommend on winning at blackjack? I have only played about 5 times (not counting cards) at the casinos on the 21 plus 3 card tables and have had some decent luck, especially the 3 card bet and would like to learn a bit more about that betting too. Thanks for your practice game, it has been helpful. I tend to go against the grain and do not draw to anything above 14 even when the dealer has a high card and have not done bad. My thoughts are to make the dealer beat me not me busting and beating myself.

        • Things can certainly change quickly. BlackjackInfo has a new owner who took over this month. I know the new team has some excellent resources available for blackjack trainer software. I expect they will be rolling out enhancements pretty quickly, but I’m not involved in that process now.

          You mention wanting to “wait and get the latest”. If you are referring to the other product on this page, Casino Verite is not involved in these changes, and the latest version is available as always at the provided Amazon links.

          Now, on to your final comments… “Going against the grain” can be a very expensive plan. Like any strategy, it can certainly work on any given hand. But I strongly encourage you to learn the correct strategy for the game, and stick to it. Standing with stiff hands against strong dealer upcards does indeed keep you from busting, but you will lose a lot more money in the long run by playing this way.

  • Clay Marion said:

    Going to Vegas in Sept. I have basic strategy down. I need a counting system that I can manage and Hi/Lo isn’t it. I’ve tried 5/Ace. I’m interested in your program but honestly, I REALLY need to know what the most common table rules are for 5/10 min. tables before I invest in another program.

    • Author Ken Smith replied:

      If you are going to just play basic strategy, you can find $5/$10 tables in lots of places with continuous shuffle machines. If you plan to count, you will need to look a lot harder to find decent regular shuffled games at that level. The first thing to check is make sure that blackjack pays 3:2, not 6:5. Check TI for some decent low-limit blackjack tables, or look downtown. The rules are generally going to be 6 deck or 8 deck, dealer hits soft 17, no surrender.

    I’ve playing for 50 years and the house is supposed to win otherwise it wouldn’t be in a casino.

    • Author Ken Smith replied:

      Yes, you are right that Flash is dying. My development of the new mobile-friendly HTML5 version has been stalled a bit while my family prepares to move this summer. After that I’ll be back on the job of replacing the current trainer with a new non-Flash version with tons of new features.

      And yes, I get about an equal number of complaints about the game being rigged to be too easy and too hard. Players who are new to the game just don’t realize how long a lucky or unlucky streak can last. 🙂

    Ken, I just jumped on the trainer after a few months absence. Started reading the comments and noticed that you will be launching a revised version. Any idea of the approximate launch date? Looking forward to the new version. Thanks again for a great strategy trainer!

    • Author Ken Smith replied:

      I was originally targeting June for a launch, but I’ve had a major life change interrupt development. I’m preparing to move my family from Mississippi to Texas, and that stopped development in its tracks over a month ago. I will resume development in August, so I now expect a launch in the fall at the earliest. So, it’s a long wait, but I think worth it.

  • Scott said:

    Hi Ken,
    Why does it seems that I am very successful on your trainer, yet have a very difficult time winning on the wizard’s? If both are using RNG’s should they not be approximately the same. Assuming the same rules, BS, and betting pattern?

    • Author Ken Smith replied:

      I can’t wait until I launch the new version of the trainer. If prior history is repeated, I will be inundated with emails asking why I made the game so much harder to beat, along with an equal number asking why I made it so much easier to beat!

  • hello,
    i have a question.
    when I play how Blackjack Strategy Trainer I win about 80%
    but in real play with the same rule and strategy I lose.
    Can you explain?

      • Sam replied:

        I played about 100 time and I win more than 80% ,
        This is not a luck.
        What algorithm is used for card shuffling?
        I think the trainer play along me.

        • Author Ken Smith replied:

          The trainer shuffles randomly, and deals normally. Your winning streak is the result of luck.

          function shuffleTheDeck () {
          var card_count = theDeck.length-1;
          var temp_card;
          var random_index;
          var i;
          for (i=1; i<=card_count; i++) { random_index = random(card_count + 1 - i) + i; temp_card = theDeck[i]; theDeck[i] = theDeck[random_index]; theDeck[random_index] = temp_card; } theDeckIndex = 1; }

          • Sam replied:

            I think there is one issue in trainer program.
            When is using late surrender with the dealer ace trainer first offers surrendering instead of insurance.
            And again I continue to win.
            May be there is a reason to imitate dealers shuffling, instead of mathematical random shuffling.

            • Author Ken Smith replied:

              Thanks! You may be right about the surrender issue, although it is possible that the surrender may only work if the dealer does NOT have blackjack. I’m not bothering to check because the new version is coming soon anyway, which is a complete rewrite.

    Hi Ken. Suggestion for future versions of your Strategy Trainer; ties push, rather than dealer wins all ties….?

    Thanks for ALL of the free information and training aids!

    • The current Strategy Trainer works just fine in this regard. Ties are a push. You are being confused by the way the bankroll is adjusted up when the bet is returned to your bankroll, and then down by the bet being made again. If you happen to look at the wrong moment, you only see the second half of that transaction.
      It works as it should.

  • Can I play more than one box in casino Verite or is just one box allowed to play?

    • Yes, you can play as many spots as you like at the table in Casino Verite. And you can choose to have other spots played by automated players if you like.

  • STUART said:


    • There is no download for the trainer here. If your device is not compatible with Flash, the current version hosted here on this page will not work. I’m hoping to have a new mobile-friendly version available here in early 2016, with LOTS of new features. It’s in progress.

  • How come when you split Aces and then get another Ace the program will not let you split beyond two hands that is a flaw that needs to be corrected asap. Thanks!

    • Yes, there is a problem with split Aces in the current version. A completely new trainer is in development and coming along nicely. I’m hoping to launch before the end of the year.

  • randall ducey said:

    Ive been playing on your trainer web getting ready to go to the casino. I noticed that amount won many times is not added to the total. I thoutht maybe I was making a mistake but after careful watching of several hundred hands I confirmed that to be the case. Kind of makes me wonder if the rest of the software has a problem.
    Check it out and let me know what gives. Great website otherwise.

    • No, there is no problem with the paying of winning hands in the free game. The confusion comes from the way that your balance increases after the hand, and then immediately decreases again as the next bet is automatically made. Many people only notice the second part and think their balance is going down after a winning hand.

  • Chester said:

    Single deck, S17, DAS, 15 vs 10. According to your B.S. generator I should hit, but this tells me I should surrender. What it the correct play? Does the discrepancy have to do with hand composition? (I had king-5)

  • Karim said:

    Hi Ken, I’ve been practicing for te Microgame Classic BJ where there’s no peek. So BS says no doubling 11 on dealers 10 or ace, cause there’s a too high chance for BJ. It’s not a big problem, cause I stick to the BS. But maybe in a later version, if it’s not too much trouble, you can include an option for peek or no peek? Cheers from Holland.

  • Another option which might be nice for the next version: the ability to re-play the same shoe (i.e., same cards come out again). I sometimes wish I could re-play a shoe with a different betting strategy just to see how it would come out, be nice to be able to re-play the same shoe again (I’d be fine with resetting my chip stack to what I had at the beginning of the shoe when re-playing too).

    • Author Ken Smith replied:

      If they’re giving you $2000 to show up, you should certainly take that, unless it means playing at substantially higher stakes than usual, or for longer hours.
      Which table? What betting? Those questions are going to depend on your edge and how willing you are to play with an advantage for these long periods. See my other reply for advice on software or books to answer those questions.

  • Luis said:

    Ken, you say that penetration menorr that 75% do not pay.
    You can explain?

    • Author Ken Smith replied:

      I’m not sure of the specific spot where I discouraged play at less than 75% penetration, but it really depends on the other rules. In six and eight deck games, it’s tough to get much of an edge at less than 75% penetration, and most players would consider that the borderline between games worth playing and not worth playing. In double-deck on the other hand, 75% is a great game. In fact, I’ve played lots of 50-60% penetration double deck over the years.

  • Andrew said:

    Something I noticed is that the dealer will still hit even if their first two cards have a greater total than mine and its under 17. No sane dealer in real life would hit when they already have a total greater than yours, right?

  • Anonymous said:

    It would be stellar if the trainer could be configured to only deal the most difficult combinations for the player. The strategy engine on is not very useful as a trainer because of that defect.

  • Jack said:

    I was wondering what should a player do if he lost the count of the cards dealt and does the count have to always be exact?

    • Author Ken Smith replied:

      The count does not have to be exact, but there are a few really dangerous mistakes you can make. If for example, you flip the sign, turning a negative count into a positive count, that would make you bet bigger money into bad situations. Obviously an expensive mistake.

      But if you miss a card every once in a while, that’s not going to be a big deal. If you truly lose all track of where the count is, just flat-bet the minimum until the shuffle.

      • Jack replied:

        Thank you very much I was also wondering should a player enter the deck just as it has been shuffled and if not how should a player determine a count when there is only half of the deck to start with?

        • Author Ken Smith replied:

          You can start any time during the shuffle. Just think of the cards already in the discard tray as being behind the cut card instead. You’ll have less chance of a good true count developing in that initial shuffle, because the effect of entering mid-shoe is that you reduce penetration for that shoe only. But everything works just the same.

      • Jack replied:

        I was also wondering how should a player go about betting when counting say the minimum bet is 2 and the maximum 10 with the bankroll of 500 at what count would you advise to increase bets from the minimum?

  • Chris said:

    i dont understand the double…sounds stupid please explain..i had 10 total..says it recomends going double other than a hit…dont get it..need help

    • Author Ken Smith replied:

      Doubling down gives a chance to double the amount of your bet after seeing your first two cards. For that privilege, you’ll give up the ability to draw more than one card, but in many cases, it’s a great deal. You mentioned a hand with a total of 10 in the first two cards. If the dealer has a 2 through 9 up, you should double down because you’re a big favorite to win the hand.

      For a full explanation of doubling, see Blackjack Rules: Part 3 – Player Choices

    Hello again!

    A new question regarding Lucky Lucky. I tried searching it up and apparently the Lucky Lucky (LL) bet is a profitable game when card counting is taken into consideration (apparently 2 deck is best for it). If @Ken Smith or anyone knows if this is still profitable at a 8 deck game, at a true count of +2 or +3, would it be profitable to blast the LL side bet? If you are expecting a bunch of face cards to peel off, or blackjacks and the dealer has a 10, you can still win those bets fairly often. With this in mind, would blasting the LL sidebet be another profitable play to mitigate that you’re not doing some crazy spread? Any info or knowledge regarding this would be amazing!

    Futhermore, in a couple weeks I will be making a trip to Reno. From podcasts I’ve heard from Richard Munchkin, Reno is not exactly a great place to card count? I read these stories where green chippers spreading 5-1 getting backed off. Any tips or warnings from anyone? My original plan was to go red chipping $5 or $10 and spreading to $100-150. Bad plan for the Pepper Mill place at Reno?


  • Josh said:

    Hello Again, I stumbled across this hand index recently (on a 8 deck shoe with good rules)

    when am I supposed to double down on a hard 12 against 5 and 6. I know it’ll probably get a lot of heat, but I just want the knowledge of being able to. On the ILL-18, rank 16/17 for 12 vs 15 at true count -2 and 12 vs 6 at true count -1, it says hit/stand. For this I am confused, if I am going to hit, shouldn’t I double it as I would never hit it again?

    • Author Ken Smith replied:

      Absolutely not! Don’t double a busting hand, ever. The hit/stand index reflects the fact that sometimes in negative counts you should hit some of these stiff hands, because the dealer’s likelihood of busting has decreased to the point where hitting is better than standing stiff. But you’re always at a big disadvantage on these hands, so you would never put more money at risk by doubling.

  • Josh said:

    Hello Again,

    I recently finished my first month of card counting adventures. With a spread of 1-20 betting units (rarely do I spread to 20), is winning 500 betting units in ~6 sessions or 30 hours an unreasonable win rate or am I on a super heater? There have been times where I have bet 20 units and lost 80 units from splits and dd. Also is this type of spread going to get me a lot of heat and get kicked out [yes it varies for each casino, whether it is low end or high end / but I just wanted to hear you guys opinion]

    Thanks Again

    • Author Ken Smith replied:

      You’re blazing hot, and winning 500 units in 30 hours is way above expectation. 1-20 is aggressive, but that’s probably a good thing. Don’t camp out for extended sessions, but it’s a lot easier to beat multi-deck games with that kind of spread.

      • Josh replied:

        Thank you for your quick response, follow up question!

        With your experience, what do you think a general estimated 1-15 or 1-20 spread would make hourly in betting units? I’m playing a 8 deck with good penetration, H17, double down any card, split aces 4x, no surrender, yes insurance, 3:2 payout.


  • Thanks so much for your strategy trainer, it’s helped my game so much! One feature I’d like to see added is the option to disable the display of the player’s hand total, having my hand total automatically displayed is a distraction when I’m practicing my card counting (I need to be able to do both simultaneously).

  • Hello thanks for previous answers, new question!

    I have a relatively small bankroll and comps and match plays really make a huge impact on my future game (have not frequented many times yet), but wanted to clarify some thoughts. In a hypothetical situation, if I was to be receiving a $100 match-play bonus, is my EV out of that around $97 (assuming I play it at a house disadvantage) or is it around $47 for player (since house has a 3% edge making it around $53 for the house). Sorry if this seems silly, but I just wanted to make sure about the math before I dive into this.

    Regardless, would this match play make a red chipper who spreads $10-100 (max bet) at a very high advantage or is negligible towards the hourly / bottom line? I assume even at a $47 free-roll, that has to impact a $10 min when max is $100.

    thoughts are appreciated

    • Match plays offer a huge boost for low limit players. In fact the edge from coupons will often dwarf the rest of your advantage. That’s a good thing!

      The EV for a $100 match play will be less than half face value, but not for the reason you were trying to give… Match plays are usually discarded after one decision, win or lose. So it’s not like a regular bet that you keep on a win.

      Play all of them you can. Very helpful.

  • Hi,

    I’ve been trying to google this and cant find any forums or info regarding the matter, so here goes:

    In a true count of +6 (or something of that significance), is it ever correct to stand on a 12, 13 or 14 against a 10?
    Knowing that the probability of the next card being a 10 and more often busting than improving you, should you stand and pray the dealer has 6 or less and take that 10? Or do you always hit since too many cards improve you (and refer to basic strategy)?


    • Short answer: Just always hit 12, 13, and 14 vs Ten.
      Longer answer:
      For 12vT and 13vT, the count basically never gets high enough to stand.
      With 14vT, the appropriate Hi-Lo index would be very high. I know it is more than +10 true count, because I ran very in-depth data for the range of -10 to +10, and 14vT was still “always hit”.

      Wong’s Professional Blackjack book shows “Always Hit” for 14vT with the Hi-Lo count, but for his Halves count, he gives an index of +10.
      This is likely because the Halves count includes sevens, which are quite important for that specific hand.

      • Josh replied:

        @Ken Smith:

        Hello and thanks,

        If I recall on what I’ve read so far (new to this), in high true counts (let’s say 6+), then for hands 15 and up, you should always stand correct? Like a +1 and you should stand on 16 vs 10, at what count would I have to stand on a 15?

        Thanks again

  • Just started playing and want to get really good at black jack can u install a cheat such as best times to stay or hit? So it becomes instinct after playing a few hundred hands

    • I assume you mean you would like a feature (optional of course) that shows you the correct play before you make the decision.
      The trainer already corrects you on mistakes, but I can see how some people may like an option to just see the best play beforehand. Sort of like learning with flashcards. Sounds reasonable for the new version.

      • Randy replied:

        I like it like it is. If you add the flashcard type version I hope you would make it an option like choosing how many decks, etc. If it were permanent I think I would think less before hitting, standing, or doubling down.

  • Can you make an option to get rid of the count? Adding them in my head helps me train. Thank you!

      • Bob replied:

        Thanks! I’ve just started learning and I get in the habit of looking at the hand count rather than figuring it in my head. If I was experienced I would probably just be able to see the cards, but since I’m not I get used to looking at the number rather than the hand. It doesn’t cause a whole lot of problems until I get a soft hand then I tend to act on impulse and say try to surrender on a soft 15 rather than hit. Overall this is my favorite trainer so far. Awesome work! Removing the count would make it perfect for me. Any idea when the new version might be rolling out?

    Hey Ken,

    • Matt replied:

      right half of screen is showing 2 guys, one has his arm on the others sholder. if you were to tick under the picture it would send you to the card counting section. I cant figure how to get rid of that stuff on the right and bring the game over. nothing wrong with flash player.

      • I’m guessing your screen resolution must be set quite low. I would first check to see if your system can run at a higher resolution.
        (In Windows, look under Control Panel / Appearance, and there should be a screen resolution setting somewhere.)

        As another work-around, try this… Make your browser width even narrower, so that the site will know that it can’t fit the sidebar on the right. At some point, the sidebar will reposition to below the game.

        Let me know if either of these ideas works.

        In my version of Chrome and also Firefox, the Flash player will resize the game to fit the available space, but I suspect that not all versions can do that.

  • trying to use the BJ strategy trainer. cant bring the game into full view. ????????????

    • I’m not sure what you mean by “can’t bring the game into full view”.
      Can you describe what you see instead of what you expect?

      Have you tried a different browser, like Chrome or Firefox?

      Do you have Flash player installed and running in your browser?

    I’m going to be playing at a casino next week with No surrender, 8 decks, S17, and no peek. Got a couple of questions about strategy in such a situation;

    1)Do I DD with a hard 11 on dealer’s 10 or hit?
    2)Do I split 8s on dealers 10-A or hit?
    3)Do I stand with a soft A/7 on dealer’s 2?
    4) Do I split A/A on dealer’s A or hit?

    Appreciate your help and any rationale you can provide for choices in these situations given the conditions of the table at which I shall be trying my luck. Thanks..

  • OK, thanks! I admit I didn’t know the difference between early and late surrender. Thanks for explaining!

  • I think there are some flaws in your basic strategy regarding early surrender. The game recommended I surrender with 12 vs a dealer ace. That isn’t right, is it? It also recommended I surrender with a 7 vs an ace. That can’t possibly be right!

    • Yes, those are correct plays for “Early” surrender, where you can surrender before the dealer checks for blackjack.
      But you probably don’t want to choose that rule. It’s rare.
      Choose Late Surrender and you’ll get the advice you expect.
      To learn more, see my article Blackjack Surrender Explained.

  • Bob Boose said:

    The game has been slow and jerky the last few days. I have a very fast internet connection so I know the problem must be at your end.

    • Once the current version of the trainer is loaded and running, it runs locally on your machine. Something has to be causing Flash to run slowly on your machine.
      Note that this will work completely differently in the eventual new version, which will be interacting with the server to provide additional features.

  • I’ve recently started training with your program very helpful thanks it just seems that on a pair of 4s againsts a 6 i woudve been better off doubling? also i always hit on a12 0r 13 against a 2 and more often than not i woudve been better off standing (based on my own tracking?thans

    • Splitting 4s vs a dealer 5 or 6 is better only when the rules allow double after split.
      If the actual numbers would help, here they are for a 6-deck S17 DAS game:
      Splitting 44v6 wins 0.168 of your initial bet on average.
      Hitting makes 0.124.
      Doubling makes only 0.104, making it the third-best option.

      You mention hitting 13v2, which is not correct. You probably meant hitting 12 against a 2 or a 3 up. Again, just trust basic strategy.
      With (8,4) vs 2, hitting loses 0.254 of your bet on average. Standing is quite a bit worse, losing 0.291 of your bet on average.

      Short-term results can be very misleading. Just trust the math.

    I wish at some point this site could include a strategy trainer for Spanish 21.

        If you could somehow put it into operation, this portal would be even more awesome than it is now.

      • Wight_Gypsy replied:

        It would be stellar if the trainer could be configured to only deal the most difficult combinations for the player. The strategy engine on is not very useful as a trainer because of that defect.

  • I like the ease of use. It’d be nice, as a novice to the game, to understand why the strategy is what it is. It’ll tell me what I should have done, but not why. That makes it difficult to not make the same mistake in the future. (Also, this form says the email is optional. It’s not)

    • An explanation of why basic strategy recommends certain plays is on my list of future blog topics, and maybe the new trainer can offer a link to that when it is available.

      As for the emails not being optional when leaving a comment, thanks for letting me know!
      It’s fixed now, and comments no longer require an email address.

  • pair of 4s
    against a 6 your suppose to split but 90% of the time id have been better off doubling down?

    Is there going to be an European Style with no peek in the new version?

  • Peter said:

    I could never understand this about card counting. If the deck is rich in ten counts and aces…It is said it is too the advantage of the player…..How can it not be advantageous to the dealer if the dealer is drawing cards from the same rich deck ? Please explain.

    • You are correct in thinking that the dealer is just as likely to get those extra face cards and Aces as you are. But those cards are more valuable for the player for two reasons:

      1) If you get a blackjack, you win 3:2. If the dealer gets a blackjack, he only wins even money.
      2) The dealer is required to hit all stiff hands, while the player should stand when the dealer upcard is a small card. The dealer therefore busts more often when the deck is rich in face cards.

      Thus the good cards help the player more than the dealer, and that’s why card counting works.

        Thanks, I had the same question. The answer makes a lot of sense. Thank you.

  • I think there was an error in my variation, maybe not though.

    The game I am playing is: 6 decks, Hit on Soft 17, Late Surrender, Peek

    I had a hard total of 17 with an Ace, 6, 6, 2 against a dealer’s T, my basic strategy chart from this site says to Surrender o/w Stand, since I could not surrender obviously I stood but the coach told me hitting was the best play. Is this an error in the application or something I myself and missing? Thanks a lot. Loving the site.

  • Great game.

    I found a bug while playing this morning. Split 10s three times. The first hit was a 9 and I stand with a 19. The second hit was an ace and have a 21, but am unable to proceed because the hit and stand buttons are not available.

  • Ben Nelson said:

    I love the trainer and how helpful it is; is it possible to add a feature explaining when to change from basic strategy? For example, when the true count is negative 2 and you’re deciding to double a hard 9 vs 3(an example off the top of my head, not sure if it makes my point), it would be helpful to see the variation rule come up and not just the basic rule.
    Great site and thanks for all the info!

    • Hi Raymond,
      I notice you are visiting from a mobile device which likely does not support Flash. That did not change with the new website.
      Perhaps you were previously visiting from a desktop computer instead?

      If you were previously able to access the trainer from your mobile device, please let me know.
      But I am unaware of any that support Flash.

      By the way, now that the website design is complete, I can get to work creating a new version of the trainer.
      I’ve been planning that for a long while, and have a lot of improvements in mind.
      For one thing, the new version will not require Flash, and should work on any device.
      I plan for it to also optionally be multi-player.

  • I’m extremely suspicious that this program isn’t fairly generating random numbers. It consistently deals out high cards straight from the beginning. Time after time after time, I set it to 2 decks, and I see extremely negative counts, very quickly, and the reason is because lots of high cards come out straight at the beginning. Is it possible you programmed this thing to kind of simulate “worst case scenario” conditions?

      • Mark replied:

        Yeah, I guess that’s believable. Stranger things that one expects are conceivable can happen by chance. I do remember this one time I played monopoly, we played for like an hour and fully one out of every 6 rolls was double-6, and that wasn’t on any computer, they were real dice, And I just got my clock cleaned by a casino. I’d win 25 dollar bet (min bet on the 2 deck game) after 25 dollar bet after 25 dollar bet when the count was negative or not positive enough, I endured another player with a superiority complex (ironic) chastising me for being too “afraid” to play basic strategy (sure, it was fear that made me deviate from basic strategy), constantly griping at me for messing up his game by “playing badly” (like standing on 16 against a 10 when the count was like +7), and eventually actually PAYING me 25 dollars to LEAVE the table (!!!), then the count would get high and I’d bet 50, or 100, this one time the count got to +13 with 1.3 decks left I reckoned, I doubled down on 10 against 10 with 200 on the table, and of course I got a frigging 2, and the dealer got the 10 of course…. and then the EXACT SAME THING HAPPENED AGAIN NEXT HAND! And at the end of the day, 3500 dollars down (with 500 left), security came to my table and said “we believe you are an advantage player” and invited me to play any game but blackjack. Gee. THAT was fun. It’s hard to believe that I supposedly really did have an advantage, but I did a calculation and it turned out that risk of ruin was minimized by betting 54 dollars for every 1 the true count was past 1.8 (or betting as if I had about 15000 dollars regardless of the amount I actually had), and that risk of ruin was about 76% starting from 5000 dollars, so I did know it could go that badly pretty easily but damn it sure seemed like some deity had a grudge with me. But what can I do, no one would ever hire me for an actual job. What happens whenever I touch the stock market? 2008 happens is what happens. I just suck at everything.

        Oh, by the way, you say on your website in your blackjack lessons that you should take insurance when the count gets to 1.3 or so. This is wrong. The actually correct answer is actually exactly 3 and a third. Or if you want to maximize utility (expectation on a logarithmic scale, a.k.a. kelly optimality) 3.29 since the insurance bet has negative correlation with the result of the main bet. You’d think it would drop more than from 3.33 to 3.29, but nope, that’s all.

    • Randy replied:

      I’ve played my fair share of blackjack in actual casinos. Many of it counting cards. This happens nearly every time. It’s a real pisser….you put all that time and effort into learning how to count cards only to realize the count is negative so often and usually right out of the gate. It’s very seldom the count goes high or in your favor. Counting cards certainly works but if you’re careful not to expose yourself by betting large amounts while the count is high you end up barely getting by. I’ve been working on progressive betting strategies for years now with no luck finding the perfect one.

      • Lizzy replied:

        Thanks for the input Randy. I have been down the ‘card counting’ road too. I am no longer counting on blackjack to make me a million dollars. I play occasionally, but when I play…I play to win. I think this could be a great second job or play to earn some extra money, but to make a living doing this? Not many can.

    • Windar replied:

      In BlackJack 16 of 52 cards 31% have a value of ten and 4 of 52 cards 7% are aces. This means there is a 31% or 1/3 chance of getting a high card which is a pretty high chance.

      Anyways my opinion is that no matter how many decks there are, blackjacks should be dealt 7 times out of every 100 cards in game play. Or to put it another way one of every 14 cards in play or about one in five hands of play could be a BlackJack because that is when an ace should appear. And that BlackJack could be for the player or for the dealer.

    I also find the black back ground hard to watch. Thanks for the strategy trainer. It’s a great tool.

  • MARK WHEELER said:

    The new display, i.e. black screen on a white background is glaring. It makes my eyes hurt. It causes distortions in perception and causes a loss in concentration. Please change back to the green background or anything easier on the eyes.
    Thank you for the service of the strategy trainer. If you have time, how does the Surrender option effect the win/loss ratio if surrender is counted as a loss?


    • A surrender in the trainer is counted just like any other loss, so it affects the win/loss percentage as well.

      On the screen colors, I may experiment with that a bit and see what I can come up with. Thanks for the feedback.

      • MARK WHEELER replied:

        Can you quantify the change. I would expect the win ratio to be less even though the $Loss would be less. I have been calculating the winning percentage at 47.6. Is this about correct for the dealer hits soft-17 option. The Beau Rivage, Biloxi plays Dealer Hits Soft 17, has late surrender and re-split Aces up to 4 hands. This seems to offer good odds. What are they? Thanks again for the Basic Strategy Charts and your many excellent articles.


        • You are correct: with surrender the percentage of hands lost will be higher, but the money lost will be lower (assuming you use surrender at the appropriate times). This is one example of why looking at the win/loss percentage is a poor way of judging a game.

          I recommend paying no attention at all to win/loss percentages, because they don’t tell the whole story.
          That is especially true when using the trainer. The trainer’s percentage display is simply not useful, as it even treats a push as a loss. The win percentage is just the number of wins divided by the number of total hands. (The next version will be much improved in that regard, when I get time to finish it!)

          For the Beau Rivage game you mention, I plugged in 6D, H17, and Late Surrender at the Strategy Engine:

          That shows a house advantage estimated at 0.58%. The Resplit Aces rules decreases that by about 0.08%, so this game has an expected loss of 0.5% of your initial bets.

          That is the important number, regardless of what percentage of hands you will win or lose.

  • Steven said:

    Thank you for everything, man. I am on vacation for six months and I have been on your site almost everyday for the past three. I have basic memorized and have started working counting in to my play. Thank you for teaching me these skills through your site. The new format looks great.

    • Greg replied:

      This is one poor trainer. The house has an unbelievable knack for pulling a 14-15-16 Right out of their asses and making a 20 or 21. Almost always beating you by 1. Definitely rigged.
