For multi deck game H17 that offers Surrender when you have a 16 or 15 you Surrender vs. certain upcards OTHERWISE hit. The “otherwise hit” part is missing. It only says “R” when it should say “Rh”


Could you please make strategy cards for Spanish 21, and for composition-dependent single deck?

LV Bear

Ken has retired. There is too small a potential market for the cards you request, sorry.


I would agree about composition-dependent, but Spanish 21 is quite popular, in my opinion (WA).
Good luck to Ken! Those are great strategy cards he made, they are the best. I have both standard and advanced sets, plus about 20 assorted 4/6/8 S/H17 strategy cards I give to people at my home game where we practice blackjack.

do you have cards for spanish 21, if not do you know where?


Hi Ken,
I just received the advanced strategy cards and some (but not all) of the numbers for the 2-deck H17 game are different than I’ve seen elsewhere. I saw somewhere (I think Norm W. wrote in his forum) that you should use indexes based on the same method of true count derivation that you use for counting. I am currently using flooring and am wondering: 1) What true count method you used for arriving at these numbers and 2) Whether you think this is the reason for the differences in some but not all the numbers. Most are within one integer, but some are very different….for example, elsewhere for this game I’ve seen the index for 12 vs 6 is -3, yet you have it on the card as -6! Obviously this is a big difference and could result in one $$ won or lost so am wondering if you can clear things up. Many thanks!

I have read in another book on blackjack counting about counting the low cards then divide by the number of players have knot tried this way as of yet. I am doing real good just using your blackjack strategy. how about the low card system above. any one has it been try-out


Wait a min…is the advanced strategy card(s) what I think is is??? Is this the basic deviations based on true count on a card? Already bought three of the basic cards some time ago…I didn’t know what deviations were at the time…I do now…lol.


One of the local casinos has a couple of tables with oddball rules, such as one where the house will pay for a double or split under certain conditions. Any easy way to calculate odds for such oddities?


Yeah, that’s the one, though the nuances are slightly different. They also have Triple-Up.

I may have to hit up my younger sibling to bodge something together. XD

Hi Ken
My casino here has the rules for blackjack: 6 decks, CSM, D any 2 cards, DAS, soft 17 ,early surrender, no peak,but no surrender if banker has A . Your basic strategy engine says the banker has the edge of -.08%. That mean that the player has .08% against the banker?


The advanced strategy chart I am using for double deck assumes surrender is an option but it is not in all the games I play. So, for 15 against a 10 where it says to surrender against a 10 or stand if TC is at least 4, I assume all I do is replace surrender with hit in this case and I am good, is that right? In other words just treat the surrenders as if they said hit but I still stand if the TC is at least as high as index.


I have now read all your classes and received your advanced strategy cards in the mail.

I seem to have discovered what appears to me an inconsistency in the variations.

For my double deck game (see comments above) advice on card for when I have a 12 against a 2 is to stay if the true count is at least 4. The card would on the other hand have me hit a 13 against that same 2 with the same true count of 4. How does that make sense, to hit the 13 but to stay with the 12 with the exact same circumstances?

To be clear, the card specifically says with my 12 to hit against the 2 as long as the TC is 3 or higher and with my 13 to stay as long as the TC is higher than -1 but that results in the above advice, right?



Yes, I seem to be confused as to the relationship between the index number and when you perform the alternative from basic strategy play. I latched on to this statement in your lessons.

“The general rule for understanding the Basic Strategy Variations Matrix is this: If the number in a slot is 0 or a minus, then that play is a Basic Strategy move that you should make as long as the count is higher than the number shown.”

So, 13 v2 with index -1 would mean play stay as long as count is higher than -1, like +4. What am I missing?

Of course it seems fundamental that I understand how to understand the index numbers so I will ask about the general rule above. When is that not the rule or is that always the rule? And what about when the index is positive, same general rule of playing basic strategy move as long as count is not higher than the index? Based upon what you said with 12 v 2 hitting until you get to at least +4 sounds like the answer is yes but it seems important to get this right.



Sorry, I confused myself. Let me restate my reply.

First of all, is it always the case that with an index of 0 or negative that you play basic strategy move only if the count is higher than the index, otherwise play the alternative?

Is it also the general rule that it works the opposite when the index is positive? In other words, you only play the basic strategy move if the count is equal or lower to the index? By general rule here do we also mean “always?”



Since I play double deck where dealer hits soft 17, can double after split (except Aces), can double any two cards and no surrender, what would be the easiest next best counting system to learn once I have mastered hi-lo (the easy one you teach) and what would be the best one if I advance that far? Also, should I count Aces as minus 1 or should they be neutral?



Thanks again Ken.

The strategy engine does not allow you to pick the rule where you can double after split except aces. Does the fact that you can’t split aces have any bearing on the basic strategy decisions for double deck?

Separately, is there a simple way to explain why in the first place basic strategy changes from 6 deck to double deck. I understand that if you are counting there may be a difference but if you have no idea what is coming (or what has been played) then what does it matter if there is one deck left or 5?


Ken. I am interested in counting double blackjack. I purchased the advanced wallet cards. My issue is that the matrix under lesson 23 is inconsistent with your double deck basic strategy. For example, on the matrix it says if you have a pair of 2s and dealer has a 2 you should just hit (no number so doesn’t matter what the count is). On your basic strategy engine for double deck (leaving the default drop downs for everything but # of decks) it says for this same hand to split (split up to dealer having a 7 in fact). Is this a mistake and if so which one is right? Thanks,



First off, thanks so much for the quick reply; it makes sense (I didn’t know the acronyms well enough to see that I was looking at two different sets of rules).

So, I have basic strategy memorized although I never knew it varied for double deck so there are about 9 hands I have to memorize to be 100%. Now I am contemplating moving on to the index variation piece by using your cards. I am looking for guidance on cost vs. benefit. For all my purposes by the way I am dealing with Mandalay Bay or Palazzo, which means H17, Da2, das (except Aces), no surrender and I am starting with at least basic strategy and counting where I will up my bet by up to 8 times minimum (sometimes more).

First of all, assuming penetration of about 66% (deck + 1/3rd deck) and varying bet up to 8 times, about what are my odds (i.e. 1.5%)? Second, if I completely incorporate the index variation piece, what impact does that have on my odds? Lastly, is there an in between that you recommend that is a starting point for my next trip to Vegas that would provide me the most bang for my mental buck? For example maybe I skip the ones where I have a pair as those are a lot less common I think than soft hands and the rest or maybe I just disregard all the ones where the variation starts above 3 or below – 3 because those are less common counts. If you have a suggestion please make it and let me know if you can about what improvement to my odds that might offer vs. just counting with basic strategy.

Last question, how much leverage do I get by upping my bet by more than 8 times? I usually pay $25 minimum and sometimes find myself doing two or three hands each with a $200 bet when the count is high towards the end of the two deck shoe (in particular when there are a bunch of Aces left). While this has risk of being asked to leave for counting I wonder if this is actually more impactful in terms of my odds then worrying about the index variations in the first place, thoughts?

I really appreciate it.

Kind regards,



Do you have any information on how to beat California Blackjack? Such as when to bank the game?


Purchased your Advanced BJ strategy cards. I have seen several people bring a casino version as an “allowed” cheat sheet to play basic strategy at the tables. Even got into a “fun” argument with someone who said I played a basic decision incorrectly based upon their card. I told him I had not and he should check again. He pulled it out and “lo and behold’ I was right……..LOL Amazing how confusing to many A-7 is, right?

In any event, round about way to get to use of your Advanced cards (stealth mode) in casino. I have them; been tempted to use them at tables but seem to chicken out to actually pulling them out to use. Illustrious 18 I have memorized pretty much. Have you received any feedback from players on them yet? I want to play “dumb” but not THAT dumb at the tables. Would hate for them to confiscate my card………..haha. But it does concern me if a pit boss were to ask me for my card and I had to show it to him. Your suggestions?


Have used at the table many times and have been told by pit bosses that it is perfectly legal. No problem.

Would love your thoughts, please comment.x
