New at ace sequencing - question about a very simple scenario....

I'm just wondering, what is the profitability of memorizing key cards right before an ace, in a 2 deck game, considering...

1) this person can memorize 4 key cards with perfect accuracy
2) your gathering your key card information every other shoe, and doing the big bets in the shoes between (that is you big bet when you've spotted your key card as the last card of a given hand)
3) flat betting \$5 on normal hands, 2x\$100 when you've spotted your key card as the last card dealt out of the hand
4) playing nothing but perfect basic strategy
5) the rules are 2D H17 DAS DOA 50% pen, a heads up game with about 150 hands per hour, no resplitting aces
6) can only go from one hand to two hands once per shoe (pretty gay). To compensate, if a situation arose where the person had bet 2x\$100 and had to go back to \$5, he would just bet 1x\$100 if another key card came up in the same shoe.
7) The dealer is the world's most average shuffler (not good, not bad, just an average of all the dealers in the world)

If the profitability is anything decent, wondering if a person might know the volatility of this? Lets put it this way, what would be the Risk of Ruin with a \$10k bankroll?

I know the Zen man is experienced with this, maybe he can help me out :D (wink wink)

Whoaa, now THAT's a good question(s), since I do it (2D Ace Tracking) and I don't know the answers.

Anyone?

Can this be simmed? zg

Here's my input:

The risk of ruin is going to be reasonable. The risk of ruin for straight counting with a 2X\$100 max bet and a \$10K BR is reasonable (but not low.)

1) Come on don't be a wimp, you can memorize more than 4 key cards. Although with 50% pen that will be the average number. Bad pen hurts you in sequencing just like it does in counting.

2) Oh you've got to be kidding me, you can't play back and record in the same shoe in a DD game? Practice, practice, practice!

3) That spread's a little steep, might draw too much attention in the places where you play. Also might look like cheating. Maybe tone it down just a little.

4) You can probably get away withe some cover plays. Maybe research what the riskiest soft DD plays are and don't use them when you have large bets out. That will decrease your volatility.

5) Decent rules I guess.

6) That is gay. It wouldn't hurt much to play 2 hands on ordinary hands. You can work some rudimentary steering into your repertoire when aces are coming out in the middle of a round too.

7) Average is good. I assume you've studied the mechanics of shuffles as they pertain to ace location, but that is something best not to discuss publicly.

Here's a DD ace location trick for you! Once you have recorded a key card, you can manipulate your discards such that if you see the twin key card later in the round, the card following it is also a beneficial one. An ace gives you a 50% advantage, a ten card a 15% advantage, a 9 gives you a 1% advantage, and the other cards all give you large disadvantages (but some worse than others.) Example: you have keyed the Eight of Spades to an ace. On the next round, the other Eight of Spades comes out, and you have a choice of putting it on top of a King or a Six when you hand it back to the dealer. You'd choose the King, for on the next round when you put a big bet out after seeing the Eight of Spades you'll be happy to get either an Ace or a King.

One more thing: you mention 150 hands per hour so this sounds like a heads-up game. You want to be very careful when ace sequencing about the dealer getting the ace instead of you, and when it's just you and the dealer, it's easy to split the aces 50-50. Even with a 50-50 split you still have an advantage, but not the kind of advantage you want. This is a game where it's helpful to have a bunch of hands (preferably those of a partner) between you and the dealer to maximize your advantage. I remember a sequencing trip where I was confounded all night by the dealer getting the ace I predicted for me.

Good stuff monkey.

It totally didn't occur to me that you can manipulate the card order in a pitch game, lol.

Good idea on how to make both your key card and his twin brother viable.

I can see myself being able to memorize key cards and utilize key cards in the same shoe (not alternating). Going beyond 4 memorized key cards would be tough though :D.

I know very little about the "mechanics of shuffling". I've seen terms like "riffle" used in these threads. Hence why I said "the worlds most average dealer".

Any good literature on ace sequencing in general, (internet or paper) you can recommend. Preferably literature that deals a lot with 1-2d and has lots of pictures :D

P.S. oh yeah, one more thing I forgot to mention...at this particular joint, any play on two hands has to be played at \$10 minimum. yowzers

You don’t mention the casino’s shuffle procedure (which is smart ), but that is something you need to look at. Many DD shuffles are simply not sequenceable while others are very profitable. Here’s Sonny’s patented Six-Step program:

1) Analyze the shuffle and see what sort of accuracy you can expect. You might find that the shuffle is not predictable enough to play.

2) Scout the dealers and find the ones that you can afford to play against. By this time you should know what kind of shuffle to look for. Find the dealers that shuffle the way you need them to. This might include dealers that don’t follow the house procedures or dealers that follow them perfectly.

3) Crunch the numbers, get your EV and SD and set up a betting strategy. Sequencing can be very dangerous, especially with a difficult shuffle and/or lots of steering. You need to verify that you are playing with an advantage but also within your tolerance for risk. Just like with card counting, both overbetting and underbetting can ruin you. You need to know when to bet, how much to bet, when to spread to multiple hands (if at all), and what misplays you can afford to make in order to steer the cards.

4) Practice at home until your accuracy is acceptable. Have several other people shuffle the cards for you. Teach your friend(s), neighbor(s), significant other(s) how to shuffle like the dealers do. Try to find a way to beat each of their styles, or at least determine why you can’t beat certain people's technique.

5) Go to the casino, find one of your dealers and “back-sequence” the table for 5-10 shuffles. If your accuracy is acceptable, sit down and play. If not, back to step 2.

McDowell's book will definitely open up your eyes to many possibilities. Also read Snyder's cookbook for some sequencing tips.

Thanks for the info.

Making misplays to steer cards? Fascinating

In a pitch game you can set your keycard where you want it, sometimes. In a shoe game - no touch - you can HIT your paired Aces instead of split and create a super keycard to follow. Both are manipulations of card order. zg

Hello, I do the job at 6 deck games.
First, the person must remember 2 key cards and not one.
Then he must find out the gaps between the 2 keys usually.
To avoid that the dealer doesn't get the ace, it's the best to play
5 spots when he expects an ace.
To reduce the flux, I would only play 1 spot.
The volatility is very low if you play one spot.
I would split and double only against dealers 5 and 6 when I don't hit an ace.
It sounds unbeleaveble but the highest flux I had in the last 1/2 year,
playing 20 hours the week against 6 decks handshuffled and CSM's were
6 units playing one spot, only about every 6th time I played 2 spots when I
expected the ace at the 2nd spot.
With that bank I see no Risk of ruin, specially when you use the Kelly Criterion.
In DD games that you mention is a problem if the dealer gets the ace,
as I know he has then an advantage of 36%, while you have an advantage
of 52% when you hit the ace.
What I said, find out the gaps between the keys.
You cannot play every seen keys, but you can register them in your memory
and the gaps.
Very importand, write down the results of your game very careful.
And the cards between the keys.
How often you hit the ace, in every case more than every 13th time ---loll.
The more often the better.
In handshuffled games I hit the ace every 4.5th time.
In CSM's not so often.

For example 1.1. no gaps, or 2.3. the second key card came as 2nd card and the target card (ace ) came as 3rd card.
write it down, when you make a break, or go to the wc.

To memorize 4 keys in every 2nd shoe I think are enough.
150 hands an hour is a very fast game.
Better would be 3 keys in every shoe, I think it's possible.

Think of Brian Pridmore, he is the world Champion, remembering
a deck of 52 cards in 26 seconds.
My dream is to beat that.

So you tried keying Aces at CSM? zg
