Crush-count experts: A question to playing efficiency 11 vs 10

I am so lucky to play in a game offering the over/under 13 bet and use the crush count to decide. I cannot count alone 2 different counts, so I only concentrate my mind to the crush count to decide if to bet over/under or not and play basic strategy at the box. My assumption is now: Because the crush count counts 10s as positive and aces as negative it should have a good correlation in decisions whether to double 11 against a 10 or not, especially because it is a ENHC game. Am I right? And who knows index numbers? Thanks and best Regards.

to come up with the Correlation Coefficient. Use Theory of Blackjack, by Peter Griffin (editions 4 onwards would be best) and follow the advice text on using his Effects of Removal tables. Snyder, at one time sold regular playing indexes for a level one over/under optimized count.

You are a very lucky man indeed provided there is reasonable penetration. Your penetration needs are not severe either. You are not getting responses because few of us are so lucky.

The algebraic index formula would be -m [from Griffin's EOR tables]*ssp[the sum of squares of your count --ie the Crush Count]/IP [the inner product of the EORs and your count AKA the dot product of the EOR vector and the count vector{I know the last is wordy and confusing but it is a close paraphrase of the explanation of Moss'es similar formula and some on bjmath.com somehow think that is clearer --jeesh!}]. This is the infinite deck formula, which, assuming it is a 6 deck or greater shoe should suffice.

I have a thread with Caccarulo, on bjmath.com where I am thinking that a final algebraic method for single deck might involve some modification, but you should not need to consider this.

If you are player over/under single deck THEN you might consider those details, and YOU ARE TRULY, TRULY, TRULY VERY DAMN BLEAPING LUCKY INDEAD---email me where!!!!!

The decisions where the Crush is good for playing decisions are relatively unprofitable. A good way to estimate profitability for a decision, that gives a relative rating only, is just multiply the figures for relative importance of each decision, in various games, from ToB, by the correlations of each decision.

For doubling and splitting against aces and tens.
