effect of ace-count for 11 against 10, no hole card?
Basic strategy of course tells not to double 11 against 10 if you lose all to a BJ. Counting systems usually give index numbers for positive counts. But I did not read a number for the ace count, that is doubtless very important. Who knows the effect of removing aces on the decision if to double or not? Or even better a 2 Parameter index depending of the high-low count and the separate ace count?
