  1. Hello,

    I am wondering if the results of your basic strategy come from estimations with millions of trials or simply calculated with a good method of
    calculation.
    I designed a method of calculation for any decision and I arrived allmost to the same basic srategy than yours. Although some differences.
    For example : I suggest not to double your bet A-2 or soft 3 against a 5
    E ( dbl soft 3 against 5 ) = .1272084 E = mean
    E ( hit soft 3 not doubling ) = .1336275

    Could you please write if your results were estimated or calculated to arrive to your basic strategy.

    Thank you and Best regards.

    On a long run I should hit A-2 against a 5

    1. The basic strategy charts on this page have been known for decades. They have been calculated and verified by billions of hands of computer simulation over the years. The correct basic strategy for A2 and A3 versus a dealer 5 is to double down for any number of decks and rules.
