    Any BJ simulation software that using composition dependent strategy ?

    The composition dependent strategy should be calculated from remaining cards, every single card that remove from the deck may affect the correct strategy especially for single deck game.

    For a BJ game :-

    1) Single deck
    2) Peek rule
    3) H17
    4) No surrender
    5) DAS, Double after split
    6) Double on hard 10 or 11 only
    7) Original hand split once to form 2 hands, NO resplit.
    8) Split Ace only receive one card
    9) Bet max 3 hands per round
    10) Shuffle after each round.

    The house edge is 0.37%.

    Is it possible to reduce the house edge of 3rd box to 0.1%( or lower ) with computer perfect play ? What is your estimate ?

    Eric usually uses a small number of cards if CA is being used. His CA is stronger now but in the past CA was limited to around 1 deck.
    I was trying to be helpful and find it but Don didn't participate in the threads by Eric that seemed most likely to be on topic. Eric usually only participates in the threads he starts with rare exceptions. Eric's threads are some of the best on the site. I recommend reading them all.

    As for my experience with the topic of CD and indices. The composition of the hand can affect the index especially if key card(s) are in the matchup either counted or neutral. Key cards counted poorly for the play or neutral key cards have the most potential impact on the index. The effect is also related to how many decks remain to be played. It is a lot more accurate to think of it as side count adjustments for a side count you started that round than a CD adjustment. You can factor in all the key cards on the felt rather than just the ones in the matchup. Also the adjustment is weighted properly for the number of unseen cards. Remember the rest of the unseen cards will balance to neutral in the long run for the key card ranks. An index is a long run computation based on the info at hand. So whether you were at a surplus or deficit of key cards before the hand doesn't matter because over the long run using the index adjustment things will balance out to neutral.

    I don't know how Stanford Wong generated his indexes for Zen. I have written my own index Gen using the strategy you described. For 6D, the indexes I generated are almost identical to Zen indexes published. When I wrote the program, I had only PA casino rules in mind, so I did not make it suitable for single deck. So I can't really answer your question.

    You don't mean Wong, you mean Snyder.

    Take a look at the methodology I suggested on pp. 45-47 of BJA3.
