    Most likey due to computing the probability of each dealer hand for 2-A times the 3072 total hand the player can have?

    54,433 * 3,072 = 167,218,176

    Do you mind to help me to calculate the CD ev for (A,2) vs T, 8 deck, ENHC.

    Most calculators give CD ev = -17.028%, except CD ev by icountNTrack calculator is -16.189%.

    Why the ev so much different ?

    How to contact icountNTrack?

    Give the following Rules :

    8D
    S17
    ENHC

    CDCA gives 17.03
    MGP BJCA gives 17.028

    Check to make sure your rules match that of mine. Most likely the CA assumes different Ev's dues to discrepancies in rules given.

    NOTE: The above also assumes Composition Dependence for all Expectations!

    dog,am_1234, thanks for your reply.

    Are you saying that MGP and CDCA CD ev is based on subsequent MULTIPLE(more than 2 cards) cards composition ? or just based on first 2 cards composition ?

    I also noticed that icounNTrack calculator always give different ev for hand with first two cards soft total vs T or Ace, for example (A,2) vs T,
    (A,3) vs A, (A,5) vs T . . . . .

    Reread my previous post.

    We are talking about Composition Dependent values for A2 vs T. The correct Expectation is -.17028 for this hand. We are assuming that the correct action is taken for all downstream hands within the player decision tree.
