Huge Player Edge
Ibeatyouraces,
First, for the player to get a BJ, his 2nd card must be an X (ten or face). The 8-deck shoe has 8*16 = 128 X's, and since the first card is an Ace, the shoe contains 52*8 - 1 = 415 other cards. Thus, the probability of a player BJ is
Player BJ Prob = 128/415 = 0.3084...
or nearly 31%. Of these BJ's, one-quarter will be suited, and the other three-quarters will not be suited.
To get a High Tie, the player needs the dealer to also have a BJ. Given that the player has a BJ already, the probability of the dealer having an ace + X (in either order) is given as follows:
Ace + X: [(4*8 - 1)/414]*[(16*8 - 1)/413] = 0.02302...
X + Ace: [(16*8 - 1)/414]*[(4*8 - 1)/413] = 0.02302...
Total = 2*0.02302... = 0.04605...
High Tie probability = (Prob of player BJ)*(Prob of dealer BJ) = 0.01420...
Return of High Tie (50) payout = 0.71019...
By the way, the probability of the dealer NOT having a BJ when the player DOES is simply 1 - 0.04605... = 0.9539...
Suited BJ: here, the player must have a suited BJ with the dealer NOT having a BJ. This probability is given as
(1/4)*(0.3084...)*(0.9539...) = 0.07355...
Return of Suited BJ (15) payout = 1.1033...
Unsuited BJ: Here, the player needs an unsuited BJ with the dealer NOT having a BJ. This probability is given as
(3/4)*(0.3084...)*(0.9539...) = 0.2206...
Return of Unsuited BJ (6) payout = 1.3240...
Suited Pair: Here, the player needs one of the seven remaining suited Aces, so the probability is given as
(7/415) = 0.0168...
Return of Suited pair (10) payout = 0.1686...
Unsuited Pair: Here, the player needs one of the 24 remaining suited Aces, so the probability is given as
(24/415) = 0.0578...
Return of Unsuited pair (3) payout = 0.1734...
Total Win Probability = 0.01420... + 0.07355... + 0.2206... + 0.0168... + 0.0578... = 0.3831...
Total Lose Probability = 1 - 0.3831... = 0.6168...
Total Lose Return = -1*0.6168... = -0.6168...
Total Return = 0.71019... + 1.1033... + 1.3240... + 0.1686... + 0.1734... + -0.6168... = 2.8626...
Thus, given that your first card out of the shoe will be an Ace, you have a whopping 186% edge on the High Tie bet.
Go for it! ;-)
