I'll do the math if you tell me which casino has this bet.

Here is the player's IBA as a function of the number of decks used in the game:

Decks IBA
1 -51.669%
2 -26.277%
3 -17.455%
4 -12.972%
5 -10.259%
6 -8.440%
7 -7.137%
8 -6.156%

For an "n" deck game, the probabilities of each outcome are given as follows:
P(4oaK) = [(4n-1)(4n-2)(4n-3)]/[(52n-1)(52n-2)(52n-3)]
P(DT) = [(4n-1)(48n)(4n-1)]/[(52n-1)(52n-2)(52n-3)]
P(ST) = [(n-1)/(52n-1)]{1-[(48n)(4n-1)+(4n-2)(4n-3)]/[(52n-2)(52n-3)]}
P(BT) = [(3n)/(52n-1)]{1-[(48n)(4n-1)+(4n-2)(4n-3)]/[(52n-2)(52n-3)]}
P(Loss) = (48n)/(52n-1)

Applying these formulas to games with various decks gives these values:

Decks IBA 4K (200) DT (40) ST (20) BT (5) Loss (-1)
1 -51.669% 0.000048 0.003457 0.000000 0.055318 0.941176
2 -26.277% 0.000198 0.004433 0.009047 0.054283 0.932039
3 -17.455% 0.000271 0.004771 0.011986 0.053939 0.929032
4 -12.972% 0.000312 0.004942 0.013442 0.053768 0.927536
5 -10.259% 0.000339 0.005045 0.014311 0.053665 0.926641
6 -8.440% 0.000357 0.005114 0.014888 0.053596 0.926045
7 -7.137% 0.000370 0.005164 0.015299 0.053547 0.925620
8 -6.156% 0.000380 0.005201 0.015607 0.053511 0.925301
72 -0.002% 0.000446 0.005433 0.017514 0.053283 0.923324
73 0.009% 0.000447 0.005433 0.017518 0.053282 0.923320

Note that if you can find that rare 73-deck game, you'll have an edge off-the-top ;-)

Also, avoid that single-deck version ;-)

Hope this helps!

So, on the off chance someone puts this in a CSM... Hmmm...

prozema,

Sorry, it doesn't work that way.

For the CSM to simulate an infinite-deck game, you'd need to draw a card, record it, then place it back in the CSM before drawing the next card: then you'd have the equivalent of an infinite-deck game.

Otherwise, whether the game is dealt from a CSM or a shoe has no effect on the IBA.

Sorry to burst your bubble... but think of the $ I just saved you ;-)
