Hi everyone, poker dealer, part time poker player and maths graduate here. Just registered cos this story has really got me interested. Also, the gambling probability analysis on this thread is on the whole
terrible.
Feeble Gimmick pretty much nailed it with his post on page 25:

Assume 30s / hand over 7 hrs = 840 hands
=> need probability of winning at least 444 (losing 396)
Using a binomial calculator with p = 0.4947, n = 840, x = 444, the probability of winning at least this much is 2.7%.
I guess the chance of doing this without going busto first is a bit lower, but who can say if he would have rebought.
If youre analysis as to Iveys probability of winning £7.3m is fundamentally different (i.e. not based on the number of hands and the binomial theorem) then please, go away and learn some probability theorem.
The key thing to Iveys % probability of winning that much is that it varies quite heavily depending on how many hands he played. As someone else pointed out, if he played 420 hands total (1 a minute) instead of 840 (2 a minute), he probability of winning over £7.3m goes down from 2.7% to 0.6%.
If he played 2000 hands - thats 1024 wins, 976 losses - his probability of winning goes up to 6.9% (I am using Feeble Gimmick's
binomial calculator here).
Ultimately we don't know how many hands he played. 30s a hand sounds quite possible to me. I would guess he played somewhere between 420 and 840 hands.
Either way, the probability of this huge win is obviously small, but
not suspiciously insignificant . Sounds like the casino are just being whiny little bitches. I don't see really how he could have cheated. (Note: the smaller period of playing £50k/hand won't effect the odds much)
Ultimately though, our calculations are based on little information and alot of speculation. We don't know how many hands he played. We don't know what his stakes were for each hand. We don't know wether he backed 'banco' every time of did some of the other bets available on punto banco.
I have heard that you can also 'count' on punto banco to gain a small edge, the same way you can count on shoe blackjack . Is it possible Ivey did this? Suppose he
did. Card counting is not against the law, it is just against house rules. Would Crockfords have to pay him if they could prove it?
My gut feeling is just that Ivey hit a sick run and Crockfords are being little bitches. And hopefully, will lose alot of custom for behaving like this.
/rant!
