There is an interesting point that I"ve not seen anyone raise yet in that what would be the view of the poker community had he found a similar defect in the cards while playing in a poker tournament. I would hope, and believe he would, have divulged this information to the powers that be to ensure they were not used. However, there may be others that wouldn"t.
Is the moral dilemma different when playing against a faceless casino that has a mathematical edge in every hand played rather than playing against the poker community where there is only a perceived edge.
Also one would think that the reaction from the poker community would be very different if it was the poker community he was "stealing from"
As it was, I for one don"t think that what he did is "cheating", He was using a flaw that he had noticed, not engineered, to obtain an edge against an organisation designed to take your money with a guaranteed edge in the name of entertainment. The casino were also incredibly naive in the sessions where Ivey and his partner were asking for the cards to be turned due to superstition. At no point did Ivey or his partner touch or interfere with the cards in any way.
An interesting case but one where the casino industry finally got their fingers burnt and still managed to close ranks and become the injured party.
