[Jive Dadson]

Assuming the cardroom has the rule that the floorman is allowed to remedy unusual situations to protect the integrity of the game ... The floorman should ask seat six to write down what his cards were, and not allow anyone to see it except the floorman The floorman should then instruct the dealer to retrieve them from the muck. If the cards match, play continues. If not, seat six loses everything including the $900 bet, but is allowed to murder the dealer without penalty.

The hard-nosed decision is that seat six loses everything. However, I don't think players should have to be too worried about the dealer stealing their cards from them.
