[M.B.E.]

I agree with SossMan about what the ruling should have been (stern warning etc.)

I don't find the actual ruling (hand dead and player gets his chips back) too surprising. It would be ludicrous to rule the hand dead and the chips forfeited.

I like the TDA rule. People expose cards by mistake all the time, and it is far too harsh to kill their hand after they may have invested a huge amount in the pot.

Consider this example: on the turn the pot is headsup and the first player makes a large bet. The second player has a royal flush and says "I call" then turns his hand face up. The second player mistakenly believed that the first player was all-in, but actually the first player had a few chips left. Does anyone really believe that the rules should provide for the royal flush to be ruled a dead hand in this scenario? And if so on what logic?
