Exposed Hands and Penalties
The rule at the 2010 World Series of Poker is that if you expose your hand at any point with pending action, you will receive a penalty of one round.
Over on Table 283, the floor was summoned because a player mistakenly exposed his hand after the second draw of deuce-to-seven. The hand was completed and then the player who turned over his hand before he was supposed to was issued a penalty of one round. On the very next hand, another player did the same thing and the floor was summoned again to issue the penalty. What makes this funny is that the player who exposed his hand the second time around was the opponent of the player who exposed his hand in the first one.
