Ken Churchill Receives a One-Orbit Penalty
Rule #31 of the TDA states: A player who exposes his cards with action pending may incur a penalty, but will not have a dead hand. The penalty will begin at the end of the hand.
According to Churchill, one of the tournament directors was standing over his shoulder and witnessed him expose his hand before making the call, subsequently issuing the penalty. Churchill told us that he made the call and lost the hand; he has since returned to his table.
