Five-Minute Rule poker
A house rule that a player must act on his hand within five
minutes, or else give up the hand and have no claim on the pot.
This rule is found mainly in no-limit games, and is usually
invoked on players who frequently abuse the time limits, that
is, when confronted with a large bet, often study the situation
for long periods of time. The two-minute rule is similar, though
not as common.
