Free Roll
Poker
One player has a shot at winning an entire pot when he is currently tied with another player. For instance, suppose you have A♣-Q♣ and your opponent has A♦-Q♥. The flop is Q ♠-5♣-T ♣. You are tied with your opponent right now, but are free rolling, because you can win the whole pot and your opponent can't. If no club comes, you split the pot with him; if it does come, you win the whole thing.
