A popular poker game, and the only variant played at the World Series of Poker. Players are dealt two cards, one at a time. There is a round of betting and then three cards at once come down on the table. This is refered to as the flop, and counts as community cards. That means everyone playing can use those cards as part of their hand. More betting and another card, the turn card. More betting and the last card, the river. Last bets, then finally comes the showdown. Best five card hand wins.
