Standard Draw Poker

This game is played as described in Draw Poker, and the player who makes the first bet does not need any minimum hand in order to bet. In other words, he can open the betting without even a pair. Once the betting round is complete and players have drawn their cards, the second betting round begins and the first hand again has the opportunity to bet.

Some players vary this game slightly by playing a "blind opening", whereby the first hand must open the pot and (usually) the next player must raise. This game is played "pass and out" (described in Draw Poker) before the draw, but usually "pass and back in" after the draw. This is the form of Poker played in private clubs when Draw Poker is selected instead of Stud. A variant of the blind opening is English or Australian Poker, in which a player who raises can double the preceding bet. (Raising in this game is often called "doubling".)
