Call: A player may call a bet by putting an amount of money exactly equal to the bet into the pot. For example, if Tony bets $2, and Brian wants to call Tony’s bet, Brian must put $2 into the pot.

Fold: A player may fold his hand by laying down his cards, and forfeiting further play in a round of poker. For example, if Tony bets $2 and Brian wishes to fold, Brian must surrender his cards to the dealer, and will remain inactive for the rest of the round.

Raise: A player may raise a previous bet by putting an amount greater than the bet into the pot. A raise must be at least double the size of the previous bet. For example, if Tony bets $2, and Brian wants to raise Tony’s bet, Brian may put $4 or more into the pot.

Check: A player may pass his turn in a round of poker without taking any betting action, only if there are no previous bets in the round. This is known as a check. For instance, if Brian is first to act on the flop in a hand, he has the option of checking his hand, which will put the action on the next player.
