5-card draw

Five-card draw (also known as a Cantrell draw) is a poker variant that is considered the simplest variant of poker, and is the basis for video poker. As a result, it is often the first variant learned by new players. It is commonly played in home games but rarely played in casino and tournament play. The variant is also offered by some online venues, although it is not as popular as other variants such as Seven-card stud and Texas hold 'em.

In casino play the first betting round begins with the player to the left of the big blind, and subsequent rounds begin with the player to the dealer's left. Home games typically use an ante; the first betting round begins with the player to the dealer's left, and the second round begins with the player who opened the first round.

Play begins with each player being dealt five cards, one at a time, all face down. The remaining deck is placed aside, often protected by placing a chip or other marker on it. Players pick up the cards and hold them in their hands, being careful to keep them concealed from the other players, then a round of betting occurs.

If more than one player remains after the first round, the "draw" phase begins. Each player specifies how many of their cards they wish to replace and discards them. The deck is retrieved, and each player is dealt in turn from the deck the same number of cards they discarded so that each player again has five cards.

A second "after the draw" betting round occurs beginning with the player to the dealer's left or else beginning with the player who opened the first round (the latter is common when antes are used instead of blinds). This is followed by a showdown, if more than one player remains, in which the player with the best hand wins the pot.

Variants of the five-card draw are often considered to be the most difficult poker games to master psychologically, due to the fact that no cards are open and that bluffs (or semibluffs) occur naturally at the draw of new cards. Players must pay attention to how many cards other players change, but should not take too much for granted in this phase. Psychology is a major factor when drawing cards. For instance it is not always advisable to draw three new cards when holding a pair, although this is statistically the best way to improve the rank of the hand. The reason is that the other players quite easily can "read" the hand. A player may choose to draw one or two cards instead in order to make other players believe that the hand is better than it really is.
