A poker player is drawing if they have a hand that is incomplete and needs further cards to become valuable. The hand itself is called a draw or drawing hand. In contrast, a made hand already has value and does not necessarily need to draw to win. A made starting hand with no help can lose to an inferior starting hand with a favorable draw.
Not only draws benefit from additional cards; many made hands can be improved by catching an out — and may have to in order to win. An unseen card that would improve a drawing hand to a likely winner is an out. Playing a drawing hand has a positive expectation if the probability of catching an out is greater than the pot odds offered by the pot. A dead out is a card that would normally be considered an out for a particular drawing hand, but should be excluded when calculating the probability of catching an out.
Outs can be dead for two reasons:. A flush draw , or four flush , is a hand with four cards of the same suit that may improve to a flush. A flush draw has nine outs thirteen cards of the suit less the four already in the hand. An outside straight draw , also called up and down , double-ended straight draw or open-end ed straight draw , is a hand with four of the five needed cards in sequence and could be completed on either end that may improve to a straight.
An outside straight draw has eight outs four cards to complete the top of the straight and four cards to complete the bottom of the straight. Straight draws including an ace are not outside straight draws, because the straight can only be completed on one end has four outs. An inside straight draw , or gutshot draw or belly buster draw , is a hand with four of the five cards needed for a straight, but missing one in the middle.
An inside straight draw has four outs four cards to fill the missing internal rank. Because straight draws including an ace only have four outs, they are also considered inside straight draws. The probability of catching an out for an inside straight draw is half that of catching an out for an outside straight draw.
A double inside straight draw , or double gutshot draw or double belly buster draw can occur when either of two ranks will make a straight, but both are "inside" draws. The probability of catching an out for a double inside straight draw is the same as for an outside straight draw. Sometimes a made hand needs to draw to a better hand. For example, if a player has two pair or three of a kind , but an opponent has a straight or flush, to win the player must draw an out to improve to a full house or four of a kind.
There are a multitude of potential situations where one hand needs to improve to beat another, but the expected value of most drawing plays can be calculated by counting outs, computing the probability of winning, and comparing the probability of winning to the pot odds.
A backdoor draw , or runner-runner draw , is a drawing hand that needs to catch two outs to win. For example, a hand with three cards of the same suit has a backdoor flush draw because it needs two more cards of the suit. Backdoor draws are generally unlikely; with 43 unseen cards, it is equally likely to catch two out of seven outs as to catch one out of one. A player is said to be drawing dead when the hand he hopes to complete will nonetheless lose to a player who already has a better one.
For example, drawing to a straight or flush when the opponent already has a full house. In games with community cards , the term can also refer to a situation where no possible additional community card draws results in a win for a player. From Wikipedia, the free encyclopedia.
