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. For example, in seven-card stud, if four of a player's first five cards are all spades, but the hand is otherwise weak, they are ''drawing to'' a flush. 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. If an opponent has a made hand that will beat the player's draw, then the player is ''drawing dead''; even if they make their desired hand, they will lose. 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. ==Outs== 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.'' The probability of catching an out with one card to come is: : The probability of catching at least one out with two cards to come is: : : 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 dead out may work to improve an opponent's hand to a superior hand. For example, if Ted has a spade flush draw and Alice has an outside straight draw, any spades that complete Alice's straight are dead outs because they would also give Ted a flush. * A dead out may have already been seen. In some game variations such as stud poker, some of the cards held by each player are seen by all players. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Draw (poker)」の詳細全文を読む スポンサード リンク
