On the Come ( poker )

1) Describing a bet made on an unmade hand before all the cards have been dealt, or in the anticipation of making a hand. In lowball, this is usually whatever you're drawing to; in high (draw, stud, or hold 'em), it is usually four cards to a straight, flush, or straight flush. To raise on the come means to start with four cards to a good hand that is not yet made, and raise the pot before the draw to build a larger pot, with the hope of making the hand and having a larger pot to bet into after the draw. A player who starts with A-2-3-4-K in lowball and raises is raising on the come. To bet on the come usually means to bet as just described; sometimes to make a blind bet after the draw after having drawn one card to a come hand. (A come hand is a hand that needs one card on the come.)
2) A hand that is drawing to a straight or flush.
