Proposition ( poker )

1) An offer by one player to another to play under certain circumstances, usually more favorable to the other player, in exchange for calling a bet. Propositions are found mainly in no-limit lowball games. For example, one player raises. The player who opened the pot asks, "Two-for-one?" He is offering a proposition, which is, in effect, saying, "I need to draw two cards to this hand. I would not normally call your raise, but you look like a sporting fellow, so I will call and draw two cards if you agree that you will take one card. If you have to break a pat hand to comply, then so be it; I will not play otherwise." Gentlemen do not offer a proposition and then renege. In other words, if you offer, for example, two-for-one, it's not considered sporting to then draw only one or stand pat after the other has thrown his card, nor is it sporting on his part to accept and then stand pat. (Of course, he could accept and draw two, because that is more of a gamble than the offerer of the proposition was requesting or expecting.) If someone offers you a proposition, naturally you can decline. Again, the sporting thing to do in this example is not to say, "Oh, I'm probably drawing anyway," and then stand pat. If you don't want to give away anything about your intentions, you can say, "Just call the bet, or throw away your hand," or say nothing. Just don't out-and-out lie. While permitted, it's not sporting, and will lose you respect and action later. A counter proposition (described under pass for a prop) is also a possibility.
2) An agreement between two or more players to always take part in a certain gamble when circumstances warrant, such as open blind, raise blind or two-three.
