A big bet (BB) is the larger of two fixed bet amounts in a fixed-limit poker game. A big bet is used in the final rounds of a game to increase the pot amount and thereby enable the possibility of a bluff. Big bets are generally double the wager of the initial or small bet.
Prop betting seeks to proposition the bettor with a question, one that may or may not have a direct bearing on the final score. For example: How many receiving yards will Tyreek Hill have?
