Stop and go
Definition of stop and go
A stop and go is a game that a player makes in sit and go or in a tournament. The purpose of a stop and go is to maximize his folding equity when there are shortstack. For example, a player has 11 big blinds and is on big blind. The player in the button position makes a pre-flop raise to 3 big blinds. Rather than pushing all in preflop to 11 big blinds and having a limited folding equity, the player who makes a stop and go will call the preflop bet and push all in on any flop.
Why is the stop and go effective?
Most of the time in poker, you miss the flops. With 2 cards that are not a pair, you hit flop 1 time out of 3. Therefore, the player who makes a stop and go knows that most of the time, his opponent will have to fold. And often, the player who hits stop and go will make the opponent fold a better hand. Imagine that you have JT. The player in the button position opens a pair of 2's. You call the bet and push all in to flop on A7Q. The player with a pair of 2's will not be able to call the bet. The player with JT will have folded a better hand.
