Post Oak Bluff

1. A very small bet relative to the size of a pot.

Explained

This type of bluff is often used as an attempt at reverse psychology to steal the pot. It holds little risk for the player making the bet. Basically, an opponent will see you make such a small bet into a big pot and think you are begging for a call and then think they are making a big laydown when they fold.

Origin

This term was popularized by Doyle Brunson in his 1979 book Super/System.

Example

A player that wants to pull off the "Post Oak Bluff" will bet a small amount relative to the size of the pot, typically just 10%. By doing this he mimics the play of someone that has an absolute monster hand that wants a call. Mathematically, this bet only needs to be successful one-tenth of the time to work. Often times in modern online poker, this is seen as a weak play and raised by solid aggressive players.
