4 bet是什麼意思

"4 bet" is a term used in poker, specifically in no-limit hold'em, to describe a re-raise that occurs after an initial raise and a re-raise (a three-bet). It essentially means the fourth player to act has raised, following three previous actions: a raise, a re-raise, and a re-re-raise.

Here's a scenario that could lead to a 4 bet:

1. Player 1 opens the betting with a raise.
2. Player 2 re-raises, which is a three-bet.
3. Player 3, who has position on both players 1 and 2, decides to re-raise again, which is a 4 bet.

The number of bets refers to the number of times the pot has been raised. In this context, "bet" refers to an increase in the size of the bet, not a general bet as in "I bet you can't do it."

In poker, understanding and effectively using the 4 bet (and other bet sizes) is a strategic element that can help to deceive or outmaneuver opponents, based on the strength of one's hand and the perceived strength of opponents' hands. It's a way to leverage the dynamics of the game to gain an advantage.
