What is 4-Bet in poker?

A 4-bet represents the fourth bet in a sequence: an initial open-raise (2-bet), followed by a 3-bet (re-raise), and then a 4-bet. This powerful move significantly commits chips and often implies a very strong hand. A well-constructed 4-betting range typically consists of premium value hands like QQ+, AK, designed to extract maximum value. It also includes selected bluffs, such as A5s or KQs, to prevent your range from being too transparent and to apply pressure on opponents who 3-bet too widely. Correct sizing and range balance are crucial for effective 4-betting.

UTG opens to 3BB, the CO 3-bets to 9BB, and the BTN 4-bets to 22BB, putting significant pressure on the original raiser and the 3-bettor.
