A 3bet is the third bet in a betting sequence — the blind/limp is the 1bet, the open raise is the 2bet, and the re-raise is the 3bet. Pre-flop it is widely used for value with premium holdings and as a bluff with select hands. A balanced 3bet range contains strong hands and bluffs in appropriate proportions to avoid exploitation. Position plays a critical role in constructing 3bet ranges.
