翻牌前4-bet（Flop 4-Bet）

Overview

Flop 4-Bet refers to the fourth raise action in the preflop betting sequence. The standard preflop sequence is: blinds (0-bet) → open raise (2-bet) → 3-bet → 4-bet. Flop 4-Bet typically occurs before the flop is dealt and is the final raise in the preflop betting phase (unless there is a 5-bet or further action).

Strategic Significance

• In Texas Hold'em, a 4-bet usually represents very strong hands such as AA, KK, or AKs, but can also be used as a bluff (e.g., small pocket pairs, AXs). Flop 4-Bet is a key move to seize initiative and narrow the hand range.
• Position is a key factor. 4-betting in position (e.g., on the button) is more common because it allows control over postflop pot size. 4-betting out of position (e.g., from the big blind) requires stronger hands or a clear bluff plan.
• Frequency relates to opponent tendencies. Against opponents who 3-bet frequently, increasing 4-bet frequency can punish their aggression; against tight-passive opponents, reduce 4-bet bluffs.

Common Misconceptions

• Some players mistakenly think "Flop 4-Bet" refers to the fourth raise on the flop (i.e., flop bet → raise → 3-bet → 4-bet), but in standard terminology, raises after the flop are usually called "raise" or "2-bet", not "4-bet". In the industry, "4-bet" almost exclusively refers to the fourth raise preflop.
• If a similar sequence occurs on the flop, a more accurate description would be "fourth raise on the flop" or "Flop 4-bet (non-standard)", but to avoid confusion, it is recommended to use phrases like "re-raise of a flop bet".

Summary

Flop 4-Bet is an important tool in aggressive preflop play; when used correctly, it can effectively build the pot or force opponents to fold. Mastering its applicable scenarios, range construction, and opponent adjustments is key to improving preflop strategy.
