4Bet from MP

4Bet from MP

A 4-bet (the fourth raise in a betting round) executed from middle position at the table.

Overview

In no-limit hold'em, a 4-bet is the third raise after the initial preflop raise (the 2-bet). The sequence typically goes: open-raise (2-bet), 3-bet, then 4-bet. "4Bet from MP" specifically refers to making this third raise from middle position (MP) — the seats immediately to the right of the cutoff and hijack. Middle position is considered a neutral-to-tight range area because players still have multiple opponents behind them, including the cutoff, button, and blinds.

Purpose and Strategy

A 4-bet from MP is usually made for one of three reasons: value (with premium hands like AA, KK, QQ, AK), bluff (with hands that have blockers to the opponent's value range, such as A5s or KQo), or occasionally to isolate a loose 3-bettor. Because MP is earlier than late position, the 4-bet range from MP is generally tighter and more polarized than from the button or small blind. A typical MP 4-bet value range might include only AA, KK, and sometimes AKs, while bluff-candidates are chosen from suited aces or high card combinations that block the opponent's possible value holdings.

Sizing and Considerations

Standard 4-bet sizing against a single opponent is usually 2.2 to 2.5 times the 3-bet size, adjusted for stack depths. When out of position (MP is in position relative to the 3-bettor if the 3-bettor is in the blinds, but out of position if the 3-bettor is in late position), sizing may be larger to discourage calls. If stacks are deep (over 100 big blinds), 4-betting becomes more complex because opponents may 5-bet bluff, and MP must be prepared to face a potential shove.

Typical Ranges

A balanced MP 4-bet range in a 100bb cash game might consist of:

  • Value: AA, KK (sometimes AKs, QQ depending on opponent)
  • Bluff: A5s, A4s, KQo (blocking AA/AK/KK)

Against a wide 3-bettor (e.g., from the button), MP can widen the 4-bet range slightly, but must be cautious since players behind can still wake up with strong hands.

Example (Typical Situation)

  • Blinds: $1/$2, effective stacks $200.
  • MP (Hero): Opens to $6 with K♠K♣.
  • Button: 3-bets to $22 (a typical 3-bet).
  • MP: 4-bets to $55 (standard sizing).
  • Button folds or 5-bets. If button calls, Hero proceeds postflop with an overpair.

Summary

4Bet from MP is a powerful but risky move because of the players left to act. It is best used with strong value hands or selective bluffs, balanced against the opponent's 3-bet tendencies. Proper sizing and awareness of stack depths are essential to avoid being exploited.
