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:
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.
