Overview
UTG (Under the Gun) is the earliest position at the table, with limited preflop actions and vulnerability to attacks from later positions. When a UTG player opens and faces a 3-bet from a later position or the blinds, the UTG player can choose to 4-bet. The key to this strategy lies in constructing a reasonable 4-bet range, considering position, opponent tendencies, and pot odds.
Range Construction
UTG typically employs a tight open-raising range (about 12%-16% of starting hands). When facing a 3-bet, the 4-bet range should primarily consist of value hands and bluffs:
- Value 4-bet: Usually includes AA, KK, QQ, and some AKo/AKs. These hands have a significant advantage against the opponent's 3-bet range and can force opponents to fold or commit more chips.
- Bluff 4-bet: Can use hands with potential for development, such as small suited aces like A5s, A4s, or suited connectors like JTs, T9s. These hands have some playability postflop and help balance the value range.
Sizing and Adjustments
The 4-bet size is typically 2.2 to 2.5 times the 3-bet amount (or 4 to 5 times the initial open). In cash games, effective stack depth affects strategy: with deep stacks (>100BB), you can expand the bluff range; with shallow stacks (≤50BB), you should focus mainly on value hands.
Typical Scenario Example
Assume the UTG player opens to 3BB, and the BTN player 3-bets to 9BB. If the UTG player 4-bets to 22BB, their range might include:
- Value: KK+, AKs (about 1.2% of hands)
- Bluff: A5s, KQs (about 1.0% of hands)
- Total about 2.2% of hands, maintaining a value-to-bluff ratio of approximately 55:45.
Notes
- Opponent Tendencies: Against tight-passive players (rarely 5-bet), you can use more bluff 4-bets; against loose-aggressive players (frequent 5-bets), reduce bluffs and lean toward value 4-bets.
- Position Disadvantage: UTG has a postflop positional disadvantage, so the 4-bet range should be strong enough to avoid being passive in multi-way pots.
- ICM Impact: In tournaments, UTG 4-bet decisions must account for ICM pressure, especially near the money bubble, requiring a reduction in bluff frequency.
