Heads-Up SNG Strategy

Overview

Heads-up SNG strategy is specifically designed for Sit and Go tournaments involving only two players. Unlike full-ring or short-handed tables, heads-up SNGs have only two players, blind levels typically rise quickly, and every hand determines the outcome. The core of the strategy lies in quickly adapting to the opponent's style and maximizing marginal advantages.

Core Principles

• Aggressive Exploitation: Position is more critical in heads-up play. The button (small blind) should raise frequently (about 70%-80% of hands), while the big blind needs to defend with a wider range.
• Pot Control: Due to shallow stacks (usually starting with around 1500 chips and rapidly escalating blind levels), avoid marginal bets in large pots and prioritize stealing blinds.
• Range Adjustment: Hand values shift upward. Small pairs, suited connectors, etc., are easier to play post-flop; high cards (like A, K) require caution regarding kicker issues.
• Post-flop Play: The flop often decides the outcome in heads-up. C-bet frequency is high, but attention must be paid to opponent's fold rate; slow-playing should only be used with the strongest hands (e.g., the nuts).

Key Stages

Early Stage (Low Blinds)

• Stack depth around 20-30 BB; can play loose-aggressive while observing opponent's tendencies.
• Avoid large bluffs and keep pots small.

Middle Stage (Blinds Increase)

• Stack depth 10-15 BB; tight-aggressive strategy is more effective. All-in ranges should include pairs, A with medium kicker, etc.
• Stealing and re-stealing blinds become primary profit sources.

Late Stage (Short Stack)

• Stack depth 5-10 BB; push/fold strategy dominates. Based on the ICM model (though ICM has less impact in heads-up), focus on opponent's fold rate.

Common Mistakes

• Being too passive: Defending too wide but lacking counterattacks leads to blind losses.
• Neglecting adjustments: Failing to adjust raise frequency based on opponent's looseness or tightness.
• Tilt: The fast pace of heads-up can lead to consecutive losses and poor decisions.

Practice Suggestions

Use heads-up simulation software or practice in low buy-in SNGs, focusing on recording expected value (EV) changes for each hand.
