Heads-Up Poker (HU) — 1 on 1

The most important change: the Button posts the Small Blind and acts first preflop, last postflop. The BB acts last preflop, first postflop. This is the opposite of 6-max/9-max.

What does this mean? The Button is an aggressive position. It opens 70%+ of hands — anything with potential.

• Button (SB): Raise 70-85% of hands. Fold only truly weak hands: 72o, 62o, 52o.
• Big Blind vs Open: 3-Bet ~15-20%, Call ~40%, Fold ~40%.
• vs Limper: Iso-Raise very wide — 40%+ of hands.

• High C-Bet: In HU the opponent misses the flop ~65% of the time. Small C-Bet (33% of the pot) on many boards prints money.
• Double Barrel: If the C-Bet worked and the turn card continues the story — keep firing.
• Range Betting: On boards good for your range, you can bet your entire range.
• Adjust fast: If the opponent calls light — stop bluffing. If they fold light — bluff more.

• Calls a lot preflop? Value bet wide, less bluffing.
• Folds a lot to C-Bet? C-Bet 100% on dry, unconnected boards.
• Aggressive back? Trap with strong hands, fold marginal hands that don\'t feel right.

Assume a 100bb stack. You open to 2.5bb from the Button with 92 offsuit — a clear fold in 6-max. The BB folds 45% of the time. Immediate EV from the fold = 0.45 × 1 (SB already in pot) = 0.45bb. Even if called, you have 40%+ raw equity against the BB's wide range, so the raise remains cumulatively +EV.

By contrast, the identical open from UTG in a 9-max game against 8 players behind is a clear fold — every extra player reduces both fold equity and raw equity.
