Cutoff: The Second Strongest Position in Texas Hold'em

The cutoff (CO) is to the right of the button. It is the only seat that can always act before the button postflop and still have the last raising privilege (except for the button itself). Because the CO player has position over all blinds and later positions postflop, and can effectively isolate the blinds, the CO's opening range should be wider than early position but slightly tighter than the button.

Basic Opening Range: Varying Blind Defense Tendencies

1. Passive Blinds (Few 3-bets, Few Calls)

When the blinds have a high preflop fold rate and rarely 3-bet, the CO can open-raise frequently to steal. A typical range includes:

• Value raises: All pairs (22+), all suited connectors (54s+), all AXs (A2s+), AJo+, KQo, KJs+, QJs+
• Steal raises: The range can expand to about 40-50% of hands, including T9o, JTo, QTo, all suited gappers (K9s, Q9s, J9s, T8s, 98s, 87s, etc.), some medium-low offsuit connectors (T8o, 98o)

Example: CO holds K9s, blinds are loose-passive. Raise 2.5-3 BB, expecting blinds to call or fold.

2. Aggressive Blinds (Frequent 3-bets, Wide Call Range)

If the blinds are good at 3-bet bluffing and have a wide calling range, the CO should tighten the opening range and mix in more limping.

• Raise range: About 15-20% strong hands, including TT+, AQo+, AJs+, KQs, ATs, A5s (for balance)
• Limp range: Small to medium pairs (22-TT), suited connectors (54s-T9s), A2s-A9s, KTs+, QTs+, JTs – these hands have postflop potential and avoid getting 3-bet too often.

Note: Against aggressive blinds, avoid raising hands like KJo, QJo, ATo that are vulnerable to reverse implied odds.

Effect of Stack Depth on CO Opening Range

1. Deep Stacks (150BB+)

Deep stacks allow for more complex postflop play. The CO can slightly widen the range, especially suited connectors and gappers, to realize showdown value or bluff postflop. However, be careful not to build huge pots against big stacks.

• Can add A2s-A5s (for small-pair bluffs), all suited connectors (54s+), suited gappers (T8s, 97s, etc.)
• Reduce hands like KJo, QTo that are easily dominated.

2. Medium Stacks (Around 100 BB)

Standard situation – use the basic range.

3. Short Stacks (30-50 BB)

Short stacks have limited postflop maneuverability. Prioritize strong hands and avoid entering pots with weak hands.

• Raise range: TT+, AQo+, AJs+, KQs, ATs, A5s
• Shove range: Medium pairs (88-99), AXs (A8s+), KQo (some situations)
• Fold: All offsuit connectors, small pairs (22-77) unless a special steal opportunity arises.

Strategy Against Different Positions' Raises

The CO faces opponents from early position (UTG, MP), the CO itself, the button, and the blinds.

Early Position Raises (UTG, MP)

When facing an early position raise, the CO should use a tight and focused response range:

• 3-bet for value: KK+, AKs, AKo (about 3% of hands)
• Call: JJ, TT, AQs, AQo, AJs, KQs (about 5% of hands), plus some small-medium pairs (99-88) and hands with straight potential like TJs, QJs.
• Fold: All other low-quality hands.

Button Limp or Raise

When the button limps, the CO can expand the raise range to 60%+ but must watch for button traps. If the button is loose-aggressive, consider checking to raise and steal the pot.

Blind 3-bet

After the CO opens and a blind 3-bets:

• 4-bet for value: AA, KK, AKs (about 1% of hands). Deep stacks can add QQ, AKo, A5s (as a 4-bet bluff).
• Call: JJ-99, AQs, AQo, KQs, some suited connectors (T9s, 98s).
• Fold: All other hands, including ATo, KJo, small pairs.

Postflop Play Framework

The CO's postflop advantage lies in position – use it fully.

• Continuation Bet (C-bet): Flop C-bet frequency around 50-60%, higher on dry boards (e.g., K72 rainbow), lower on wet boards (e.g., 678 two-tone).
• Double Barrel: After being called on the flop, if the turn is a blank, continue betting to represent a strong hand, especially when your flop C-bet frequency is high.
• Check-Call: With draws or medium-strength made hands, check to control the pot and use position to decide on the river.
• Check-Raise: Flop check-raise is often used against aggressive opponents to represent a very strong hand or a draw.

CO Position Strategy in Tournaments

In tournaments, ICM has a significant impact, so the CO opening range needs adjustments:

• Early Stage (small blinds, deep stacks): Similar to cash games, but slightly tighter to avoid marginal confrontations.
• Mid Stage (large blinds, M-value 15-25): Tighten the raising range to about 15-20% of strong hands to avoid getting in trouble after a 3-bet.
• Bubble Period: The CO should be more conservative, especially when big-stacked players are in the blinds; the value of stealing with small pairs and suited connectors decreases, while strong hands (e.g., AQ+) can still be raised.
• Near the Money: If the CO has a medium stack, you can frequently shove to steal blinds, with a range including AXs, small to medium pairs, KQs, etc.

Common Mistakes and Adjustments

• Mistake 1: Raising with a wide range when the blinds are aggressive.
  • Adjustment: Tighten the raising range, increase limping and folding.
• Mistake 2: Folding too often against opponents' 3-bets.
  • Adjustment: Call or 4-bet appropriately based on opponent tendencies, but overall fold rate should remain above 60%.
• Mistake 3: Postflop continuation betting too linearly.
  • Adjustment: Mix betting, check-calling, and check-raising to make it difficult for opponents to read your range.

Mastering the CO opening range and continuously adjusting based on dynamics is key to improving profitability. Remember, position is one of the biggest advantages in Texas Hold'em; using the CO effectively will become a powerful weapon in your arsenal.
