关煞位偷盲范围（Steal Range from Cutoff）

Overview

The Cutoff (CO) is the position immediately before the Button and the last non-blind position that can attempt a blind steal. Since the Button has positional advantage postflop, the Cutoff's blind-stealing strategy must balance aggression with defense.

Factors in Blind Stealing Range

• Positional Advantage: The Cutoff only faces the Button, Small Blind, and Big Blind. If the Button folds preflop, the Cutoff retains positional advantage postflop.
• Table Dynamics: If the blinds fold frequently, widen the starting hand range; tighten it if they defend aggressively.
• Stack Depth: With deep stacks, the range can be wider to include speculative hands; with short stacks, prioritize high cards or pairs.
• Opponent Tendencies: Be more aggressive against tight-passive players; cautious against calling stations or frequent 3-bettors.

Typical Range Examples (6-max standard)

• Aggressive: About 25%-30% of starting hands, including all pairs (22+), all Ax suited (A2s+), high cards (K9s+, Q9s+, J9s+), some suited connectors (54s+), and a few offsuit broadways (KTo, QTo, etc.).
• Conservative: About 15%-18%, such as all pairs (22+), A8o+/A5s+, K9s+/KJo+, Q9s+, JTs+.

Adjustment Strategies

• Against tight-passive blinds: Widen the range, even stealing with marginal hands.
• Against frequent 3-bettors: Reduce medium-strength hands, increase strong hands, and consider 4-betting.
• Against calling stations: Raise for value, reduce bluffs.

Considerations

Cutoff blind-stealing requires balance: being too wide invites re-steals or 3-bet punishment; being too tight forfeits opportunities. Strong players dynamically adjust their range based on real-time information.
