PFR from CO

Overview

PFR from CO is a key statistical metric in poker tracking software (e.g., PokerTracker, Hold'em Manager) that measures how often a player raises first in when in the cutoff position. It is a subset of the broader PFR (Pre-Flop Raise) stat, which tracks all raises regardless of position. The cutoff (CO) is one of the most profitable positions because it acts after the hijack and before the button, allowing aggressive play to steal blinds and exploit weaker ranges.

Typical Range and Strategy

A solid PFR from CO typically ranges from 20% to 30% at 6-max tables, expanding to 25%–35% in more aggressive games. Common opening hands include all pairs (22+), suited aces (A2s+), broadways (ATo+, KJo+, QJo+), suited connectors (54s+), and some suited one-gappers. The exact range depends on table dynamics and opponent tendencies. Players often open wider from CO because they have only two players (button and blinds) left to act, and can profitably steal blinds with a wider range. Against tight blinds, a player might raise with 40%+ of hands; against aggressive 3-bettors, they tighten up.

Importance in Position

Position is one of the most critical factors in poker, and CO is the second-best seat after the button. Raising from CO allows the player to control the pot size and dictate the flow. If the button folds, the CO player has position on the blinds, which is a significant advantage. A high PFR from CO indicates an aggressive, position-aware player who exploits late-position opportunities. Conversely, a low PFR from CO might suggest a passive style or a player who over-folds non-premium hands.

Adjustments Based on Opponents

• vs. Tight 3-bettors: Open wider to exploit their folding range; if 3-bet, fold or 4-bet selectively.
• vs. Loose 3-bettors: Tighten your opening range and use more 4-bets or traps.
• vs. Calling Stations: Open a strong value range and bet for thin value post-flop.
• vs. Weak Blinds: Steal aggressively with a wide range, as blinds often fold too much.

Related Concepts

• VPIP: Voluntarily Put Money In Pot; includes all calls and raises. PFR from CO is a subset.
• 3-bet: A re-raise after a raise; a high PFR from CO may invite more 3-bets from the button or blinds.
• Steal: Raising from late positions (CO, BTN) to steal blinds; PFR from CO is a primary steal tool.
• Cutoff vs. Button: The button has even better position, so CO openings are slightly tighter than button openings but wider than hijack.

Limitations

PFR from CO should not be viewed in isolation. Sample size matters: at least 100-200 hands per position are needed for reliability. Also consider game type (6-max vs. full ring), stack depths, and tournament ICM pressure. A high PFR from CO in a cash game may be standard, but in a tournament with large blinds, it could represent a push-or-fold strategy.

In summary, mastering PFR from CO involves balancing aggression, position awareness, and opponent exploitation to maximize profit from one of the most valuable seats at the table.
