VPIP from CO

Concept

VPIP (Voluntarily Put Money In Pot) is a key metric that measures how often a player voluntarily enters the pot, calculated as the percentage of hands in which the player voluntarily bets, raises, or calls (excluding blinds). VPIP from CO specifically measures this frequency when the player is in the Cutoff position (i.e., Under the Gun +1, typically seat 7 at a 9-handed table).

Position Characteristics

The Cutoff is the first favorable position after the gun, with the following features:

• Position advantage: post-flop it is in a middle-to-late position, allowing observation of actions from earlier players.
• Stealing opportunity: when the button folds, the CO can attempt to steal blinds from the small blind and big blind.
• Tight-aggressive players often slightly widen their hand range in this position, but still tighter than the button.

Data Significance

VPIP from CO is an important indicator for evaluating a player's positional strategy differences. A normal aggressive player's VPIP from CO is typically between 20%-30%, a tight-aggressive player about 15%-20%, and a very loose-aggressive player can reach over 35%. If this value deviates significantly from overall VPIP, it may indicate the player is not adjusting properly to position.

Strategic Application

Analyzing an opponent’s VPIP from CO can help formulate counter-strategies:

• Against opponents with high CO VPIP, increase 3-bet frequency and use position to re-raise.
• Against opponents with low CO VPIP, steal blinds or isolate more frequently.
• When in the CO yourself, adjust your entering standards based on the blind players’ styles: if blinds are tight, widen your range; if blinds are loose, tighten your range.

Data Collection

Poker tracking software (e.g., Hold'em Manager, PokerTracker) can provide CO VPIP data from hand histories. It is generally recommended to collect at least 200 hands in that position before the data becomes statistically meaningful.
