VPIP

VPIP stands for voluntarily put in pot. It is the percentage of hands in which a player chose to invest money before the flop — the single most basic measure of how loose or tight someone plays.

Full-ring regulars run around 15–22% VPIP, six-max regulars 22–28%, and recreational players anything from 35% upward. Read together with PFR it tells you the style: a big gap between VPIP and PFR means a passive caller, a small gap an aggressive player.

What counts and what does not

The key word is voluntarily. Posting the small or big blind does not count, because the player had no choice. Calling, raising or re-raising pre-flop does count. A hand in which the big blind is simply walked — everyone folds and no money is added — does not.

That definition is why VPIP tops out well below 100 per cent even for extremely loose players, and why it is a clean measure of decisions rather than of circumstances.

VPIP alone says very little

The stat is read next to PFR — pre-flop raise percentage — and the gap between the two is where the information is. VPIP describes how often a player enters a pot; PFR describes how often they do it aggressively. The same VPIP produces very different players depending on the gap:

- A small gap means an aggressive style: almost every hand played is raised rather than called. - A large gap means a passive, calling-heavy style. A player with a high VPIP and a PFR far below it is limping and calling a great deal, which is the classic weak profile. - Both numbers low describes a tight player who only enters with strong hands, and raises when they do.

Sample size is the usual mistake

VPIP stabilises faster than most statistics because a decision is recorded on nearly every hand, but it still needs volume. Over a few dozen hands a player who has simply been dealt good cards looks loose and one who has been dealt nothing looks tight. A read drawn from a very small sample is mostly noise, and acting decisively on it is one of the more reliable ways to lose money to a competent opponent.

The figure also shifts with the game. A player's VPIP at a six-handed table is naturally higher than at a nine-handed one, because there are fewer players to get through, so comparing the same number across different table sizes is meaningless.

Where the number comes from

VPIP is one of the standard readouts in tracking software and in a HUD, calculated from a player's own hand histories. Several jurisdictions and several operators restrict or prohibit HUDs and third-party tracking, and the rules differ between rooms — a player relying on them should check the site's terms rather than assume.

Using it honestly

The useful application is narrow and worth stating plainly: VPIP and PFR together suggest where an opponent's range is likely to be too wide or too narrow, which informs how much to value-bet and how much to bluff. They do not tell you what someone holds in the hand in front of you. Players who treat a HUD readout as a substitute for watching what an opponent actually does with their range tend to be exploitable in predictable ways.
