Player Types and Exploits
Villain types, player reads, population tendencies, exploitative adjustments, and opponent profiles.
Aggressive Regular
An aggressive regular prefers betting and raising over calling to seize initiative and control pots. In No-Limit Texas Hold'em, where players may wager any portion of their stac...
Aggression Factor
Aggression factor (AF) is the ratio of a player's postflop bets and raises to their calls, displayed on a HUD next to VPIP and PFR. It tells you whether someone pressures pots o...
Calling Station
A calling station is a highly passive player who calls bets frequently instead of raising or folding. They rarely bluff (a bluff is a bet with a weak hand meant to make opponent...
Calling Station Profile
A calling-station profile is the evidence bundle (notes, HUD numbers, and showdown receipts) that earns an opponent the calling-station label: high VPIP, low aggression, low fol...

Exploitative Play
Exploitative play means deliberately leaving a balanced baseline to attack a specific opponent's leak. It is the highest-EV move when you have a real read; it is also the move t...
HUD
A HUD (Heads-Up Display) is an overlay for online poker that shows tracked stats next to each opponent: VPIP, PFR, aggression, fold-to-c-bet, and others. Treat the numbers as si...
LAG
A LAG (loose-aggressive) player enters more pots than the table average and bets, raises, and re-raises at a higher frequency than a balanced regular. The style trades hand-stre...
Loose-Aggressive
Loose-aggressive is the long-form name for the style most players know as LAG: a player who enters more pots than the table average and applies pressure with bets and raises rat...
Loose-Passive
A loose-passive style enters more pots than the table average and, once involved, leans on checks and calls instead of bets and raises. The label is broader than calling station...
Maniac
A maniac is an extremely loose-aggressive player who enters far too many pots and applies pressure on every street without the hand selection or postflop discipline of a control...
Nit
A "Nit" is an extremely conservative poker player who plays very few hands. They fold most situations unless holding premium hands, like big pocket pairs (A♠A♦) or strong broadw...
Opener Profile
The opener is the first player to bet or raise in a betting round, initiating action. That opening move sets the hand's dynamics, gives opponents information, and forces respons...
PFR
PFR (Preflop Raise Percentage) is the share of hands a player raises before the flop, counting both opens and three-bets. It is the cleanest single read on preflop initiative. P...
Player Read
Player reads estimate what an opponent likely holds and what they'll do next. A read combines observable behavior, betting history, and table position to reduce uncertainty. Tha...
Population Exploit
A population exploit intentionally departs from Game Theory Optimal (GTO) strategy to profit from common mistakes across the player pool. GTO aims to be unexploitable. When most...
Population Line
The population line summarizes the aggregate tendencies of the average player pool, not reads on a single opponent. It describes how a typical player at a given stake acts - for...
Population Tendency
A statistical habit shared by most players in a pool, like overfolding to 3-bets. Persistent and exploitable, even when individual reads are thin.
Regular
Quick review of mechanics shaping regular play:
Rock
A rock is a very tight, risk-averse player who enters very few pots and usually shows up with strong holdings when they do continue. The label is a table read built from repeate...
Sizing Tell
A sizing tell is information inferred from a player's bet-size pattern when the size they pick correlates with strength, weakness, protection, or uncertainty. It is not the stra...
Sticky Caller
A sticky caller habitually calls bets and rarely folds under pressure. In No-Limit Hold'em-where players may wager any or all chips-this tendency costs the caller and becomes ex...
TAG
TAG (tight-aggressive) is a player profile that enters fewer hands than average but raises or bets when they do enter. Tight selection plus active aggression is the textbook 6-m...
Table Image
Table image is the way opponents perceive your style based on what they have seen you do — hands shown at showdown, bet sizes, the speed of your actions, and how often you've re...
Tell
A tell is a physical, behavioral, timing, or betting cue that may reveal information about an opponent's hand strength, confidence, or decision process. Tells are noisy. Treat a...
Tight-Aggressive
Tight-aggressive is a poker player style that enters a selective range of hands and tends to raise or bet instead of limping or calling. The shorthand is TAG, which most coachin...
Tight-First
"Tight-first" means you play fewer hands and focus on strong starting cards. Fold marginal or speculative holdings-hands that depend on specific flops, like small suited connect...
Timing Tell
A timing tell is information you infer from how quickly or slowly an opponent acts. Snap-checks, snap-calls, long tanks, quick bets, and delayed raises can all hint at hand stre...
Villain
The Villain is the opponent the Hero (the player in focus) analyzes in a hand. The Villain can be a real seat at the table or a hypothetical opponent used to explore decisions....
VPIP
VPIP (Voluntarily Put Money In Pot) is the percentage of hands a player chooses to enter preflop by limping, calling, or raising. It excludes forced blinds and free walks. VPIP...
Weak-Tight
Weak-tight is a player-read shorthand for a tight, low-pressure style: the opponent enters few hands, then gives up too easily once a pot starts heating up. Bets, raises, or any...
WTSD
WTSD (Went To Showdown) is the percentage of hands a player takes to showdown after they have seen the flop. It signals how often someone folds turns and rivers versus how often...
