3-bet
The re-raise over an open: the third bet in the preflop sequence (blind, open, re-raise). A weapon for value and pressure at the same time.

Blockers
Cards in your hand that reduce the combos your opponent can have. Holding an ace makes it half as likely that your opponent has AA.
See example and numbersBluff catcher
A hand that only wins if your opponent is bluffing: it loses to all their value. Calling or folding it is the purest river decision there is.
See example and numbersC-bet
The continuation bet: the preflop raiser bets again on the flop, keeping the initiative — whether they connected or not.
See example and numbersCheck-raise
Checking with the intention of raising when your opponent bets. It turns your positional disadvantage into a trap — and makes automatic c-bets expensive.
See example and numbersEquity
Your share of wins if the hand were played out to the end an infinite number of times. It is the basic measure of what your hand is worth right now.
See example and numbersFold equity
The share of a bet's value that comes from the times your opponent folds. It is what makes betting profitable with hands that are not the best yet.
See example and numbersGTO
Game Theory Optimal: the equilibrium strategy that cannot be exploited, because it mixes value and bluffs in exact proportions. The starting point — not the goal.
See example and numbersICM
Independent Chip Model: converts tournament chips into real prize money. Its core lesson: in a tournament, the chips you risk are worth more than the chips you can win.
See example and numbersJoker
The spare card every deck ships with, and the one Texas Hold'em never uses. The game runs on exactly 52 cards, and that number is what every probability in poker hangs on.
See example and numbersKicker
The side card that breaks ties between two players with the same hand. The silent cause of most "bad luck" hands.
See example and numbersOuts
The cards left in the deck that turn your hand into the winner. Counting them gives you your chance to improve: each out is worth ~4% on the flop and ~2% on the turn.
See example and numbersPosition
Your seat relative to the button, which decides whether you act before or after your opponent. Acting last is the biggest structural edge in poker.
See example and numbersPot odds
The price the pot is offering you: what percentage of the time you need to win for calling a bet to be profitable. You compare it directly against your equity.
See example and numbersRange
The set of every hand someone can have in a given spot. In poker you never play against two cards: you play against a range.
See example and numbersSemi-bluff
Betting with a hand that is not the best today but has outs to become it. It wins two ways: when your opponent folds and when you complete your draw.
