Poker Terms
Throughout the course, I may say some poker terms you're unfamiliar with, so I've created the following list of poker terms for you to easily reference as you progress throughout the course.

3-Bet: The act of re-raising the initial raiser during pre-flop action.

All-In: The act of putting all of your remaining chips in the pot during a round of betting.

Backdoor Draw: When you need two additional cards to complete your straight or flush draw.

Balanced Strategy: Playing a wide range of hands the same way in certain situations to stay unpredictable versus good, thinking players.

Baluga Theorem: We should re-evaluate the relative strength of our hand when we face a raise on the turn.

Barrel: Another word for bet. A single barrel is a single bet. A double barrel is two bets in a row by the same person. A triple barrel is three bets in a row by the same person.

Big Blind: The larger of the two blinds in the game.

Blank Card: A card that does not improve your or your opponents’ hand.

Blind: A forced or partial bet put in by one or more players before any cards are dealt. There’s typically a small blind and big blind in No-Limit Hold’em.

Blocker: A card that reduces the number of combinations of hands in a player’s range.

Blocker Bet: A very small bet made to deter larger bets, with the goal of seeing the next card or getting to showdown as cheaply as possible.

Bluff: Betting or raising with an inferior hand, that has very little chance of improving, with the sole purpose of making our opponents fold a better hand.

Bluff Catcher: A hand that only beats bluff.

Board Texture: Refers to the suitedness and connectedness of the cards on the board and how it connects hole cards.

Button: A small, white, acrylic disk that indicates the dealer position in the hand. The dealer button moves clockwise each hand.

Capped Range: A pre-flop range of starting hands that has a ceiling to it, which typically doesn't include exceptionally strong starting hands.

Cold Call: Calling a raise after there has been a bet and one or more raises. Pre-flop, a cold call can occur in single-raised pots (because the blinds are considered the first bet) or in 3-bet or 4-bet pots.

Combined Fold Probability: The greater the number of players in a hand, the lower the probability they will all fold to a bet.

Combo Draw: A drawing hand that consists of more than one draw.

Continuation Bet (C-Bet): When a player who bet or raised in the prior round of betting bets again during the current round of betting.

Dead Money: Money sitting in the middle of the pot that players aren't aggressively fighting for.

Deep: Playing with a deep stack, usually when effective stack sizes are 150bb or more.

Depolarized 3-Bet: A 3-betting range composed solely of value bets. Sometimes called a strong linear range.

Diminishing Equity Concept: As more people enter a hand pre-flop, our probability of winning declines as each player acquires an equitable fair share portion of the pot.

Dominated Hand: A hand that’s dominated by a better hand due to its kicker card. For instance, KT is dominated by KQ.

Donk Bet: When a pre-flop caller bets out of position post-flop before it's the pre-flop aggressor's turn to act.

Effective Stack Size: The size of the smallest stack between two or more players in a hand. This indicates the highest amount of money you can either win or lose in a hand against any one particular opponent.
