Poker Rules, Odds and Terminology

PokerAddict is a reference desk for people who want to understand poker rather than follow it. Every page here answers a question that comes up at the table: how a variant is dealt, which hand wins, how often a draw arrives, what a term on the screen means.

Nothing on the site reports results or chases headlines. The pages are written to be read once and returned to later, so the rules, probabilities and vocabulary stay in one place and stay consistent with each other.

Rules, order of play and hand-making requirements for the poker variants dealt in card rooms and online.

Texas Hold'em

Two hole cards, five shared community cards and four betting rounds: the full order of play, the blinds, the showdown rules and the vocabulary that goes with them.

Pot-Limit Omaha

Four hole cards, five community cards and one rule that changes everything: exactly two hole cards must be used. Rules, pot-limit betting and the hands that actually win.

Omaha Hi-Lo

Omaha with the pot split between the best high hand and the best qualifying low. How the eight-or-better qualifier works, how to read a low, and why scooping decides the game.

Seven-Card Stud

The game played before hold'em took over: no community cards, five betting rounds, and information that comes from the cards your opponents show.

Razz

Seven-card stud played for low: the worst hand wins, straights and flushes are ignored, and the best possible holding is five-four-three-two-ace.

Short-Deck Hold'em

Hold'em with the deuces through fives removed: 36 cards, a reordered hand ranking, ante-driven betting and far more big hands than the full deck produces.

The decisions that decide most hands: position, starting hands, pot odds, bet sizing and bankroll discipline.

Starting Hands

Which two cards are worth playing, why suitedness is worth less than it looks, and how domination explains most of the money lost before the flop.

Table Position

Why acting last is the single largest structural advantage in poker, what each seat is called, and how opening ranges change from the blinds to the button.

Pot Odds and Equity

How to turn a drawing hand into an arithmetic question: counting outs, converting them to a percentage, and comparing that figure with the price the pot is offering.

Bet Sizing

Why bets are measured against the pot rather than the hand, what each size offers an opponent, and how sizing changes between value bets, bluffs and draws.

Bluffing

What a bluff actually needs to work: a believable story, a hand that cannot win at showdown, and a price that makes folding reasonable for the opponent.

Continuation Betting

The bet that follows a pre-flop raise: when the flop justifies it, which sizes to use, and why betting every flop stopped working years ago.

Hand rankings, probabilities, table positions, betting structures and tournament formats in one place.

Hand Rankings

The ten poker hands in order, how often each one appears in a five-card deal, and the rules that settle ties between hands of the same rank.

Poker Probabilities

The numbers behind the common decisions: how often hands are dealt, how often draws complete, and what each flop texture appears at.

Table Positions

Every seat at a poker table named and explained: the blinds, under the gun, the lojack, hijack, cutoff and button, at nine-handed, six-handed and heads-up tables.

Betting Structures

No-limit, pot-limit, fixed-limit, spread-limit and cap games compared: what each allows, how raises are calculated, and how the structure changes the way a variant plays.

Tournament Formats

Freezeouts, re-entries, bounties, satellites, shootouts and turbos: what each format changes about entry, elimination and the way a stack should be played.

Poker Timeline

How poker reached its present form: the betting games that preceded it, the spread of the 52-card deck, the arrival of community cards, and the online era.

How the best-known live tournament circuits are organised, and what the formats mean for the people who enter them.

World Series of Poker

How the WSOP is structured: a summer schedule of open events across many variants, bracelets as the prize for winning one, and a no-limit hold'em main event.

World Poker Tour

A touring series of televised no-limit hold'em championships: how stops, main events and final tables are organised, and why broadcast shaped its format.

European Poker Tour

A festival-style circuit of stops across Europe: a main event, a schedule of side events, high rollers, and online satellites that fill much of the field.

High Roller Series

How super high roller events differ from open tournaments: small fields, very large buy-ins, re-entry, short-deck variants and structures built for experienced players.

Poker Hall of Fame

What the Poker Hall of Fame recognises, the criteria used for induction, and why the standard covers contribution to the game as well as results at the table.

How This Site Is Organised

Four sections carry the whole site, and each answers a different kind of question. If you are new to the game, the order below is the order worth reading.

How to Play

Rules for each variant: what is dealt, how the betting proceeds, and which five cards make the hand.

Strategy

The recurring decisions — position, starting hands, pot odds, bet sizing — explained with the arithmetic behind them.

Reference

Rankings, probabilities, seat names, betting structures and tournament formats, kept as lookup pages.

Tournaments

How the major live circuits are structured and what their formats ask of the people who enter them.

Numbers quoted across the site come from a single source file, so a probability stated on one page matches the same probability stated on another. Where a figure is an approximation, the page says so.
