Position refers to a player's seat relative to the dealer button. Early position (closer to the small blind) requires stronger hands, while late position (closer to the button) allows more flexibility. Position is one of the most important factors in poker strategy, as it determines the information you have when making decisions.

Pot odds are the ratio of the current pot size to the cost of your next bet. Understanding pot odds helps determine whether calling a bet is mathematically profitable. If the pot odds are favorable relative to your hand's winning probability, the call is a sound mathematical decision.

A range is the complete set of hands an opponent might have in a given situation. Advanced players think about ranges rather than specific hands. Analyzing opponent ranges allows you to make more accurate decisions and adjust your strategy based on their likely holdings and tendencies.

Equity represents your hand's winning probability against an opponent's range. Calculating equity helps you understand whether your hand is strong enough to continue in the hand. Hand equity changes as community cards are revealed, so players must constantly reassess their situation.

A check is a decision to pass without betting. Only available when no one has bet during the current round, checking allows you to remain in the hand without wagering additional chips. Checking provides valuable information about opponent strength.

Folding means surrendering your hand and forfeiting all chips wagered in the current hand. Folding is a crucial decision in poker strategy, especially when your hand has insufficient equity or when facing aggressive betting. Knowing when to fold protects your bankroll.

A raise increases the current bet amount, forcing other players to match the new bet or fold. Raises are used to build the pot with strong hands, eliminate weaker hands, or apply pressure through aggressive play. The size and timing of raises convey important strategic information.

Going all-in means wagering all remaining chips. All-in bets are critical decision points in tournaments and define significant strategic moments. Players must carefully evaluate hand strength, opponent tendencies, and chip stacks when considering all-in moves.

Expected value is the average outcome of a decision made repeatedly over time. Positive EV decisions profit mathematically, while negative EV decisions lose money. Professional players focus entirely on making the highest EV decision, regardless of short-term results.

Bankroll management involves maintaining an adequate money supply for your poker level and protecting it through proper stake selection. Professional players keep their session stakes small relative to their total bankroll, ensuring they survive variance without risking ruin.

Game Theory Optimal (GTO) strategy finds unexploitable plays, while exploitative play takes advantage of opponent mistakes. Winning players balance both approaches: using GTO fundamentals as a foundation while identifying and exploiting opponent tendencies.

Variance is the natural fluctuation in results despite playing perfectly. Even optimal players experience losing periods due to luck. Understanding variance helps players maintain emotional discipline and prevents overreacting to short-term downswings.

Premium hands like pocket aces, kings, queens, and ace-king should be played aggressively from most positions. These hands have the highest equity and should generate profit when played correctly.

Marginal hands have moderate strength and require careful position-dependent play. These hands warrant different decisions depending on position, stack sizes, opponent tendencies, and action flow.

Drawing hands need improvement to win, such as four-card flushes or straights. These hands are profitable when pot odds support the
