Basic Strategy
In Blackjack, the mathematically optimal play for every possible hand combination against each dealer's visible card. Following basic strategy reduces the house edge to approximately 0.5%. Professional players memorize basic strategy charts to make statistically sound decisions.
Expected Value (EV)
The average amount a player should expect to win or lose per bet over extended play. Positive EV bets win money on average; negative EV bets lose money. All casino game decisions should be evaluated through the lens of expected value.
Position
A player's location relative to the dealer in table games, affecting the order of play. Position determines when you act and what information you have about other players' decisions. In poker, position is a crucial strategic advantage, influencing hand selection and betting decisions.
Variance
The fluctuation in results around the expected value over the short term. High variance games show larger swings between wins and losses. Understanding variance is essential for proper bankroll management and realistic expectations about gaming sessions.
Volatility
Similar to variance, volatility describes how unpredictably a game's results may swing. Games with higher volatility require larger bankrolls to weather downswings without depleting funds completely.
Hand Range
All possible combinations of cards a player could hold in a given situation. Advanced players think in terms of ranges rather than specific hands, allowing for more sophisticated probability calculations and strategic decisions.
