Expected Value (EV)
The mathematical average outcome of a decision over infinite repetitions. Professional tournament players prioritize positive expected value decisions regardless of single-session results. Understanding EV separates successful competitors from casual players, as it focuses on long-term profitability rather than immediate outcomes.
Bankroll Requirements
The amount of capital needed to participate in tournaments at specific buy-in levels while withstanding normal variance. Financial experts recommend maintaining 20-40 buy-ins for the tournament level you're playing. This safety margin prevents catastrophic losses during inevitable downswings and ensures you can continue playing during adverse runs.
Bankroll Discipline
The commitment to only playing tournaments within your bankroll allocation. Bankroll discipline prevents overbetting and protects players from financial ruin. Many successful competitors move down in stakes during losing periods and move up only after significant wins—this approach preserves capital and maintains emotional stability.
Tournament Structure
The specific rules governing a tournament, including blind levels, antes, time limits, and payout structures. Different structures favor different strategic approaches. Aggressive deep-stacked structures reward skilled aggressive players, while short-stacked structures increase variance and reduce decision-making complexity.
Fold Equity
The value gained when opponents fold their hands rather than call your bet. Understanding fold equity helps tournament players select betting amounts and situations where opponent surrender has high probability, improving overall profitability through pressure plays.
