下注尺度 → 对手需弃牌比例，诈唬才有正 EV
Fold Equity refers to the probability of winning the pot by making opponents fold through bluffing. Break-even fold equity = bet size ÷ (pot + bet size). If the opponent's actual fold equity is higher than this value, a pure bluff is +EV.
Fold equity ≈ Opponent's fold frequency × (current pot + dead money). Semi-bluff EV = fold equity + equity when called × subsequent pot. Short-stack steals and drawing raises rely on fold equity; directly related to break-even-steal. When ICM pressure is high, opponents over-fold, increasing fold equity but Chip EV may not necessarily be higher. Use the calculator on this page to instantly compute break-even win rate, then cross-check the numbers against opponent range, position, and turn/river plans to avoid just memorizing formulas without applying them at the table.
Frequent blind stealing in tight games; over-bluffing when blocking nutted hands. Failing to account for implied/reverse implied odds after being called. Treating tournament bubble situations as cash game fold rates. Also, do not treat Solver frequencies as golden rules that need no pot odds verification; with incomplete information, ICM and SPR remain the first principles in tournaments.
Estimate fold to steal / fold to cbet before acting. Calculate semi-bluff EV together with pot odds. When reviewing bluffs, check if opponent's range had too many continues and calibrate frequencies. Each week, pick five real hand histories and recalculate using the same tool, then revisit the glossary to review concepts that auto-link such as pot odds, ICM, and SPR. Cross-referencing with push-fold and MDF can help you build a complete preflop and postflop math framework faster; short-stack steals must be checked against break-even-steal.
Scenario：Context: Tool example scenario: fold-equity
The pot is 80, you bet 40 as a pure bluff.
Required fold equity = 40 ÷ (80 + 40) = 33.3% 2. If opponent folds in this spot about 45% 3. Context: Tool example step: fold-equity
Conclusion：Bluffing is profitable at this size (not counting equity when called).
Scenario：Pot 80, opponent bets 40, you have 8 outs.
8 outs on turn about 16%, combined on river about 32% 3. Context: Tool example step: fold-equity
Pure pot odds are insufficient; need to evaluate implied odds and position.
Conclusion：Without implied odds, calling on the turn is too loose; with reliable implied odds or opponent overpay, you can continue.
Scenario：Context: Tool example scenario: fold-equity
Pot is 200, you consider betting 50 for thin value.
Conclusion：Thin value betting is essentially a scaled-down pot odds problem; the smaller the bet size, the wider the required calling range.
期望值（Expected Value）是衡量一个决策在长期重复中平均盈利或亏损的数学指标，正EV表示盈利，负EV表示亏损。
ศัพท์下注尺度指玩家在扑克下注轮中选择的下注金额大小，通常以底池百分比或具体筹码数表示。实战中，合理控制下注尺度能有效管理对手赔率、塑造自身范围并最大化价值或诈唬效率。例如，在翻牌圈手持顶对顶踢脚时，若底池为100筹码，下注33筹码（约1/3底池）可迫使听牌跟注不划算，同时引诱弱对子跟注；而在河牌圈坚果牌时，下注80筹码（约4/5底池）则能榨取对手最大支付。典型场景：面对紧凶对手，小尺度下注（如1/4底池）可引诱其加注诈唬，而大尺度（如满池）则适合对抗跟注站型玩家。
ศัพท์[Bet](/term/bet)（[下注](/term/bet)）指玩家在未有任何下注行动的轮次中，主动投入筹码的行为。它是德州扑克中最基本的进攻性行动，核心用途在于建立底池、表达牌力强度或施加压力迫使对手弃牌。在翻牌前，下注通常由[大盲注](/term/big-blind)左侧玩家开始；在翻牌后，则由行动顺序中首个未弃牌的玩家发起。实战中，下注的金额大小可传递不同信息：[小额下注](/term/underbet)可能意在试探或价值提取，大额下注则常代表强牌或诈唬。合理运用下注能控制[底池赔率](/term/pot-odds)、保护手牌或制造弃牌率，是平衡攻防策略的关键工具。
ศัพท์诈唬（Bluff）是指在德州扑克中，通过下注或加注来代表持有强牌，实际手牌较弱，目的是迫使对手弃牌从而赢得底池。这一术语的核心在于利用对手的恐惧心理，制造虚假的牌力信号，以低成本夺取本不属于自己的筹码。实战中，诈唬是平衡攻击性和控制底池的关键工具，能迫使对手在不确定中犯错，尤其适合在对手范围较弱或牌面干燥时使用。典型场景：翻牌圈你持有完全无听牌的底牌，但公共牌面出现高牌，你持续下注，对手因担心你击中顶对而弃牌，你成功诈唬赢下底池。
ศัพท์底池权益是指玩家在当前手牌中，根据底池赔率和对手范围，预计能赢得的底池份额百分比。在实战中，底池权益帮助玩家判断是否值得继续下注或加注，是决策的核心依据之一。例如，翻牌圈你持有同花听牌，对手下注半个底池，你的底池权益约为36%，而底池赔率要求33%的胜率即可跟注，此时跟注是正期望值的选择。通过计算底池权益与底池赔率的对比，玩家可以避免长期亏损，优化资金管理。
ศัพท์弃牌权益是指玩家通过下注或加注迫使对手弃牌而赢得的底池份额，是激进打法中期望值的核心组成部分。实战中，它帮助玩家在牌力不强时仍能获利，尤其当对手弃牌概率较高时，可显著提升整体盈利。例如，在翻牌圈持有听牌时，若底池有100筹码，你下注80筹码，对手有40%概率弃牌，那么你的弃牌权益就是40筹码（100×40%），结合自身牌力赢率，总期望值可能为正，从而支持激进下注。
ศัพท์弃牌（[Fold](/term/fold)）是指玩家在行动轮中主动放弃当前手牌，不再参与该局游戏。核心含义是承认当前手牌胜率不足或潜在损失过大，从而避免投入更多筹码。在实战中，弃牌是控制风险的关键手段，尤其当对手示强、[底池赔率](/term/pot-odds)不利或自身牌力较弱时，果断弃牌能有效减少长期损失。优秀的玩家懂得在适当情况下弃牌，而非盲目跟注或加注，这是实现盈利的重要策略之一。
