百分比 ↔ 分数 ↔ X:1 比例，统一换算
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。
Glossary[底池赔率](/term/pot-odds)（[Pot Odds](/term/pot-odds)）指当前底池总额与玩家需要跟注的金额之比，通常以比例或百分比表示。核心用途是评估跟注的数学[期望值](/term/expected-value)：若手牌胜率高于底池赔率，则跟注长期有利可图；反之则应弃牌。实战中，玩家通过快速计算底池赔率，结合对手范围与[隐含赔率](/term/implied-odds)，判断是否值得追逐听牌或边缘牌。例如，底池100元，对手下注50元，底池赔率为150:50（3:1），若手牌胜率超过25%，跟注即正[期望值](/term/expected-value)。该概念是德州扑克决策的基础工具，帮助玩家避免情绪化下注，实现长期盈利。
Tools底池 + 跟注额 → 盈亏平衡胜率
Odds form conversion: fractional odds F:1 ↔ win probability p = F ÷ (F+1); isomorphic to pot odds (required win probability = call ÷ (pot+call)). Percentages, ratios, and odds are unified, making it easy to compare outs equity with the pot odds given by an opponent's bet. For on-the-fly mental calculation, it is recommended to memorize the win probabilities corresponding to 2:1, 3:1, 4:1. Use the calculator on this page to instantly compute break-even win probability, then cross-reference that number with the opponent's range, position, and turn/river plans — avoid simply memorizing formulas without being able to apply them at the table.
Treating “3:1 odds” as a 75% win probability (it's actually about 25% against). Confusing the numerator and denominator of pot odds vs. implied odds. Rounding in the wrong direction, leading to misjudgment in marginal spots. Also, do not treat Solver frequencies as infallible rules that override pot odds checks; when information is incomplete, ICM and SPR remain the first principles of tournament play.
After practicing the conversion table, cross‑validate with pot‑odds and outs tools. In reviews, first convert the opponent's bet into the required win probability before making decisions. Memorize the relationship between alpha and odds alongside alpha and MDF. Each week, pick five real hand histories, recalculate them using the same tool, and return to the glossary to review concepts such as pot odds, ICM, SPR, etc., which will be automatically linked.
Scenario：Estimate the win rate of a drawing hand at 35%.
Ratio approximately 65:35 ≈ 1.86:1 against 3. Context: Tool example step: odds-converter
Approximately need 2:1 pot odds to be enough.
Conclusion：35% equity corresponds to approximately 2:1 pot odds requirement.
Scenario：Pot is 80, opponent bets 40, you have 8 outs.
8 outs: about 16% on the turn, about 32% total by the river. 3. Pure pot odds are not enough; need to assess implied odds and position.
Conclusion：Without implied odds, calling on the turn is too loose; with reliable implied odds or if the opponent overpays, you can continue.
Scenario：Pot 200, you consider betting 50 for thin value.
Conclusion：薄价值下注本质是缩小版 pot odds 问题，尺度越小所需跟注范围越宽。
