rake 贡献 × 返水比例 → 估算返水收益
赢率是衡量玩家在长期扑克游戏中盈利能力的核心指标，通常以每百手牌赢取的大盲注数（bb/100）表示。实战中，赢率用于评估策略有效性、筛选对手或判断自身水平，高赢率意味着稳定的正期望值。例如，一位线上玩家在NL100级别打10万手牌后，赢率为5bb/100，意味着他平均每百手牌净赚5个大盲注，即5美元。典型场景中，若你发现对手赢率超过10bb/100，可能需调整对抗策略，因其盈利模式过于激进。赢率需结合手牌样本量（至少数万手）分析，短期波动较大，长期才具参考价值。
Glossary抽水（Rake）是扑克室从每手现金局底池或锦标赛报名费中抽取的固定比例或固定金额佣金，是平台运营的主要盈利方式。在实战中，抽水直接影响玩家的长期盈利，因为即使赢下底池，也需要扣除这部分成本，因此低抽水或抽水封顶的牌局对玩家更有利。典型场景：在现金局中，底池达到10美元时，扑克室按5%抽取0.5美元作为抽水，剩余9.5美元归赢家；锦标赛则通常从报名费中直接扣除，如100美元报名费含10美元抽水。
Glossary返水（Rakeback）是指扑克室根据玩家在牌局中贡献的抽水（Rake）总额，按约定比例返还给玩家的奖励机制。其核心用途是降低玩家的长期游戏成本，提升盈利空间，尤其对高频玩家或职业牌手意义重大，因为抽水是持续消耗资金的隐性支出。例如，在一手牌中你支付了1美元抽水，若扑克室提供30%返水，则你最终可获0.3美元返还。典型场景是玩家注册时选择返水计划，每月累积抽水后，平台自动结算返水至账户，相当于变相提高胜率或减少亏损。
Rakeback returns part of the rake, effectively reducing the cost per hand: adjusted EV ≈ book EV + rakeback. High-frequency small pots and marginal preflop strategies are sensitive to rake; closely related to bankroll and profitability of marginal preflop-equity hands. When selecting tables, rebates are part of the real hourly rate. Use the calculator on this page to quickly calculate the break-even win rate, then compare the numbers with opponent ranges, position, and turn/river plans, to avoid just memorizing formulas without applying them at the table.
Only looking at win rate without considering rake; overestimating rebate and playing too loose. Playing live without rakeback but still choosing tables based on online EV. Confusing MTT entry fees with cash game rake. Also, don't treat Solver frequencies as golden rules without checking pot odds; when information is incomplete, ICM and SPR remain the first principles in tournaments.
Calculate "rake cost per 100 hands" then evaluate tightness/looseness. Consider together with EV and variance: higher rebate can slightly lower BRM requirements. Record long-term net win curve including rebate. Each week, pick five real hand histories and recalculate using the same tool, and go back to the glossary to review concepts like pot odds, ICM, SPR, etc. (which auto-link). Comparing with push-fold and MDF can help build a complete preflop and postflop math framework faster.
Scenario：Monthly rake contribution $500, rakeback 27%.
Equivalent to reducing effective rake. 3. Context: Tool example step: rakeback
Must be included in the long-term winrate.
Conclusion：Monthly rakeback $135, yearly approximately $1,620 additional income.
Scenario：NL25 lost 5 buy-ins, want to move up to NL50 to recover.
Check if BRM still meets 20+ buy-in 3. Should first reduce bet or stop and review.
Conclusion：Raising stakes after consecutive losses violates BRM; lowering stakes or taking a break is a better choice.
