SB/BB/Ante → 每圈消耗与还能撑几圈
M值（M-Ratio）是德州扑克锦标赛中衡量玩家筹码健康度的核心指标，由丹·哈灵顿提出，定义为玩家筹码量除以当前盲注与底注的总和（即每轮游戏的总成本）。实战中，M值直接反映玩家的生存压力与策略紧迫性：M值高于20时处于舒适区，可灵活操作；M值低于10则进入危险区，需积极寻找全下机会；M值低于5时几乎只能被迫全下。例如，在盲注500/1000、底注100的9人桌，每轮成本为500+1000+100×9=2400，若玩家筹码为24000，则M值为10，意味着他仅能承受10轮盲注消耗，必须立即采取激进行动，否则将因盲注吞噬而淘汰。
Thuật ngữ底注（Ante）是德州扑克中所有玩家在每手牌开始前必须投入底池的强制下注，通常金额较小且固定。它的核心作用是增加底池初始规模，迫使玩家更积极地参与手牌，从而加快游戏节奏并减少过于保守的弃牌策略。在实战中，底注常见于锦标赛后期或现金游戏的特定阶段，能有效提升底池赔率，鼓励玩家用更宽的范围入池。例如，在九人桌的锦标赛中，每位玩家需在发牌前支付100筹码的底注，底池初始就有900筹码，使得即使持有弱牌，玩家也可能因潜在回报而选择跟注或加注，而非轻易弃牌。
Orbit cost ≈ antes + small blind + big blind (in BB). In MTTs, passive blind loss compresses the M value, forcing wider steals or earlier push-fold. In high-ante structures, the orbit cost's share of the stack increases, and when ICM is layered in, the opportunity cost of "not playing" becomes more significant. Use the calculator on this page to instantly compute the breakeven win rate, then cross-reference the numbers with opponent ranges, position, and turn/river plans – avoid just memorizing formulas without being able to apply them at the table.
Ignoring antes in deep stacks leads to inflated M values; only counting blinds and not antes. Not updating the orbit cost before the money bubble. Misapplying orbit-cost in cash games. Also, don't treat Solver frequencies as an inviolable rule that eliminates the need to verify pot odds; when information is incomplete, ICM and SPR remain the first principles of tournament poker.
At the start, note "X bb per orbit"; synchronize with m-ratio and break-even-steal. Recalculate steal frequency when antes double. In reviews, ask "How many BB did I lose just from the blinds?" – that drives the rationality of widening. Each week, pick five real hand histories, recalculate them with the same tool, and revisit the glossary to review concepts like pot odds, ICM, SPR, etc., which will auto-link. Cross-referencing with push-fold and MDF helps build a complete preflop and postflop math framework faster.
Scenario：Chips 25,000, 8-handed table ante 25.
Cost per hand = 100 + 200 + 25 × 8 = 500 2. Per orbit ≈ 500×8 = 4,000 3. Blinds break after about 6.25 orbits
Conclusion：Already in orange/red zone, need to actively steal blinds or push.
Scenario：Context: Tool example scenario: orbit-cost
Chips 80,000, blinds 500/1000/100, 9 players.
Conclusion：In the early stages, you can still play according to strategy, without having to push/fold immediately.
Scenario：Context: Tool example scenario: orbit-cost. Table A has high ante, Table B has low ante.
Choose tables with low cost to extend survival. 3. Tool example step: orbit-cost
Or choose a higher-cost table to grab a bigger pot.
Conclusion：Changing tables is one of the MTT techniques; cost affects steal frequency.
