紧弱玩家（Nit）指只玩极强起手牌、入池后倾向于被动弃牌的保守型玩家。实战中，这类玩家通过严格筛选手牌规避风险，但容易被激进玩家利用，频繁弃牌导致损失底池。典型场景：翻牌前，Nit只用AA、KK或AK加注入池；翻牌后，面对持续下注，若未击中超强牌（如暗三条），即便持有顶对也会弃牌，长期来看盈利效率较低。
術語期望值（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。
術語[MP](/term/mp)（[Middle Position](/term/middle-position)，[中间位置](/term/middle-position)）是德州扑克中位于[枪口位](/term/utg)（[UTG](/term/utg)）之后、[关煞位](/term/cutoff)（CO）之前的座位区域，通常包括[UTG+1](/term/utg-1)和UTG+2（在9人桌中）。核心用途是界定玩家在翻牌前的行动顺序和相对[位置优势](/term/position-advantage)：MP比前位有更多信息，因为能观察前位玩家的行动，但比后位（CO、BTN）缺乏位置控制力。实战中，MP的起手牌范围应比前位稍宽，可加入中等对子、同花连牌等，但仍需谨慎，避免被后位玩家挤压或慢打。MP玩家需平衡激进与保守，利用[位置优势](/term/position-advantage)在翻牌后根据对手范围做出决策，同时防范后位玩家的偷盲或加注。
術語高额桌指盲注或买入金额远高于常规水平的扑克牌局，通常涉及职业玩家和巨额资金。实战中，高额桌考验的是顶尖心理博弈和资金管理能力，因为单局输赢可能超过普通人年收入，玩家必须精准读牌并控制情绪。例如，在盲注1000/2000美元的无限注德州扑克局中，一次全押可能涉及数十万美元，只有经验丰富且资金充裕的玩家才能承受这种波动。
術語波动（Variance）指德州扑克中因短期运气因素导致的实际结果与数学期望值之间的偏差程度。在实战中，波动决定了玩家在特定时段内可能经历的盈利或亏损幅度，即使长期决策正确，短期也可能因发牌或对手的随机性而遭遇连败或连胜。理解波动有助于玩家保持情绪稳定，避免因短期结果质疑自身策略。例如，你拿着AA全下，对手用72不同花跟注，河牌发出两张7让你输掉底池，这就是典型的高波动场景——你的胜率高达88%，但短期结果仍可能偏离预期。
術語专注指玩家在牌局中排除干扰、全神贯注于对手行动、牌面变化及自身策略的心理状态。实战中，专注能帮助捕捉对手的马脚、计算赔率并避免冲动决策，是长期盈利的基础。例如，在翻牌圈持续下注时，专注的玩家会留意对手是否因紧张而手抖，从而判断其牌力强弱，而非因分心错过关键信息。
