Plain-English definitions of the terms used across the Pokerai API and these ranges.Pokerai API 与这些范围里用到的术语,用大白话解释。
GTOgame-theory-optimal
A strategy that can't be exploited no matter how opponents adjust. It doesn't give one "best" move; each spot has a balanced mix of actions at specific frequencies. Pokerai returns those frequencies.无论对手怎么调整都无法被剥削的策略。它不给单一「最优手」,而是每个局面给一组按特定频率混合的动作。Pokerai 返回的就是这些频率。
Solver求解器 / Solver
Software that computes the GTO strategy for a spot by iterating (counterfactual regret minimization, CFR) until both players' strategies converge to equilibrium. Solving is compute-heavy — Pokerai serves millions of presolved spots instantly and solves the rest on demand.通过迭代(反事实遗憾最小化 CFR)计算某局面 GTO 策略、直到双方策略收敛到均衡的软件。求解很耗算力——Pokerai 把数百万预解局面即时返回,其余按需求解。
Mixed frequency混合频率
When GTO plays a hand more than one way — e.g. 99 might raise 64%, call 11%, fold 25%. You randomize per those frequencies so you stay unexploitable. A pure hand does one action 100% of the time.GTO 对某手牌不止一种打法——比如 99 可能 raise 64%、call 11%、fold 25%。你按这些频率随机化,保持不可剥削。纯手牌则 100% 只做一个动作。
RFIraise first in
Opening the pot with a raise when everyone before you has folded — an "opening range". Later positions open wider; UTG opens tightest.前面都弃牌后、你第一个用加注开池——即「开局范围」。越靠后的位置开得越宽,UTG 开得最紧。
3-bet / 4-bet
The 3rd and 4th raises in a betting sequence. The blinds count as bet 1, the open-raise is bet 2, so re-raising the opener is a "3-bet", and re-raising that is a "4-bet".一轮下注里的第 3、第 4 次加注。盲注算第 1 次下注,开局加注是第 2 次,所以再加注开局者叫「3-bet」,再加注它叫「4-bet」。
Isomorphic board同构牌面
Boards identical up to suit relabeling — A♠K♠2♠ and A♥K♥2♥ play the same. Collapsing these suit-symmetric duplicates to one canonical board is why ~66K flop spots cover every real flop.花色重命名后等价的牌面——A♠K♠2♠ 和 A♥K♥2♥ 打法完全一样。把这些花色对称的重复折叠成一个规范牌面,就是为什么约 66K 个 flop 局面能覆盖所有真实 flop。
EVexpected value
The average chips a decision wins or loses over the long run, in big blinds. GTO maximizes your EV assuming a worst-case opponent; the /v1/gto/evs endpoint returns per-action EVs.一个决策长期平均赢/输多少筹码(以大盲计)。GTO 在最坏对手假设下最大化你的 EV;/v1/gto/evs 端点返回逐动作 EV。
Blocker阻断牌 / Blocker
A card in your hand that removes combos from your opponent's range — e.g. holding the A♠ makes it less likely they have the nut flush. Blockers shape which hands bluff or call.你手里的一张牌减少了对手范围里的某些组合——比如你拿 A♠,对手有坚果同花的可能性就更低。阻断牌影响哪些手该诈唬或跟注。
SPRstack-to-pot ratio
Effective stack divided by the pot at the start of a street. Low SPR (short stacks, big pots) favors committing; high SPR leaves more room to maneuver. It's why 40bb and 100bb ranges differ.一条街开始时有效筹码 ÷ 底池。低 SPR(短码、大底池)倾向于投入;高 SPR 留更多操作空间。这也是 40bb 与 100bb 范围不同的原因。
Range范围 / Range
The full set of hands a player can have in a spot, each with its action frequencies. Pokerai's range pages and /v1/gto/preflop/range return all 169 starting hands at once.某局面下一名玩家可能持有的全部手牌集合,每手带各自的动作频率。Pokerai 的范围页和 /v1/gto/preflop/range 一次返回全部 169 个起手。
