Texas holdem hand range is one of the most important concepts in poker strategy.（德州撲克手牌範圍，是每一位玩家從新手進階的關鍵觀念）
這一篇會讓你：從【猜對手兩張牌】進階到【用Range（手牌範圍）思考對手】
InTexas Hold'em中，多數新手會嘗試：他到底拿的是什麼兩張牌？
但真正實用的做法是：
→ 你不需要猜到兩張牌
→ 你要判斷的是：他可能有哪些牌
這，就是 Range（手牌範圍）。
什麼是Texas Holdem Hand Range（手牌範圍）？
Range 不是神秘術語，你可以把它理解成：
→ 對手在這個位置、用這種方式進池與下注時，合理會出現的所有牌型集合
核心觀念：
→ 你不是在對抗一手牌
→ 你是在對抗一整個【可能性範圍】
新手最快建立Range的方法
你不需要背表，只需要看三件事
- 看位置（Position）：
– 前位（UTG）→ 範圍偏強
– 後位（BTN / CO）→ 範圍偏寬
結論：位置越後，Range越寬 - 看翻牌前行動（Preflop Action）
– Call → 偏中等牌
– Raise → 偏強或有主動權
– 3-Bet → 偏強或進攻型範圍
這一步，已經可以篩掉一半可能性 - 看翻牌後下注（Postflop Action）
問自己：
– 他是在拿價值？（希望你付錢）
– 還是在施壓？（希望你棄牌）
這會幫你判斷：是【強牌 / 聽牌】還是【空氣 / Bluff】
最簡單分類法
你可以先把對手 Range 分成三類：
→ 偏強（Strong Range）
→ 偏中（Medium Range）
→ 偏寬（Wide Range）
你只要先判斷這一層，決策就會穩很多
翻牌後怎麼縮小Range？
關鍵：【合理性過濾】
Step 1：看牌面（Board）
這個牌面：
→ 容易擊中誰？
→ 有沒有順子 / 同花 / 高張？
Step 2：對照行動
問自己：他的行動，符合這個牌面嗎？
情境1（合理）
→ 高張牌面
→ 對手翻牌前加注
→ 現在持續下注
因此：很合理（可能有擊中）
情境2（不合理）
→ 濕牌面（很多聽牌）
→ 對手一直大下注
→ 但他原本範圍不容易擊中
因此：可能是 Bluff（或極強）
結論：Range =【牌面 + 行動】的交集
Common mistakes made by beginners
硬猜兩張牌
→ 正確：先判斷範圍類型
把下注當答案
→ 正確：下注只是資訊的一部分
認為跟注＝弱
→ 很多玩家用中等牌或聽牌防守
想做到完美讀牌
→ 職業玩家也只是【縮小範圍】
進階觀念
Range會隨街道變化
→ Preflop：最大範圍
→ Flop：開始縮小
→ Turn / River：更集中
Range不是固定的
同一個玩家：
→ 在不同位置
→ 面對不同對手
→ 會有不同範圍
Quick Summary
→ Range＝對手可能的牌集合
→ 你不是在猜牌，而是在縮小範圍
→ 看位置 + 行動 + 牌面
→ 新手目標：少犯大錯，比猜對更重要
