Texas Hold'em Terminology Dictionary
Gutshot Straight Draw（卡順），又稱 Inside Straight Draw（內嵌順聽），是指玩家只缺中間的一張牌即可完成順子，因此通常只有 4 Outs。例如持有 8♠9♦，牌面為 6♣10♥K♠，只有補到 7 才能完成順子
雖然 Gutshot 的完成機率低於 Open-Ended Straight Draw（兩頭順聽牌），但在擁有良好的 Pot Odds、Implied Odds 或 Fold Equity 時，仍可能成為高EV的選擇
本篇將完整介紹 Gutshot 的定義、4 Outs、勝率、Pot Odds、Semi Bluff、GTO 應用，以及職業玩家如何利用 Gutshot 提升長期EV
An Open-Ended Straight Draw (OESD) means the player currently has four consecutive cards, and both ends of the straight can complete the draw, thus typically having 8 outs. For example, holding 8♠9♦, with a board of 6♣7♥K♠, drawing a 5 or 10 would complete the straight.
With its numerous outs, OESD is one of the strongest straight draws in Texas Hold'em, and it is often paired with Pot Odds, Implied Odds, Fold Equity, and Semi Bluff to create high EV.
This article will provide a complete introduction to the definition of OESD, 8 Outs, win rate, Pot Odds, Semi Bluff, GTO applications, and how professional players use OESD to improve long-term EV.
A straight draw is a hand where a player is just one card away from completing a straight. Depending on the missing card, it can be categorized as an open-ended straight draw, a **gutshot straight draw**, and other special types. A straight draw is one of the most important drawing hands post-flop and is a crucial foundation for calculating pot odds, outs, semi-blushes, and equity.
