Gutshot
An inside straight draw that can be completed by only one rank.
In depth
A gutshot, or inside straight draw, is a hand that can complete a straight with only one specific rank. Unlike an open-ended draw, which has two possible completing cards, a gutshot has a single way to improve, making it a narrower and weaker drawing opportunity. This distinction helps players accurately assess their hand’s potential.
