Drawing to a straight with one of the middle cards missing, e.g. if you have 9-7 in the hole in Hold 'em, and the flop shows 6-10-A, an 8 would give you a straight. This is called a gutshot straight draw (also inside straight draw). "Because there were so many people in the hand, I easily got the odds to continue with my gutshot."
