In depth
An open-ended straight draw is a hand that can complete a straight by obtaining a card at either end of a four-card sequence. This occurs when a player holds four consecutive cards, allowing two possible ranks to complete the straight, providing more outs than a gutshot draw. The structure appears on coordinated boards and affects hand equity in poker play.
