Explanation of Open ended straight draw
An open ended straight draw is where the cards required to complete our straight appear on the outside of our structure. For example, we hold 6, 7, 8 and 9. In this instance, any Ten or Five will complete our straight. We are hence roughly twice as likely to complete an open ended straight draw as opposed to an inside straight draw or gutshot.
Here is a Hold’em example.
Board: K♣T♣5♠
Hand: J♦Q♦
Here we flop an open ended straight draw since any Ace or Nine completes the straight.
Example of Open Ended Straight Draw being used in a sentence -> Our open ended straight draw bricked on the river, so we had no choice but to fold against our opponent’s followup bet.
