Open Ended Straight Draw >>> Straight with
2 Cards to Come
The odds of completing an open-ended Straight draw with
2 draws to come are a lot better than with only one draw
left. In the above example, the odds of making the Straight
on the Turn are almost 5 : 1. As you can see below, the odds
of making the Straight on EITHER or both the Turn or
River are just over 2 : 1.
Of 47 unseen cards, 8 will make the straight and 39 will not:
8 * 39 = 312
312 2-card combinations will contain 1 and only 1 Straight
card.
(8 * 7) = 28
(1 * 2)
28 2-card combinations will contain 2 Straight cards including
the possibility of a Pair.
312 + 28 = 340 possible 2-card combinations that WILL
make the Straight:
Total Possibilities = 1,081
– WILLs = 340
WILLNOTs = 741
