Count your OutsFor some reason there often seems to be confusion about odds in poker. I think partly this is due to the fact that there are a variety of different aspects to odds as well as different methods of for calculating or viewing them. As a bit of a project I thought that I'd try to organize and summarize the various aspects that I've come across. But before looking at odds, we have to be able to count your chances.Outs, what are they and how do you count them? Outs are chances or different possibilities that your hand might improve. You holdA What are your chances of getting a flush? To get a flush you need one more spade. There are 13 spades in a deck, 4 are known (you have two and two are in the flop) so there are 13 - 4 = 9 remaining spades. Each chance is called an "out", so you have 9 outs to make the flush. It doesn't matter whether someone else had or has a spade in their hand. Unless someone tells you that they folded a spade or you're watching televised poker you won't know if another spade has been seen, so for calculating your outs it doesn't matter. (Obviously if you're playing Stud or some other game where you can see other cards that are gone then those cards have to be deducted from your total outs) What if you suspect your that opponent has paired the king? In that case if an Ace comes you will be beating him with your higher pair. There are 4 Aces in the deck, and you have one so 4 - 1 = 3 aces as outs. If, as you suspect, your opponent has paired the King, then if you get an Ace or if you get a spade, you will be beating him so you can add the outs, 9 spades + 3 Aces = 12 outs.~ |

Let's look at straights. You hold 9 Now if a 10 or 5 of any suit comes, you will have a straight. There are four 10s and four 5s so 4 + 4 = 8 outs to get a straight. Say you hold 9 Now only a 7 fills your straight (these are called "inside" or "gut shot" straight draws). Four 7s = 4 outs to fill the gut shot straight. Or, you hold 9 Now, a 7 fills your 56789 straight, but a T fills your 789TJ straight. This is the "double gutshot" or "double belly buster" straight draw with four 7s and four Ts to fill a straight so 4 + 4 = 8 outs. ~ Try one more.This time you have 9 ![]() ![]() ![]() ![]() ![]() You think you will win if you hit a flush or a straight. To get there, you have nine outs for the flush draw (K ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() Clean outs, Tainted outs Sometimes not all of your outs are always going to win for you if they hit.Say you have 9 ![]() ![]() ![]() ![]() ![]() This time, your opponent knocks over his cards in his excitement and you see that he holds two more Aces for a set of Aces.

He's also ahead of you at the moment, though neither of you know that at the time. If you did know each other's cards (if one of you is all in and the cards have been turned over) you would see that a 5 ![]() ![]() ![]() ![]() ![]() ![]() Partial Outs In the last examples the tainted outs were counted as 1/2 outs because their value may be questionable. There are other situations where you will encounter partial outs. This will happen often on the flop because you have the turn and river cards yet to come. For example, you have 9 This time if both the turn and river cards are spades you can still hit a runner-runner flush. How often does a runner-runner flush come in? There are ten remaining spades. On the turn there are 52 total cards - 5 known cards = 47 cards remaining. Assuming that you caught a spade on the turn, at the river there are 9 more spades remaining and 52 total - 6 known cards = 46 remaining cards. Therefore, the chances of the turn being a spade are 10 in 47, and if it is, the chance of the river also being a spade is 9 in 46. The math calculation is (10/47)(9/46) = 4.16% or slightly better than a 1 in 25 chance (actually closer to 1 in 24). Not particularly good odds; runner-runner flushes are usually valued as one or perhaps 1.5 outs. The
7 ~ Okay, that took longer than I expected just to cover outs. If you have questions, or you think that I've missed something, feel free to send an email or leave a comment. |
