Poker - Know Your Outs Part2

Example One
If you hold two suited cards and the flop brings two other cards of the same suit, you have a four-card flush. There are 13 cards in each suit. You have four of them, meaning that there are nine left in the deck. This means that you have nine "outs" to make your flush. With two cards to come, you have a 34.97 percent chance of making a flush. The odds are 1.86 against you making it. After the turn, with only one card to come the odds are 4-to-l against you.

Example Two
You have an unsuited Queen and Ten and the flop is A-9-8 rainbow (all different suits); you have an inside straight draw. The turn card is a "blank" which means it is no help to your hand. If you perceive that your opponent has a pair of Aces, you will need to make a straight to beat your opponent. There are four unseen Jacks that will give you a straight. You have four outs to make your hand. With one card to come you have an 8.7 percent chance of making it and the odds are 10.5-to-l against you.

Example Three
You have the King and Jack of hearts. The flop is Queen of clubs, Ten of hearts and 2 of hearts. You have nothing at this point but you have an open-ended straight draw. You can get one of the four Aces or one of the four 9s left in the deck for a total of eight outs. You also have a four-card flush giving you an additional seven outs for a total of 15 outs. There are nine hearts left in the deck but you have already counted the Ace and nine of hearts for your straight draw. With 15 outs you have a 54.1 percent chance of making a straight or a flush. The odds against you are only 0.81-to-l, which means you have a pretty good chance of drawing a winning hand.

The math used to determine the percentages and odds of making a hand is not difficult if you have a strong math background, but I found the calculations a little difficult to do without the benefit of a calculator. Let's take a look at the flush draw. You have four cards to the flush after the flop. You know there are 13 cards of each suit. You have four of them, which means there are nine remaining in the deck. You have two cards in your hand and there are three cards that were flopped so there are 47 cards remaining in the deck.
First we determine the odds for not making this hand. You have two chances to make the flush with the turn card or river card. For the turn you subtract the nine flush cards from 47 and you get 38 / 47. For the river you subtract nine from the 46 remaining cards to give you 37/46. Multiply 38/47 * 37 /46 = 1406/2162 = .65 or 65 percent of not making a flush. Subtract 65 from 100 and you see there is a 35 percent chance of making a flush.
I know that I am not capable of figuring odds like when I'm sitting at the table. So one of the alternatives would be to memorize a chart for all the outs. The Out Chart shows you percentages and odds for each number of outs after the flop with two cards to come and after the turn with one card to come.
