Texas hold ' em, it is essential to be able to calculate your outs and your odds. First, a brief description:
Calculate odds and outs
Your "outs" are the number of remaining cards in the deck that could improve your hand. For example, let's say that you have AK in hearts and the flop comes out with two hearts and no pair. You need a heart to make your flush. There are 13 hearts in total in the deck. You've seen 4 of them (two in your hand, and two on the board), then there are 9 hearts remaining in the deck. There are 52 cards in the deck, you've seen five (your hand and the flop), then it leaves 47 cards. Of these 47 cards, 38 are not hearts and 9 are. So your odds to hit a heart to the next map are of 38:9, or approximately 4: 1. To determine your odds of making your hand through the River, cut the odds of half (since you have two chances). So your odds to make a flush on the River are of approximately 2: 1 (two to one).
The pot odds
The pot odds are the ratio between you need caller and the size of the pot. Then if the pot is $ 100 and you need caller bet $ 50 to see the next card, your odds are of 100:50 or 2: 1 (two to one).
Phil Gordon suggests an easy way to calculate the odds in the following video:
As a general rule, if your pot odds are better than the odds of making your hand, you should caller. Otherwise, you should folder. You must develop skills to calculate your outs and your odds, because your will need this information for each hand.
To simplify the process, I use a tool called Tournament Indicator (indicator of tournament), which calculates this information for me at the right time. In this way, I can bring my attention to the situation of the table instead of doing the math in my head. In the example below you are developing to make a straight draw - a 6 will give you a straight. Tournament Indicator shows you the odds of making a straight and your pot odds. Usually, if your pot odds are better than the odds of making a straight, you should caller. Otherwise, you should folder. I will speak of exceptions in the advanced lessons that will follow.
