How Not to Suck at Poker: Learn Basic Poker Odds
Like it or not, Texas Hold'em is an odds game.
Like it or not, Texas Hold'em is an odds game.
Every action you make, hand you play or bet you face has odds, probability and statistics attached to it.
In fact there are tons of serious players who have no idea what a common denominator is. As complex as Hold'em strategy is, the game at its core is still very simple.
How to Calculate Poker Odds
Pot odds are the odds you're "being offered by the pot" to make your call. This is the amount of money in the pot compared to the amount of money you must pay to stay in the hand.
An example: Say we go to the flop heads-up. There's $10 in the pot and your opponent bets $5.
Since your opponent's bet is now part of the pot, you're being offered $15 for a cost of $5. In ratio form, that's 15:5
To simplify, you always make the right side of your ratio equal to 1 (you'll see why this is easier in a second). So to make the right side equal to 1, divide 5 by itself. 5/5 = 1.
Basic math rules say that whatever you do to one side of a ratio, you must do to the other. So since we divided the right side by 5, we divide the left side by 5. 15/5 = 3.
Your new ratio is 3:1 (If you want to skip a step, you can also just divide the left side by the right side (15/5) to find the left-hand side of the new ratio).
So in this situation, the pot odds are 3:1.
How to Calculate Poker Equity
The next step after figuring out your pot odds is figuring out your equity (your chances of winning the pot compared to your opponent's).
To calculate your equity, take your total number of outs and multiply that number by 4 on the flop (or 2 on the turn). This will give you your chance at winning the pot as a percentage.
So for example if you have a flush draw, you have 9 outs on the flop. 9x4 = 36% chance at making the best hand.
Since we have the pot odds as a ratio, we then need to make that percentage a ratio to compare the two. With 100 possible percentage points, your equity ratio is then 64-36 (64 times you don't make your hand; 36 times you do).
If we use the same ratio shortcut from the pot odds section to get the right side equal to 1, the equity ratio is (64/36):1 or 1.7:1. Meaning for every one time you make your hand there will be 1.7 times that you don't.
If you don't want to be that precise in your pot-odds calculation (and poker math doesn't need to be exact at the table), the simple shortcut is to estimate that 36 will go into 64 a little less than twice.
It really doesn't matter if you think that means it's 1.6, 1.7, 1.8 or 1.9:1; even if you just round it to 2:1 that's probably close enough to decide on making the call or not.
Comparing Pot Odds to Equity
So how do you know if you should make the call? Simply compare the two numbers on the left-hand side of the ratios.
If your pot odds number is higher than your equity number, then it's a good call. If it's lower, then you're making a bad call. In its most basic form, odds are no more complicated than this.

Ballpark Poker Odds are Good Enough
Understanding poker odds in Texas Hold'em might seem like a daunting task - especially if you're not "a math person."
But everybody who plays poker has the ability to calculate poker odds. Everybody.
You don't have to get it dialled in to the fourth decimal place (although if you do end up playing the high stakes that wouldn't hurt) but generally understanding when you're a 60-40 favorite or when you're getting the right odds to call are important things to know.
If you are miscalculating your pot odds (or not thinking about them), you're going to make a lot of mistakes that will make it hard for you to become a winning player.
Comparing your current pot odds with your chances of hitting your outs is critical. But luckily, the math behind it is really quite simple.
