It calculates the number of ways of picking 2 cards from a deck of 52 cards if the order of the cards doesn’t matter. Now let’s say you want to know the probability of being dealt aces preflop. We already know there are 1,326 different two-card-combinations. Exactly 6 of those are pocket aces, namely A ♠ A ♥ , A ♠ A ♦ , A ♠ A ♣ , A ♥ A ♦ , A ♥ A ♣ and A ♦ A ♣ .

Just count the number of combinations and divide by the number of total possible preflop combinations. The formulas in the tables above and below show how each probability is calculated. Odds of running into better hands. It is one of the biggest fears poker players have when holding queens or kings before the flop: another player wakes up with aces and takes down the pot. If you are playing against a single opponent those events will occur very rarely. If you’re holding kings for example, the probability of your opponent holding aces is less than 0.5 percent. But the more players there are left to act behind you the more likely it is that one of them has your premium pair beaten. Another example: if you’er holding jacks under the gun at a full ring table, the chances of at least one opponent behind you holding queens or better are already more than 11 percent. The following table shows the probabilities of running into better hands when you’re holding a premium hand and how often you can expect certain scenarios to happen in the long run (e.g. on a full ring table you can expect to be dealt kings and run into aces every 5,737 hands): Probabilities of running into better hands preflop.
