Introduction

Texas Holdem Heads-Up Preflop Odds. This table was created by enumerating through every possible board and opponent hole card combination for each of the 169 texas holdem preflop starting hands. Take, for example, the poker percentages of AK, one of the few extremely powerful hands in Texas Hold’em. Technically, it wins less than a middle pocket pair like 7-7. Aside from all-in heads-up tournament situations A-K is a much stronger hand in real-life scenarios because real-life hands aren’t random hands staying in to showdown.

In Texas Hold 'Em a hand is said to be dominated if another player has a similar, and better, hand. To be more specific, a dominated hand is said to rely on three or fewer outs (cards) to beat the hand dominating it, not counting difficult multiple-card draws. There are four types of domination, as follows.

1. A pair is dominated by a higher pair. For example J-J is dominated by Q-Q. Only two cards help the J-J, the other two jacks.
2. A non-pair is dominated by a pair of either card. For example, Q-5 is dominated by Q-Q or 5-5. In the case of 5-5, three cards only will help the Q-5, the other three queens.
3. A non-pair is dominated by a pair greater than the lower card. For example, Q-5 is dominated by 8-8. Only three cards will help the Q-5, the other three queens.
4. A non-pair is dominated by another non-pair if there if there is a shared card, and the rank of the opponent's non-shared card is greater the dominated non-shared card. For example Q-5 is dominated by K-5 or Q-7. In the former case (K-5 over Q-5) only three cards can help Q-5, the other three queens.

That said, the following tables present the probability of every two-card hand being dominated, according to the total number of players.

Methodology: These tables were created by a random simulation. Each cell in the table above for pairs was based on 7.8 million hands, and 21.7 million for the non-pairs.

2-Player Formula

The probability of domination in a two player game is easy to calculate. For pairs it is 6×(number of higher ranks)/1225. For example, the probability a pair of eights is dominated is 6×6/1225 = 0.0294, because there are six ranks higher than 8 (9,T,J,Q,K,A).

For non-pairs the formula is (6+18×(L-1)+12×H)/1225, where

L=Number of ranks higher than lower card
H=Number of ranks higher than higher card

For example, the probability that J-7 is dominated is (6+18×(7-1)+12×3)/1225 = 150/1225 = 0.1224.

Both before and after the flop in any limit Holdem game, it is helpful to be able to make a reasonably accurate estimate of the types and numbers of playable hands that you are likely to be competing against.

Much of your decision making involves the business of 'putting' opposing players 'on their hands' (or in other words, figuring out what cards they are playing). Experienced Holdem players are often very good at this. An understanding of the types of hands that are most likely to be against you helps prevent both underestimating and overestimating your competition.

Here are some stats that are based on the total possible combinations of various Holdem hole cards that are normally playable.

The five different types of two card Hold'em hands highlighted here are those that are most commonly played. They are not shown in any particular order and within the groups are powerful hands that are almost always played, down to marginal value hands that can be played under certain betting conditions.

The rest of the hands, shown as All Others, are all the very weak hands that most players hardly ever play.
