Playing poker is about playing the odds. The following list gives the odds for outcomes in Texas Hold’em hands. When you realize how heavily the odds are stacked against you, you may want to rethink going all-in before the flop with two suited cards. Use the odds to your advantage:

Calculating the odds of a straight flush overall depends on the number of different combinations of three cards that provide a straight flush, so it’s important to know what your ‘outs’ are. Generally, the odds of forming a straight flush are 1 in 6,180,020, or 4.62%. The primary reason for this page was to assist with bad beat probabilities in a two-player game, for example the Bad Beat Bonus in Ultimate Texas Hold 'Em. For example, if you wish to know the probability of a particular player getting a full house and losing to a four of a kind, we can see from table 7 that there are 966,835,584 such combinations.

• 1 percent (1-in-100): Percentage of time that no player holds an Ace or a King at a table in a 10-handed game

• 1 percent (1-in-100): Percentage of time that if you hold two suited cards, you’ll flop a flush

• 6 percent (about 1-in-20): Percentage of time that five community cards will give pocket suited cards a flush

• 6 percent (about 1-in-20): Percentage of time that you’ll be dealt a pocket pair

• 8 percent (about 1-in-12): Percentage of time that you’ll hit at least trips after having a pair on the flop

• 12 percent (about 1-in-8): Percentage of time that you’ll flop trips if holding a pocket pair

• 12 percent (about 1-in-8): Percentage of time that two more cards will flop in the same suit as a suited pocket pair

• 19 percent (about 1-in-5): Percentage of time that the five community cards will at least trip your pocket pair

• 32 percent (about 1-in-3): Percentage of time that you’ll pair one of your cards on the flop (with no pocket pair)

• 33 percent (about 1-in-3): Percentage of time that you’ll make a full house or better after having trips on the flop

• 35 percent (about 1-in-3): Percentage of time that you’ll make a flush on the turn or river if you have four cards to a flush after the flop

• 8-to-1 12.00% Inside Straight 4 400-to-1 0.25% Overcards 6 118-to-1 0.85% Open-ended Straight 8 9-to-1 10.90% Four Flush 9 15-to-1 6.50% Straight & Flush Draw Straight / Flush or Better 15 Three of a Kind Hope to Make Full House Suited connectors Two suited cards flop a four flush (flush draw) Connected cards, 10 or better Any pair One or more Aces.

Straight flush — Each straight flush is uniquely determined by its highest ranking card; these ranks go from 5 (A-2-3-4-5) up to A (10-J-Q-K-A) in each of the 4 suits. For any particular suit where the straight flush is ace-high, the extra 2 cards may be chosen from the remaining 47 cards.

Introduction

This page examines the probabilities of each final hand of an arbitrary player, referred to as player two, given the poker value of the hand of the other player, referred to as player one. Combinations shown are out of a possible combin(52,5)×combin(47,2)×combin(45,2) = 2,781,381,002,400. The primary reason for this page was to assist with bad beat probabilities in a two-player game, for example the Bad Beat Bonus in Ultimate Texas Hold 'Em.

For example, if you wish to know the probability of a particular player getting a full house and losing to a four of a kind, we can see from table 7 that there are 966,835,584 such combinations. The same table shows us that given that player one has a full house, the probability of losing to a four of a kind is 0.013390. To get the probability before any cards are dealt, divide 966,835,584 by the total possible combinations of 2,781,381,002,400, which yields 0.0002403.

Table 1 shows the number of combinations for each hand of a second player, given that the first player has less than a pair.
