See how a known card or a board pair changes the count, plus its rank and equity. The answer is 12 combos. 52o covers 0.90% of the 1,326 starting hands and holds rank 166 of 169 on equity against a random hand, 34.28%. - Combos: 12 - Share of 1,326: 0.90% - Rank of 169: 166 - Equity vs random: 34.28% - This hand and stronger: 97.29% ## 52o: the 12 combos Count every five and two pairing (16) and take away the suited ones (4): 12 combos are offsuit. Spelled out, 52o is these 12 holdings. The suits are what separate them from each other, and the ranks are the same in all. The 12 combos of 52o: 5s 2h, 5s 2d, 5s 2c, 5h 2s, 5h 2d, 5h 2c, 5d 2s, 5d 2h, 5d 2c, 5c 2s, 5c 2h, 5c 2d. ## How cards you can see change the count A card in your hand or on the board takes combos away from your opponent's possible hands. This table counts what is left of 52o for each rank of card you can see. 52o combos left after one known card of each rank: | Known card | 52o combos left | | --- | --- | | Ace | 12 | | King | 12 | | Queen | 12 | | Jack | 12 | | Ten | 12 | | Nine | 12 | | Eight | 12 | | Seven | 12 | | Six | 12 | | Five | 9 | | Four | 12 | | Three | 12 | | Two | 9 | With a five or a two in view, 9 of the 12 combos of 52o remain, which removes 25%. Any card of a different rank leaves all 12 combos in play. ## When the board is paired Two board cards of one rank are out of reach for your opponent. The table gives the 52o combos that remain for each paired rank. 52o combos left after a pair of each rank on the board: | Board pair | 52o combos left | | --- | --- | | Aces | 12 | | Kings | 12 | | Queens | 12 | | Jacks | 12 | | Tens | 12 | | Nines | 12 | | Eights | 12 | | Sevens | 12 | | Sixes | 12 | | Fives | 6 | | Fours | 12 | | Threes | 12 | | Twos | 6 | Only a board pair of fives or twos matters here: 6 combos of 52o remain, against 12 for any other pair. ## A worked example Say your hole cards are a five and a three. That leaves 1,225 possible two-card hands for an opponent, and 9 of them are 52o: a 0.73% chance, roughly 1 in 136. Without the five in your hand it would be 12 combos, 0.98%, roughly 1 in 102. ## How strong is 52o? 52o ranks number 166 of the 169 starting-hand classes, among the 30 weakest classes. Against one random hand it has 34.28% equity, which counts a win as 1 and a tie as one half over every five-card board. 1,290 of the 1,326 starting hands are 52o or better by this ranking. That is 97.29% of deals. ## 52o against ranges of hands Tighter ranges are harder to beat. 52o gets 18.49% against the top 5 percent (60 combos), 25.99% against the top 10 percent (130 combos), 29.61% against the top 20 percent (264 combos), 30.68% against the top 30 percent (386 combos) and 31.62% against the top 50 percent (658 combos), and each figure counts every combo your cards leave possible. 52o equity against the strongest hands: | Opponent range | Combos in range | 52o equity | | --- | --- | --- | | Top 5 percent | 60 | 18.49% | | Top 10 percent | 130 | 25.99% | | Top 20 percent | 264 | 29.61% | | Top 30 percent | 386 | 30.68% | | Top 50 percent | 658 | 31.62% | 52o is behind all five of these ranges, even the top 50 percent, so it is the underdog on average against each of them. Check what 52o does to the top 10 percent range of 130 combos: averaged over its 12, 130.00 remain for an opponent. That is no loss at all: 52o blocks none of those hands. ## Hands next to 52o Rank says who is stronger against a random hand; a head-to-head says who is stronger against each other. 52o has 35.46% equity against 72o, the hand ranked number 165: it wins 26.28% of boards, ties 18.36% and loses 55.36%.

Switch 52o from offsuit to suited and you get 52s: 4 combos, rank 155, 37.85% equity. 52o has 3 times as many combos as 52s and is 3.56 points weaker against a random hand.

The known-card rows remove every combo that uses a card of that rank; the board-pair rows remove those that use either of two such cards. Rank and equity read our table of all 169 by 169 preflop matchups, each counted over every one of the 1,712,304 boards. Ties count as half a win, and a range is weighted by its live combos.
