See how a known card or a board pair changes the count, plus its rank and equity. There are 12 combos of 83o, which is 0.90% of the 1,326 two-card hands a 52-card deck can deal. It ranks number 157 of 169 hand classes, with 37.48% equity against a random hand. - Combos: 12 - Share of 1,326: 0.90% - Rank of 169: 157 - Equity vs random: 37.48% - This hand and stronger: 90.35% ## 83o: the 12 combos For 83o, there are 4 eights and 4 threes, so 16 pairings, and the 4 that share a suit belong to the suited hand. That leaves 12. The 12 holdings of 83o are listed below, higher card first. Nothing is left out and nothing appears twice. The 12 combos of 83o: 8s 3h, 8s 3d, 8s 3c, 8h 3s, 8h 3d, 8h 3c, 8d 3s, 8d 3h, 8d 3c, 8c 3s, 8c 3h, 8c 3d. ## How cards you can see change the count Combos shrink when cards are visible. The rows below give the 83o count left after one known card of each rank, from the ace down to the two. 83o combos left after one known card of each rank: | Known card | 83o combos left | | --- | --- | | Ace | 12 | | King | 12 | | Queen | 12 | | Jack | 12 | | Ten | 12 | | Nine | 12 | | Eight | 9 | | Seven | 12 | | Six | 12 | | Five | 12 | | Four | 12 | | Three | 9 | | Two | 12 | An eight or a three you can see leaves 9 of 12, so 25% of the combos are gone. Any card of a different rank leaves all 12 combos in play. ## When the board is paired Now put two cards of the same rank on the board. This table counts the combos of 83o that are still possible after a board pair of each rank. 83o combos left after a pair of each rank on the board: | Board pair | 83o combos left | | --- | --- | | Aces | 12 | | Kings | 12 | | Queens | 12 | | Jacks | 12 | | Tens | 12 | | Nines | 12 | | Eights | 6 | | Sevens | 12 | | Sixes | 12 | | Fives | 12 | | Fours | 12 | | Threes | 6 | | Twos | 12 | Pairing eights or threes on the board cuts 83o to 6 combos. Every other paired board leaves the full 12. ## A worked example Walk through it once. Your hole cards: an eight and a two. Your opponent's possible hands: 1,225. Of those, 83o is 9, so the chance is 9 / 1,225 = 0.73%. With no blocking card it would be 12 / 1,225 = 0.98%. ## How strong is 83o? The ranking puts 83o at number 157 out of 169, among the 30 weakest classes. Its equity against a random hand is 37.48%, with a tie counted as half a win. A range that runs from the top of the ranking down to 83o is 1,198 combos, 90.35% of all two-card hands, and 1,186 of them rank above 83o itself. ## 83o against ranges of hands Here is how 83o fares against five ranges that run from the top of the ranking down. It scores 17.36% against the top 5 percent (60 combos), 25.20% against the top 10 percent (130 combos), 28.07% against the top 20 percent (264 combos), 29.17% against the top 30 percent (386 combos) and 30.84% against the top 50 percent (658 combos). 83o equity against the strongest hands: | Opponent range | Combos in range | 83o equity | | --- | --- | --- | | Top 5 percent | 60 | 17.36% | | Top 10 percent | 130 | 25.20% | | Top 20 percent | 264 | 28.07% | | Top 30 percent | 386 | 29.17% | | Top 50 percent | 658 | 30.84% | 83o is behind all five of these ranges, even the top 50 percent, so it is the underdog on average against each of them. The top 10 percent is 130 combos before you look at your cards. With 83o in your hand, an average of 127.00 are left. That is 3.00 combos fewer than the 130 an opponent has before you look. ## Hands next to 83o Rank is a number on a list, and the matchups with the neighbours show how close or far apart the hands really are. 83o has 57.84% equity against 62s, the hand ranked number 156: it wins 55.42% of boards, ties 4.84% and loses 39.74%.
