See how a known card or a board pair changes the count, plus its rank and equity. There are 12 combos of T7o, which is 0.90% of the 1,326 two-card hands a 52-card deck can deal. It ranks number 101 of 169 hand classes, with 47.91% equity against a random hand. - Combos: 12 - Share of 1,326: 0.90% - Rank of 169: 101 - Equity vs random: 47.91% - This hand and stronger: 56.56% ## T7o: the 12 combos For T7o, there are 4 tens and 4 sevens, so 16 pairings, and the 4 that share a suit belong to the suited hand. That leaves 12. The 12 holdings of T7o are listed below, higher card first. Nothing is left out and nothing appears twice. The 12 combos of T7o: Ts 7h, Ts 7d, Ts 7c, Th 7s, Th 7d, Th 7c, Td 7s, Td 7h, Td 7c, Tc 7s, Tc 7h, Tc 7d. ## How cards you can see change the count Combos shrink when cards are visible. The rows below give the T7o count left after one known card of each rank, from the ace down to the two. T7o combos left after one known card of each rank: | Known card | T7o combos left | | --- | --- | | Ace | 12 | | King | 12 | | Queen | 12 | | Jack | 12 | | Ten | 9 | | Nine | 12 | | Eight | 12 | | Seven | 9 | | Six | 12 | | Five | 12 | | Four | 12 | | Three | 12 | | Two | 12 | A ten or a seven 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 T7o that are still possible after a board pair of each rank. T7o combos left after a pair of each rank on the board: | Board pair | T7o combos left | | --- | --- | | Aces | 12 | | Kings | 12 | | Queens | 12 | | Jacks | 12 | | Tens | 6 | | Nines | 12 | | Eights | 12 | | Sevens | 6 | | Sixes | 12 | | Fives | 12 | | Fours | 12 | | Threes | 12 | | Twos | 12 | Pairing tens or sevens on the board cuts T7o to 6 combos. Every other paired board leaves the full 12. ## A worked example Walk through it once. Your hole cards: a ten and a two. Your opponent's possible hands: 1,225. Of those, T7o 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 T7o? The ranking puts T7o at number 101 out of 169, below the middle of the ranking. Its equity against a random hand is 47.91%, with a tie counted as half a win. A range that runs from the top of the ranking down to T7o is 750 combos, 56.56% of all two-card hands, and 738 of them rank above T7o itself. ## T7o against ranges of hands Here is how T7o fares against five ranges that run from the top of the ranking down. It scores 23.02% against the top 5 percent (60 combos), 29.09% against the top 10 percent (130 combos), 31.95% against the top 20 percent (264 combos), 34.15% against the top 30 percent (386 combos) and 36.12% against the top 50 percent (658 combos). T7o equity against the strongest hands: | Opponent range | Combos in range | T7o equity | | --- | --- | --- | | Top 5 percent | 60 | 23.02% | | Top 10 percent | 130 | 29.09% | | Top 20 percent | 264 | 31.95% | | Top 30 percent | 386 | 34.15% | | Top 50 percent | 658 | 36.12% | T7o 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 T7o in your hand, an average of 120.00 are left. That is 10.00 combos fewer than the 130 an opponent has before you look. ## Hands next to T7o Rank is a number on a list, and the matchups with the neighbours show how close or far apart the hands really are.
