See how a known card or a board pair changes the count, plus its rank and equity. Count 12 combos for J6o: 0.90% of the 1,326 starting hands you can be dealt. Ranked by equity against a random hand (47.84%), it is number 102 of 169. - Combos: 12 - Share of 1,326: 0.90% - Rank of 169: 102 - Equity vs random: 47.84% - This hand and stronger: 57.47% ## J6o: the 12 combos An offsuit hand pairs any jack with any six of a different suit: 4 x 4 = 16 pairings, minus the 4 suited ones, leaves 12. Below are the 12 exact two-card holdings in J6o. When a range chart marks J6o, it marks all of them together. The 12 combos of J6o: Js 6h, Js 6d, Js 6c, Jh 6s, Jh 6d, Jh 6c, Jd 6s, Jd 6h, Jd 6c, Jc 6s, Jc 6h, Jc 6d. ## How cards you can see change the count How many J6o combos can an opponent still hold? It depends on the cards you can see, and the table gives the answer for one card of each rank. J6o combos left after one known card of each rank: | Known card | J6o combos left | | --- | --- | | Ace | 12 | | King | 12 | | Queen | 12 | | Jack | 9 | | Ten | 12 | | Nine | 12 | | Eight | 12 | | Seven | 12 | | Six | 9 | | Five | 12 | | Four | 12 | | Three | 12 | | Two | 12 | Holding a jack or a six takes J6o from 12 combos down to 9, a cut of 25%. Any card of a different rank leaves all 12 combos in play. ## When the board is paired Board pairs take away more combos than a single card does. The table lists the J6o count for each possible pair on the board. J6o combos left after a pair of each rank on the board: | Board pair | J6o combos left | | --- | --- | | Aces | 12 | | Kings | 12 | | Queens | 12 | | Jacks | 6 | | Tens | 12 | | Nines | 12 | | Eights | 12 | | Sevens | 12 | | Sixes | 6 | | Fives | 12 | | Fours | 12 | | Threes | 12 | | Twos | 12 | Jacks or sixes paired on the board leave 6 combos of J6o, and no other pair changes the count of 12. ## A worked example Here is the count in a real spot. You hold a jack and a two, which leaves 1,225 hands for your opponent. J6o is 9 of them, a 0.73% chance. A hand with no jack in it would give 12 combos, 0.98%. ## How strong is J6o? Number 102 of 169: that is where J6o sits when hands are ordered by equity against a random hand, below the middle of the ranking. The figure is 47.84%, wins plus half the ties. Counting from the top, J6o is where the running total reaches 762 combos (57.47% of 1,326). The 750 combos before it are all stronger classes. ## J6o against ranges of hands Equity against a range is a weighted average of the matchups with every hand in it. The numbers for J6o: 22.28% against the top 5 percent (60 combos), 27.12% against the top 10 percent (130 combos), 30.36% against the top 20 percent (264 combos), 32.11% against the top 30 percent (386 combos) and 34.79% against the top 50 percent (658 combos). J6o equity against the strongest hands: | Opponent range | Combos in range | J6o equity | | --- | --- | --- | | Top 5 percent | 60 | 22.28% | | Top 10 percent | 130 | 27.12% | | Top 20 percent | 264 | 30.36% | | Top 30 percent | 386 | 32.11% | | Top 50 percent | 658 | 34.79% | J6o is behind all five of these ranges, even the top 50 percent, so it is the underdog on average against each of them.
