See how a known card or a board pair changes the count, plus its rank and equity. AJo can be dealt in 12 combos. That is 0.90% of the 1,326 two-card hands, and its 63.56% equity against a random hand ranks it number 15 out of 169. - Combos: 12 - Share of 1,326: 0.90% - Rank of 169: 15 - Equity vs random: 63.56% - This hand and stronger: 7.54% ## AJo: the 12 combos Count every ace and jack pairing (16) and take away the suited ones (4): 12 combos are offsuit. These are the 12 specific hands that count as AJo. Each tile is one two-card holding, and no two tiles are the same hand. The 12 combos of AJo: As Jh, As Jd, As Jc, Ah Js, Ah Jd, Ah Jc, Ad Js, Ad Jh, Ad Jc, Ac Js, Ac Jh, Ac Jd. ## How cards you can see change the count This is the blocker table for AJo. One visible card of a given rank removes the combos that need it, and the rest stay possible. AJo combos left after one known card of each rank: | Known card | AJo combos left | | --- | --- | | Ace | 9 | | King | 12 | | Queen | 12 | | Jack | 9 | | Ten | 12 | | Nine | 12 | | Eight | 12 | | Seven | 12 | | Six | 12 | | Five | 12 | | Four | 12 | | Three | 12 | | Two | 12 | With an ace or a jack in view, 9 of the 12 combos of AJo remain, which removes 25%. Any card of a different rank leaves all 12 combos in play. ## When the board is paired Boards with a pair remove two cards of one rank at once. The rows give the AJo combos left for each paired rank. AJo combos left after a pair of each rank on the board: | Board pair | AJo combos left | | --- | --- | | Aces | 6 | | Kings | 12 | | Queens | 12 | | Jacks | 6 | | Tens | 12 | | Nines | 12 | | Eights | 12 | | Sevens | 12 | | Sixes | 12 | | Fives | 12 | | Fours | 12 | | Threes | 12 | | Twos | 12 | Only a board pair of aces or jacks matters here: 6 combos of AJo remain, against 12 for any other pair. ## A worked example Suppose you look down at an ace and a two. Any opponent hand comes from 1,225 possibilities. AJo makes up 9 of them, which is 0.73% (1 in 136); if you held neither card's rank in common with AJo, it would be 12 of them, 0.98%. ## How strong is AJo? Order all 169 classes by equity against a random hand and AJo lands at number 15, inside the top 30 classes, with 63.56%. A tie is worth half a win in that figure. Down to and including AJo, the ranking holds 100 combos, or 7.54% of deals; 88 of them belong to hands above it. ## AJo against ranges of hands Five ranges, five equities for AJo.

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.
