See how a known card or a board pair changes the count, plus its rank and equity. Count 12 combos for 84o: 0.90% of the 1,326 starting hands you can be dealt. Ranked by equity against a random hand (39.45%), it is number 148 of 169. - Combos: 12 - Share of 1,326: 0.90% - Rank of 169: 148 - Equity vs random: 39.45% - This hand and stronger: 84.62% ## 84o: the 12 combos An offsuit hand pairs any eight with any four 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 84o. When a range chart marks 84o, it marks all of them together. The 12 combos of 84o: 8s 4h, 8s 4d, 8s 4c, 8h 4s, 8h 4d, 8h 4c, 8d 4s, 8d 4h, 8d 4c, 8c 4s, 8c 4h, 8c 4d. ## How cards you can see change the count How many 84o 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. 84o combos left after one known card of each rank: | Known card | 84o combos left | | --- | --- | | Ace | 12 | | King | 12 | | Queen | 12 | | Jack | 12 | | Ten | 12 | | Nine | 12 | | Eight | 9 | | Seven | 12 | | Six | 12 | | Five | 12 | | Four | 9 | | Three | 12 | | Two | 12 | Holding an eight or a four takes 84o 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 84o count for each possible pair on the board. 84o combos left after a pair of each rank on the board: | Board pair | 84o combos left | | --- | --- | | Aces | 12 | | Kings | 12 | | Queens | 12 | | Jacks | 12 | | Tens | 12 | | Nines | 12 | | Eights | 6 | | Sevens | 12 | | Sixes | 12 | | Fives | 12 | | Fours | 6 | | Threes | 12 | | Twos | 12 | Eights or fours paired on the board leave 6 combos of 84o, and no other pair changes the count of 12. ## A worked example Here is the count in a real spot. You hold an eight and a two, which leaves 1,225 hands for your opponent. 84o is 9 of them, a 0.73% chance. A hand with no eight in it would give 12 combos, 0.98%. ## How strong is 84o? Number 148 of 169: that is where 84o sits when hands are ordered by equity against a random hand, among the 30 weakest classes. The figure is 39.45%, wins plus half the ties. Counting from the top, 84o is where the running total reaches 1,122 combos (84.62% of 1,326). The 1,110 combos before it are all stronger classes. ## 84o against ranges of hands Equity against a range is a weighted average of the matchups with every hand in it. The numbers for 84o: 18.93% against the top 5 percent (60 combos), 26.65% against the top 10 percent (130 combos), 29.54% against the top 20 percent (264 combos), 30.75% against the top 30 percent (386 combos) and 32.60% against the top 50 percent (658 combos). 84o equity against the strongest hands: | Opponent range | Combos in range | 84o equity | | --- | --- | --- | | Top 5 percent | 60 | 18.93% | | Top 10 percent | 130 | 26.65% | | Top 20 percent | 264 | 29.54% | | Top 30 percent | 386 | 30.75% | | Top 50 percent | 658 | 32.60% | 84o is behind all five of these ranges, even the top 50 percent, so it is the underdog on average against each of them. How much of the top 10 percent can an opponent still hold? Across the 12 combos of 84o you might hold, 127.00 of its 130 combos remain on average. That is 3.00 combos fewer than the 130 an opponent has before you look. ## Hands next to 84o The hands on either side of 84o in the ranking make a useful pair of comparisons. 84o has 57.87% equity against 63s, the hand ranked number 147: it wins 55.45% of boards, ties 4.82% and loses 39.72%.
