See how a known card or a board pair changes the count, plus its rank and equity. 4 combos make up Q5s, and the whole deck holds 1,326 two-card hands, so you are dealt it 0.30% of the time. It is number 72 of the 169 classes at 52.77% equity against a random hand. - Combos: 4 - Share of 1,326: 0.30% - Rank of 169: 72 - Equity vs random: 52.77% - This hand and stronger: 39.22% ## Q5s: the 4 combos There is one queen-five pairing per suit, and a suited hand counts each suit once, so Q5s is 4 combos. All 4 ways to hold Q5s are shown here, one tile each. Counting them is how a range gets its size. The 4 combos of Q5s: Qs 5s, Qh 5h, Qd 5d, Qc 5c. ## How cards you can see change the count Every card you can see is a card nobody else can hold. The table shows how many of the 4 combos of Q5s are still possible when you hold one card of each rank, and the same count applies when that card is on the board. Q5s combos left after one known card of each rank: | Known card | Q5s combos left | | --- | --- | | Ace | 4 | | King | 4 | | Queen | 3 | | Jack | 4 | | Ten | 4 | | Nine | 4 | | Eight | 4 | | Seven | 4 | | Six | 4 | | Five | 3 | | Four | 4 | | Three | 4 | | Two | 4 | Only two ranks change the count: a queen or a five leaves 3 combos, 25% fewer. Any card of a different rank leaves all 4 combos in play. ## When the board is paired How does a paired board change the count? For Q5s, the rows below show the combos left after the board pairs each rank in turn. Q5s combos left after a pair of each rank on the board: | Board pair | Q5s combos left | | --- | --- | | Aces | 4 | | Kings | 4 | | Queens | 2 | | Jacks | 4 | | Tens | 4 | | Nines | 4 | | Eights | 4 | | Sevens | 4 | | Sixes | 4 | | Fives | 2 | | Fours | 4 | | Threes | 4 | | Twos | 4 | A board pair of queens or fives leaves 2 combos of Q5s; a pair of any other rank leaves all 4. ## A worked example Worked example: your cards are a queen and a two, so 1,225 two-card hands remain for your opponent. Of those, 3 are Q5s, a 0.24% chance (about 1 in 408). With two cards that do not touch Q5s, it would be 4 combos and 0.33%. ## How strong is Q5s? Q5s holds rank 72 among the 169 classes, in the middle of the ranking. Against a random hand it has 52.77% equity: wins in full, ties as half, every board counted. 516 combos rank above Q5s, and with its own 4 the running total is 520, 39.22% of the 1,326 hands. ## Q5s against ranges of hands Take the strongest hands in rank order and ask how Q5s does against them. The answers, with live combos as weights: 28.08% against the top 5 percent (60 combos), 32.20% against the top 10 percent (130 combos), 34.55% against the top 20 percent (264 combos), 36.21% against the top 30 percent (386 combos) and 40.80% against the top 50 percent (658 combos). Q5s equity against the strongest hands: | Opponent range | Combos in range | Q5s equity | | --- | --- | --- | | Top 5 percent | 60 | 28.08% | | Top 10 percent | 130 | 32.20% | | Top 20 percent | 264 | 34.55% | | Top 30 percent | 386 | 36.21% | | Top 50 percent | 658 | 40.80% | Q5s is behind all five of these ranges, even the top 50 percent, so it is the underdog on average against each of them. Your cards matter to the opponent's range too: with Q5s, 122.00 of the 130 top-10-percent combos survive on average. That is 8.00 combos fewer than the 130 an opponent has before you look. ## Hands next to Q5s Two quick matchups show where Q5s stands among its neighbours.

With a two as your other card, an opponent has it about 1 time in 408. **Is Q5s stronger than Q5o?** Yes, by 2.65 points: Q5s has 52.77% equity against a random hand and ranks number 72, while Q5o has 50.12% and ranks number 89.

Removing the combos that use known cards gives each blocker and board-pair row, with nothing estimated. Our preflop table counts every board (1,712,304 of them) for each pair of classes, so rank and equity here are exact. Ties are halves; ranges are weighted by live combos.
