62s: the 4 combos
A suited hand needs both cards in one suit, so each of the 4 suits gives exactly 1 combo: 4 in all.
Here is every one of the 4 combos, written as the two cards you would see. Clubs, diamonds, hearts and spades each appear in the way the count above requires.
How cards you can see change the count
Seeing a card changes which hands are possible. Here is the count of 62s combos that remain after you hold, or the board shows, one card of each rank.
| Known card | 62s combos left |
|---|---|
| Ace | 4 |
| King | 4 |
| Queen | 4 |
| Jack | 4 |
| Ten | 4 |
| Nine | 4 |
| Eight | 4 |
| Seven | 4 |
| Six | 3 |
| Five | 4 |
| Four | 4 |
| Three | 4 |
| Two | 3 |
Holding a six or a two takes 62s from 4 combos down to 3, a cut of 25%. Any card of a different rank leaves all 4 combos in play.
When the board is paired
A paired board shows two cards of one rank, and those two cards cannot be in an opponent's hand either. The table shows the 62s combos left when the board holds a pair of each rank.
| Board pair | 62s combos left |
|---|---|
| Aces | 4 |
| Kings | 4 |
| Queens | 4 |
| Jacks | 4 |
| Tens | 4 |
| Nines | 4 |
| Eights | 4 |
| Sevens | 4 |
| Sixes | 2 |
| Fives | 4 |
| Fours | 4 |
| Threes | 4 |
| Twos | 2 |
Sixes or twos paired on the board leave 2 combos of 62s, and no other pair changes the count of 4.
A worked example
You hold a six and a three. Your opponent's hand is one of 1,225 equally likely two-card holdings. 3 of them are 62s, which is 0.24%, or about 1 in 408. If your two cards had nothing to do with 62s, the same hand would have 4 combos and a 0.33% chance, about 1 in 306.
How strong is 62s?
Measured against a random hand, 62s has 37.67% equity and the number 156 spot of 169, among the 30 weakest classes. Wins count once and ties count half.
Together with all stronger classes, 62s covers 1,186 combos, which is 89.44% of the 1,326 starting hands.
62s against ranges of hands
Against a range, equity is averaged over every hand in it, weighted by how many combos of each hand are still possible. 62s makes 20.81% against the top 5 percent (60 combos), 28.63% against the top 10 percent (130 combos), 32.38% against the top 20 percent (264 combos), 33.51% against the top 30 percent (386 combos) and 34.42% against the top 50 percent (658 combos).
| Opponent range | Combos in range | 62s equity |
|---|---|---|
| Top 5 percent | 60 | 20.81% |
| Top 10 percent | 130 | 28.63% |
| Top 20 percent | 264 | 32.38% |
| Top 30 percent | 386 | 33.51% |
| Top 50 percent | 658 | 34.42% |
62s is behind all five of these ranges, even the top 50 percent, so it is the underdog on average against each of them.
Your own cards block part of an opponent's strong range. The top 10 percent holds 130 combos, and when you hold a combo of 62s an average of 127.00 of them stay possible. That is 3.00 combos fewer than the 130 an opponent has before you look.
