The 30 hands in the top 15 percent
The cut-off rule is simple: take classes in rank order while the total stays within 15 percent, or 198.90 of the 1,326 combos. A6s is left out because 4 more combos would reach 15.08%, so the exact share is 14.78%.
- In the range
- Not in the range
In order, the hands are AA, KK, QQ, JJ, TT, 99, 88, AKs, 77, AQs, AJs, AKo, ATs, AQo, AJo, KQs, 66, A9s, ATo, KJs, A8s, KTs, KQo, A7s, A9o, KJo, 55, QJs, K9s, A5s.
How the combos split
The 30 hands fall into three kinds. Combos per hand differ by kind (6, 4 and 12), so the combo column, not the hand column, shows the true weight of each kind.
| Kind | Hands | Combos | Share of range |
|---|---|---|---|
| Pairs | 10 | 60 | 30.61% |
| Suited hands | 13 | 52 | 26.53% |
| Offsuit hands | 7 | 84 | 42.86% |
Offsuit hands are 42.9% of the range's 196 combos. Pairs add 60, suited hands 52 and offsuit hands 84.
The range by top card
Look at the range through its highest card. For each rank, the table gives the hand count and the combo count out of 196 combos.
| Top card | Hands | Combos |
|---|---|---|
| Ace | 14 | 98 |
| King | 7 | 46 |
| Queen | 2 | 10 |
| Jack | 1 | 6 |
| Ten | 1 | 6 |
| Nine | 1 | 6 |
| Eight | 1 | 6 |
| Seven | 1 | 6 |
| Six | 1 | 6 |
| Five | 1 | 6 |
| Four | 0 | 0 |
| Three | 0 | 0 |
| Two | 0 | 0 |
Hands with an ace on top are 14 of the 30 and 98 of the 196 combos, 50.0%. The lowest top card in the range is the five, with 1 hand and 6 combos.
Hands worth knowing at the edge
The range's last hand is A5s: number 30, 59.92% equity against a random hand. Its first absentee is A6s: number 31, 59.91%.
Compared with the top 10 percent, this range adds 10 hands and 66 combos: A8s, KTs, KQo, A7s, A9o, KJo, 55, QJs, K9s, A5s.
How your cards shrink the range
A known card cannot be in an opponent's hand. The tables count the combos of the top 15 percent that survive one card of each rank, and the ones that survive a full two-card holding.
| Known card | Combos left | Combos removed |
|---|---|---|
| Ace | 170 | 26 |
| King | 179 | 17 |
| Queen | 184 | 12 |
| Jack | 184 | 12 |
| Ten | 188 | 8 |
| Nine | 188 | 8 |
| Eight | 192 | 4 |
| Seven | 192 | 4 |
| Six | 193 | 3 |
| Five | 192 | 4 |
| Four | 196 | 0 |
| Three | 196 | 0 |
| Two | 196 | 0 |
| You hold | Combos left |
|---|---|
| AA | 145 |
| KK | 163 |
| AKs | 154 |
| AKo | 154 |
| 173 | |
| JTs | 176 |
| 77 | 189 |
| A5s | 167 |
| 72o | 192 |
A known ace takes 26 combos out of 196; a known two takes 0. With AA in your hand 145 remain, against 192 with 72o.
A worked example
You hold AKs and your opponent plays the top 15 percent. Of that range's 196 combos, 154 use none of your two cards, so your opponent holds one of 154 hands, and the chance that a random deal of the other 1,225 hands falls in the range is 154 / 1,225 = 12.57%.
How strong the range is as a group
Taken as a whole, the range has 65.92% equity against one random hand, and 61.36% against the top 50 percent. Both figures weight each matchup by the combos that can be dealt together.

Questions about the top 15 percent
- How many hands are in the top 15 percent?
- The top 15 percent is 30 hands and 196 combos, which is 14.78% of the 1,326 two-card hands. It runs from AA down to A5s. A6s is the first hand left out, because 4 more combos would reach 15.08%.
- Why is the top 15 percent really 14.78%?
- Hands go in as whole classes, in rank order, and a class is never split. The range stops at the last class that keeps the total at or under 15 percent, so it lands on 14.78%, 196 of 1,326 combos, rather than exactly 15.
- How many of the combos have an ace in them?
- 14 hands in the range have an ace as the higher card, adding up to 98 of 196 combos, 50.0%. Holding one ace yourself leaves 170 combos of the range possible for an opponent.
How this was computed
Start with the 169 classes ordered by equity against a random hand. Walk down the list adding combos (a pair is 6, a suited hand 4, an offsuit hand 12) and stop before the total passes 15 percent of 1,326.
