KK against 66: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| KK | 80.315 | 0.355 | 19.330 | 80.492 |
| 66 | 19.330 | 0.355 | 80.315 | 19.508 |
KK and 66 are both pocket pairs. Two pairs against each other is a one-way street: the lower pair needs one of its two remaining cards.
A gap this wide means 66 is in trouble before the flop and has few good runouts. 0.36% of boards are ties, so the equity of each hand is its win rate plus half of that.
Place 2 of 169 belongs to KK and place 17 belongs to 66 in the ranking against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |

The board total is exact, 36 deals at 1,712,304 boards each. Won, tied and lost counts are rounded to the nearest thousand from the five-decimal percentages.

| 66 | 0.242 | 5.173 | 1.245 | 4.126 |
The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity.
Who is ahead on which flops
Split by what the flop looks like, KK peaks at 86.45% on paired flops and bottoms out at 65.03% on low rainbow flops (nine high or lower). KK stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.
| Flop | Share of flops | KK wins | Ties | 66 wins | KK equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 24.595 | 83.537 | 0.201 | 16.262 | 83.637 |

| Monotone | 5.152 | 74.054 | 1.760 | 24.186 | 74.934 |
| Paired | 17.576 | 86.395 | 0.100 | 13.505 | 86.445 |
