KK against 88: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| KK | 80.681 | 0.380 | 18.939 | 80.871 |
| 88 | 18.939 | 0.380 | 80.681 | 19.129 |
Both hands are pocket pairs: KK and 88. Both hands are pairs, so the bigger pair is ahead on every board that does not pair a card below it.
A gap this wide means 88 is in trouble before the flop and has few good runouts. 0.38% of boards are ties, so the equity of each hand is its win rate plus half of that.
The hand ranking puts KK at 2 and 88 at 7 out of 169 starting hands.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| KK | 49,734,000 | 234,000 | 11,675,000 |
| 88 | 11,675,000 | 234,000 | 49,734,000 |
The total is exact: 36 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| KK | 4.228 | 1.239 | 5.280 | 0.237 |
| 88 | 0.237 | 5.280 | 1.239 | 4.228 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
Who is ahead on which flops
Paired flops are the best for KK (86.45%); low rainbow flops (nine high or lower) are the worst (67.86%). 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 | 88 wins | KK equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 24.595 | 83.407 | 0.214 | 16.379 | 83.514 |
| Rainbow, nine or lower | 6.314 | 67.392 | 0.941 | 31.667 | 67.862 |
| Two-tone | 46.363 | 79.577 | 0.348 | 20.075 | 79.751 |
| Monotone | 5.152 | 74.388 | 1.730 | 23.882 | 75.253 |
| Paired | 17.576 | 86.397 | 0.100 | 13.503 | 86.447 |
A rainbow flop shows three suits, a two-tone flop repeats one suit, a monotone flop is a single suit, and a paired flop repeats a rank.
