KK against 43s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| KK | 79.295 | 0.482 | 20.223 | 79.536 |
| 43s | 20.223 | 0.482 | 79.295 | 20.464 |
One side is a pocket pair, the other is a suited hand. The pair outranks both of the other hand's cards, which is why the pair is a strong favorite.
A lead of 59.08 points is large but not decisive: 43s still takes about 202 of every 1,000 deals. Ties are 0.48% of the outcomes here; each tied board gives both hands half the pot.
KK ranks number 2 of 169 starting hands, and 43s ranks number 150, by equity against a random hand.

Who is ahead on which flops
Rainbow flops topped by a ten or better are the best for KK (84.48%); low rainbow flops (nine high or lower) are the worst (68.32%). 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 | 43s wins | KK equity |
|---|---|---|---|---|---|
| Rainbow, ten or higher | 24.595 | 84.351 | 0.247 | 15.402 | 84.475 |
| Rainbow, nine or lower | 6.314 | 67.711 | 1.225 | 31.064 | 68.323 |

| Monotone | 5.212 | 72.890 | 2.605 | 24.505 | 74.193 |
| Paired | 17.334 | 83.200 | 0.092 | 16.708 | 83.246 |
