KJs against KJo: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| KJs | 7.158 | 90.669 | 2.173 | 52.492 |
| KJo | 2.173 | 90.669 | 7.158 | 47.508 |
The matchup pits a suited hand against an offsuit hand. The cards are the same ranks, so any difference in equity comes from suitedness alone.
With only 4.98 points between them, the board decides this matchup far more than the cards in hand. Of every 100 boards, about 90.67 are split pots, and the equity figures already include them.
In the ranking of all 169 starting hands, KJs is number 20 and KJo is number 26.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| KJs | 2,942,000 | 37,261,000 | 893,000 |
| KJo | 893,000 | 37,261,000 | 2,942,000 |
The total is exact: 24 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) |
|---|---|---|---|---|
| KJs | 1.105 | 13.970 | 46.019 | 0.905 |
| KJo | 0.905 | 46.019 | 13.970 | 1.105 |
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
