JJ against J9s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| JJ | 82.861 | 2.158 | 14.981 | 83.940 |
| J9s | 14.981 | 2.158 | 82.861 | 16.060 |
JJ and J9s are a pocket pair and a suited hand, in that order. The non-pair hand shares a rank with the pair, so two of its outs for pairing are blocked by the pair itself.
A gap this wide means J9s is in trouble before the flop and has few good runouts. 2.16% of boards are ties, so the equity of each hand is its win rate plus half of that.
Place 4 of 169 belongs to JJ and place 55 belongs to J9s in the ranking against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| JJ | 17,026,000 | 443,000 | 3,078,000 |
| J9s | 3,078,000 | 443,000 | 17,026,000 |
The total is exact: 12 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) |
|---|---|---|---|---|

| J9s | 0.191 | 6.675 | 1.207 | 5.227 |
The final column gives the least the pot must offer for each unit called for a call to break even at this equity.
