JJ

JJ (pocket jacks) wins 77.5% of the time against a single random opponent, which places it 4th out of the 169 starting hands — the top 2.4% of the range. At a six-handed table (five opponents) its equity falls to 33.7% and its rank moves to 4; nine-handed (eight opponents) it holds 21.7% for rank 5. A middle pair — frequently chased by two overcards.

As a pocket pair there is no suited twin; instead there are 6 combinations of it in the deck, so you are dealt it 0.45% of the time (6 of 1,326 two-card hands). The hand ranked one place above is QQ at 79.9% and one place below is TT at 75.1%. Every pocket pair flops a set about 11.8% of the time, so the pecking order among pairs is decided almost entirely before the flop.

Played heads-up against each of the other 168 hands, JJ is a favourite against 165 of them and an underdog against 3. Its best matchup is J2o at 94.0% and its worst is QQ at 18.1% — a spread of 75.9 points, which is why calling JJ simply "strong" or "weak" says very little.

JJ shares a rank with relatively few hands, so it is rarely on the wrong side of a kicker problem. What does hurt it is running into a higher pair, where the number bottoms out at 18.1%. The table further down lists all 168 opponents individually.

Within the 13 pocket pairs it comes 4 of 13. The strongest hand in that group, AA, is 7.7 points away, and the weakest, 22, sits 27.3 points below. Measured against the average equity of all 169 hands, 51%, JJ lands +26.5 points from the middle of the pack, and 3 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 77.5% against one opponent, 61.4% against two, 40.2% against four and 21.7% against eight. That last figure is 195% of an even nine-way share (11.1%). The Chen formula scores this hand at 12 points, and it arrives 0.45% of the time (6 of 1,326 combinations).

One caveat worth repeating: every number on this page assumes the opponent holds a completely random hand and that the pot goes to showdown. Real opponents hold ranges, and a range that has already put money in is stronger than random — which is exactly why JJ reads as 77.5% here but plays worse than that against a raise. Use the 168 rows in the table below to see which specific holdings are the problem, rather than treating the headline figure as a verdict on the hand.
