QQ vs JJ Odds
Last updated: May 23, 2026
Pocket Queens (QQ) wins 80.8% of the time against Pocket Jacks (JJ) preflop. JJ wins 19.2% — almost entirely by flopping a set of jacks. QQ is a 4.21-to-1 favorite once the chips go in. This is the classic 4-bet cooler: QQ opens UTG, JJ 3-bets from middle position, QQ 4-bets, JJ stacks off — and discovers it was an 80/20 dog the whole time. The matchup is functionally identical to QQ vs TT and QQ vs 99 because the underdog always holds exactly 2 outs.
The Exact Number: 80.8% vs 19.2%
QQ wins 80.8% of all 5-card runouts following a QQ vs JJ preflop all-in. JJ wins 19.2%, ties are rounding-error rare. The 4.21-to-1 favorite ratio is one of the most stable equity numbers in poker — it does not depend on stack depth, position, or any betting action.

Does the Suit Matter?
The suits of QQ and JJ shift equity by at most 0.4 percentage points. QQ blocking both of JJ's suits removes some of JJ's runner-runner flush equity. In practice, you can treat the matchup as 80.8/19.2 regardless of suit configuration.

Post-Flop: When Does the Equity Flip?
The only realistic equity-flip is a jack on the flop. When that happens, JJ becomes a 94% favorite with a flopped set, and QQ needs runner-runner queens or a straight to recover. Without a jack, QQ stays near 90% on most flops — even overcard boards barely dent QQ's edge because JJ still only has 2 clean outs.

Why Is QQ a 4.21-to-1 Favorite?
JJ has exactly 2 outs in the deck — the two remaining jacks. Over 5 community cards, that's about a 16.5% chance of flopping or running into a set. The remaining ~2.7% of JJ's equity comes from runner-runner straights (involving 8-9-T-K, etc.) and rare runner-runner flushes when QQ blocks one suit.

How to Play QQ vs JJ in 4-Bet Spots
QQ vs JJ is the canonical 4-bet pot situation. Whether JJ should stack off depends entirely on the 4-better's range:
JJ vs a tight 4-bet range {AA, KK, QQ, AK}
JJ has roughly 36% equity. At 100bb deep, stacking off is unprofitable. Fold to a small 4-bet, consider a call only with strong implied odds or set-mining potential.
JJ vs a wider 4-bet range including AQs, AJs, KQs
JJ equity climbs to ~50%+. Calling becomes correct; shoving is often best at shallow stack depths (~50bb).
QQ as the 4-better — almost always shove or call
QQ has 80%+ equity against any pocket pair below it and 60%+ vs broadway hands. Stack off freely; only consider folding to a 5-bet from a player whose range is {AA, KK only}.

Frequently Asked Questions
What are the exact odds of QQ vs JJ preflop?
QQ wins approximately 80.8% of the time, JJ wins 19.2%, and ties happen less than 0.5% of hands. The figure is derived from full enumeration of all possible 5-card board runouts. QQ is a 4.21-to-1 favorite — one of the most lopsided premium-vs-premium matchups in Texas Hold'em.
Does suit affect QQ vs JJ equity?
Barely. The largest swing across all suit combinations is about 0.3-0.4 percentage points. QQ blocking both of JJ's suits (e.g. Q♠Q♥ vs J♠J♥) gives the maximum edge at ~81.0%. JJ with no shared suits sits at ~19.1%. For practical purposes, treat QQ vs JJ as 80.8/19.2 regardless of suit.
Should JJ ever fold preflop against a QQ 4-bet?
Often, yes. JJ as a 4-bet calling or shoving hand at 100bb deep is marginal at best. Against a typical tight 4-bet range like {AA, KK, QQ, AK}, JJ has only ~36% equity — not enough to profitably stack off. Solver analysis confirms JJ is usually a fold to a small 4-bet against tight ranges. At deeper stacks or vs wider 4-bet ranges, calling becomes viable.
How often does QQ run into JJ?
Both QQ and JJ are dealt 1 in 221 hands (0.45%). The probability of two specific opponents holding QQ and JJ on the same deal is roughly 1 in 22,100. In a 9-handed game, the chance that QQ faces any JJ at the table is approximately 1 in 2,500 hands — uncommon, but every regular player encounters this matchup hundreds of times in a career.
How is QQ vs JJ different from QQ vs TT or QQ vs 99?
Almost identical. QQ vs JJ is 80.8% / 19.2%. QQ vs TT is 80.3% / 19.7%. QQ vs 99 is 80.3% / 19.7%. The underdog always has exactly 2 outs (the remaining pair) and ~17-18% equity from a set, plus another 1-2% from runner-runner straights or flushes. Any pair-over-pair matchup with no shared suits sits in the 80/20 range.
