AK vs QQ: Who Wins the Classic Preflop Race

Pocket queens are ahead of ace-king before the flop, every single time. A♠K♠ wins about 46% against Q♥Q♦, and A♠K♥ wins about 43%. Everyone calls this a coin flip, and it is not one — 57/43 means the queens take three extra pots out of every twenty-five. That gap decides who is delighted to get 100bb in and who is only doing it because folding is worse.

The real numbers

The matchup has two versions, and the suits are what separate them.

Matchup	AK equity	Pair equity
A♠K♠ vs Q♥Q♦	~46%	~54%
A♠K♥ vs Q♥Q♦	~43%	~57%
A♠K♠ vs 2♥2♦	~50%	~50%

Against queens, ace-king is a slight dog, never a flip: roughly 46% suited and 43% offsuit.

The third row is the one that catches people out. Ace-king fares better against deuces than against queens, even though deuces are the far weaker holding. High cards counterfeit a small pair and leave your ace playing as a kicker, whereas nothing a board does demotes a pair of queens except an ace or a king — which is the card you needed anyway.

Why suited is worth three points

The entire gap between 46% and 43% is the flush.

A suited hand flops a flush draw about one time in nine, and roughly a third of those get there by the river. Add the backdoor runouts and the hands where a flush beats a set of queens, and you have your three points.

Three points sounds trivial. It is not. Getting 100bb in builds a 200bb pot, so three points of equity is 6bb of expected value, collected every time the spot arrives — several times a session for anyone playing volume.

This is why suited and offsuit ace-king behave like different hands in a re-raised pot. Solvers 5-bet the suited version more freely and lean towards calling or folding the offsuit one as stacks get shallower.

Where the 43% comes from

Ace-king is behind until the board helps it, and the board is more generous than it feels in the moment.

Two unpaired cards flop at least a pair about a third of the time. That single fact is most of your equity. Hit an ace or a king on the flop and the overpair that was crushing you is suddenly the hand with two outs.

When the flop misses, you have six outs. The rule of 4 puts six outs at roughly 24% across the turn and river, so even a bricked flop leaves you with about a quarter of an all-in pot.

Those two routes do not stack as neatly as players hope. An ace on the flop is only good news while the queens fail to improve, and a set arriving on the turn takes the whole hand back. The 43% already prices in those reversals, along with the runouts where the board counterfeits both hands and the pot is chopped. Treat it as a finished figure, not a floor to build on.

Getting ace-king in before the flop

You will almost never know you are up against exactly QQ, and that is the whole point.

The spot only arises after a re-raising war, so it pays to be precise about what a 4-bet is before you build a stack-off range around one. When your 4-bet gets shoved on, the question is not whether you beat queens. You do not. The question is what the entire shoving range looks like.

• The hands that crush you: aces and kings, where you are drawing thin.
• The hand you split with: the other ace-king, a chop that costs nothing.
• The hands you race: queens and sometimes jacks, where you are the 43% side.
• The bluffs: suited wheel aces and the occasional broadway hand, where you are a large favourite.

Add the dead money already sitting in the pot from the open, the 3-bet and the 4-bet, and calling off at 100bb is right against almost everyone, even though each individual pair beats you. Balancing that against the opponents who genuinely only shove aces is most of how to play ace king for a profit.

Playing queens against a 4-bet

From the other chair, the queens are strong enough that folding them is usually the bigger mistake.

Ace-king makes up sixteen combinations. Aces and kings together make up twelve. A 4-betting range of exactly those three hands still leaves your queens above 40% equity, and the dead money more than covers the rest.

The exception is real, though. Against a player whose 4-bets you have seen turn over aces and kings and nothing else, queens are a fold and you should not feel clever about it. Solvers mostly 4-bet queens themselves and rarely fold them to a single raise at 100bb, but a solver is not playing against a nit who has shown you the same two hands for three hours.

When the money goes in after the flop

If the stacks survive preflop, the flop settles the hand almost immediately.

An ace or a king flops. Queens have two outs and a hand that cannot call a large bet. Roughly a third of flops contain one of those cards, and the pair should be looking for a cheap route to showdown, not a war.

A queen flops. You are drawing to running Broadway cards with ace-king. Fold to the first serious aggression and move on.

A low, disconnected flop. Queens are a heavy favourite and should build the pot. Ace-high here is a draw with six outs, not a made hand, and treating it like one costs stacks.

Position decides how cheaply either hand escapes. In position with ace-king you can check back the flop, take a free card and pay one bet to reach the river. Out of position you either bet into a range that never folds a set, or check and face pressure holding six outs. The same asymmetry punishes the queens on an ace-high board, only with two outs instead of six.

The rule for the ace-king side is simple: after the flop, ace-high is a drawing hand. Play it like a flush draw you cannot see, and fold it as readily.

Drilling it until it is automatic

Numbers stick when you generate them yourself. Run A♠K♠ against Q♥Q♦ in a poker equity calculator, then change the king to a heart and watch the three points evaporate.

Do the same for the neighbouring spots, because the JJ versus AK race lands in almost exactly the same place as this one, which tells you the rank of the pair barely matters once it is above your kicker. The complete picture of AK against every pocket pair shows where the curve finally turns and ace-king becomes the favourite.

Guess before you press calculate. The gap between your guess and the answer is the leak, and it closes fast once you have seen it a dozen times.
