AQo vs 66

When AQo and 66 get all in before the flop, AQo wins 45.5% of the time and 66 takes 54.5%. Broken down, AQo wins outright 45.3%, chops 0.4% and loses 54.4% — a margin of -9.1 points. Pair against two overcards — the classic coinflip, with the pair a shade ahead.

The same matchup shifts depending on how the suits overlap. With no shared suit the number is 44.9% (for example As Qh against 6d 6c); with both suits shared it is 45.7% (As Qh against 6s 6h). That is a spread of 0.83 points across the 72 distinct card combinations, and it comes almost entirely from whether the two hands are fighting over the same flush.

Add a third player holding a random hand and the split becomes AQo 38.5%, 66 39.8%, random 21.7%. AQo gives up 6.9 points and 66 gives up 14.8, so the underdog loses more than the favourite does. Extra players always eat into the leader's share faster than into anyone else's.

Taken on their own, AQo is worth 64.4% against a random hand (rank 14 of 169) and 66 is worth 63.3% (rank 17). The gap between them in the ranking is only 1.1 points, yet head to head the gap is 9.1 points — a reminder that a ranking table and a direct matchup are two different questions.

Framed as a run of one hundred identical all-ins, AQo scoops roughly 45 pots, splits about one, and loses the remaining 54. Against eight random opponents rather than this one specific hand, AQo would be down to 17.5% and 66 to 13.7%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From 66's side, 54.5% is the break-even point for calling an all-in at 0.83:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 54.6% of the pot you are playing for. AQo holds the other 45.5% of that same pot.

Two caveats keep this figure honest. First, it is showdown equity across all 72 card combinations with five board cards still to come — there is no fold equity in it, so the value of shoving in practice is usually higher than the raw percentage suggests. Second, it assumes 66 really does hold exactly 66; against the wider range a player would actually get all in with, AQo's 45.5% moves. Use the individual pages for AQo and 66 to see how each of them fares against all 168 other holdings before treating this single pairing as the whole picture.

When the three flop cards are out, AQo is ahead 31.0% of the time and 66 69.0%, and the two hands are never level on the flop. "Ahead" means the better best-five-card hand from the cards showing plus the two hole cards; draws are not counted.

When AQo leads on the flop, 66 comes back on the turn and river 10.5% of the time. When 66 leads on the flop, AQo turns it around 25.4% of the time. The hand in front holds on to win 78.8% of the time from the flop and 88.1% from the turn (level spots left out).

With the turn out, AQo leads 38.6% and 66 61.4%. Counted exhaustively, AQo finishes with 45.36% equity (the 45.5% at the top of the page is a 200,000-hand simulation).
