Why it comes out this way
Both hands hold a queen, and ace-queen also holds the ace — the one card that beats everything king-queen can pair. King-queen needs a king on the board without an ace, or a straight or a flush. The hands split the pot on 1.1% of boards.
Ace-queen wins 73.2% and king-queen wins 25.7%. Suitedness is part of the answer: against king-queen, AQs wins 74.0% and AQo wins 72.9%. The AQ wins figure in the table is the average of both, weighted the way they actually come out of a deck — one suited combination for every three offsuit.
