Ace-king (A♠ K♥) wins 64.1% of the time against queen-jack (Q♦ J♣), loses 35.5% and ties 0.4%, all in before the flop. Equity: 64.3% to 35.7%.
Counted exactly over all 1,712,304 boards, not simulated. Equity counts a tie as half a win.
Why AK is the favourite
Two higher cards against two lower ones, no pair: each hand needs to pair, and the higher cards win when both pair or neither does. The lower hand has more straights, which keeps it in the race, but the higher cards are the favourite, close to 2 to 1.
What it means for a call
An all-in call is right when your share of the pot is at least the price. With 35.7% equity, queen-jack needs the pot to offer at least 1.8 to 1 to call against exactly ace-king. In real hands nobody shows their cards: compare your equity against the whole range of hands that would bet this way, in the equity calculator or the preflop odds chart.
Suits change the numbers by a point or two: shared suits take flushes away from one hand. These are the suits shown above.
