Counted exactly over all 1,712,304 boards, not simulated. Equity counts a tie as half a win.
Why QQ is the favourite
The pair is between the two cards of ace-jack: one card is higher (three outs to pass the pair), the other is lower and only helps through straights or two pair. With three live outs instead of six, the pair is a clear favourite, about seven times in ten.
What it means for a call
An all-in call is right when your share of the pot is at least the price. With 28.5% equity, ace-jack needs the pot to offer at least 2.5 to 1 to call against exactly pocket queens. 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.
