What the flop does to it
When no J comes on the flop (87.8% of flops), AKo has 80.4% equity going to the turn. When one does, AKo drops to 28.6%.
AJo shares a card with AKo, so pairing that card doesn't help: it needs its other card to come. Domination like this is why calling with weaker hands of the same kind costs so much.
