AA vs A5s mixes a pair with an overlapping overcard, so an out on each side is already in someone's hand. AA wins 86.1%, A5s wins 12.7%, and 1.3% of boards chop. That blocking effect is why AA is a firmer 6.8-to-1 favorite than a straight pair-vs-two-overcards race.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, AA carries 86.7% equity and A5s 13.3%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so A5s needs real fold equity, not just its raw share, to justify stacking off.
How you play AA vs A5s depends on which side you hold. With AA you're not crushing, so keep the pot controllable and take the 86.1% edge to showdown when you can; with A5s, your equity is enough to continue with initiative but thin enough that bloating the pot out of position is a trap.
