AA vs A3s mixes a pair with an overlapping overcard, so an out on each side is already in someone's hand. AA wins 86.8%, A3s wins 11.9%, and 1.3% of boards chop. That blocking effect is why AA is a firmer 7.3-to-1 favorite than a straight pair-vs-two-overcards race.
Here's the intuition behind 87.5% to 12.5%: AA wins roughly 7 of every 8 times the chips go in, but the underdog cashing 12.5% of the time is exactly why you can't slow-play and let it draw for free.
How you play AA vs A3s depends on which side you hold. With AA you're not crushing, so keep the pot controllable and take the 86.8% edge to showdown when you can; with A3s, your equity is enough to continue with initiative but thin enough that bloating the pot out of position is a trap.
