When a pair meets two bigger cards you get a flip, and 55 vs AT is exactly that: 55 wins 52.6%, AT wins 47.0%, and 0.5% of boards chop. The overcards lean on six live outs — either Ace or Ten pairs to take the lead — which is why the unpaired side converts about 47.0%, the math behind every "I have to gamble" all-in in a tournament.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, 55 carries 52.8% equity and AT 47.2%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so AT is comfortably priced in to get it all-in here.
How you play 55 vs AT depends on which side you hold. With 55 you're not crushing, so keep the pot controllable and take the 52.6% edge to showdown when you can; with AT, your equity is enough to continue with initiative but thin enough that bloating the pot out of position is a trap.
