AK vs A7s is the matchup every "but I had top pair" cooler is made of: AK wins 67.5%, A7s wins 28.0%, and 4.5% of boards chop. Live to only its odd card (plus a thin straight or flush), A7s wins about 1 in 4; the 4.5% tie figure is the tell that these hands are tangled on the same rank.
Translate that into a decision and it's simple pot-odds math: counting split pots as half, AK carries 69.7% equity and A7s 30.3%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so A7s needs real fold equity, not just its raw share, to justify stacking off.
Domination is where preflop hand-reading pays off. With AK you want stacks in; with A7s you want out, because three outs and a prayer is not a stack-off — recognizing that you're crushed against a strong range is worth more than any postflop move.
