AJ vs A7s is the matchup every "but I had top pair" cooler is made of: AJ wins 64.9%, A7s wins 27.6%, and 7.4% of boards chop. Live to only its odd card (plus a thin straight or flush), A7s wins about 1 in 4; the 7.4% tie figure is the tell that these hands are tangled on the same rank.
At a final table the raw 68.7% / 31.3% split is only half the story — ICM bends it. As the 31.3% underdog, A7s pays an extra survival premium, so the chip-EV "close enough" call can be a clear ICM fold. The pure equity sets the floor; the payout ladder sets the real price.
The lesson of AJ vs A7s is kicker discipline: A7s is the hand that quietly costs people stacks because it's too strong to fold and too dominated to win. If you hold AJ, get value while you're ahead; if you hold the dominated side, this is the exact spot to find a preflop fold against a tight range.
