i think calling is better EV in the long run

good chance for AT to AQ
AK looks very unlikely , since he would probably reraised PF
77 and 55 is quite possible the way he played , that he wants u to pay your stack for holding an Ace

since if u hold Ace u will probably pay all chips
if u hold anything else, u cant call any size of riv bet
