Yeh it's probably a fold deep down but calling off is wte
I just felt like it should be a fold like 70%+ and that I know how there are hands sometimes that you just say "i was always going to lose it all there.."
But in a discussion group we have, i did the same thing to someone else the day before with exactly top set (i minraised turn in his pos, then overbet bombed river) and the guys all said
"there aren't many ways to make someone fold a set - but I think you just found one"
Maybe it should be closer than it looked... But having tried to run people down when they min5bt OOP I've noticed - ITS ALWAYS AA.
