100NL, AKo on weird c/r strong board

villain is 14.85/4.85/3.3 over 229 hands. After he insta shoved on the river, i put his range on AA,QQ,99,AQs,AQo,ATs,ATo,AJs,AJo and other Ace rag hands. Wow, i just cant see any hands he c/r with on flop and i soundly beat on the river. Any thoughts?

idk that's a weird play sequence. Minraise, 1/2pot, psb. Most likely he's strong and the small bets at first were him trying to get some money, then on the river he realized "Hey I bet this guy has an ace and he'll call off all his chips." He could also have an A, but I think I fold this. Of course, I'm terrible lately.

he has AT/A9 IMO and i hate calling.
