His minraise preflop and his turn shove all point towards him being terrible.
He probably never has a boat/quads.

We need 45% to call.

Board: As Ks 9s Ah
Dead:

equity win tie pots won pots tied
Hand 0: 45.105% 45.10% 00.00% 774 0.00 { 4s3s }
Hand 1: 54.895% 54.90% 00.00% 942 0.00 { AQs-ATs, QsJs, QsTs, Qs8s, Qs7s, JsTs, Js8s, Js7s, Ts8s, Ts7s, 8s7s, 8s6s, 8s5s, 7s6s, 7s5s, 6s5s, AQo-ATo }

So we have to call if he does this with AT+.

I think he shows up with more Ax hands than just AT+. However, he probably shows up with a boat once in a while too...I've seen some really stupid stuff in these spots.

You're never making too big of a mistake either way though.
