[5NL] AQo...TPTK facing river shove...villain's range???

Villain is 27/12/15 over 89 hands.

Only real notes on villain is that I had seen him 3bet AKs and 4bet AQo.

Why has villain gone all-in here? When he overcalls in BB and then donks the flop I thought he may have had a FD or a weak Qx, Q8-QJ something like that.

He then puts a sizeable bet in on the turn, I don't give villain credit for a 7x hand like 90% of the time, I think on occasion he has A7 but would he lead out with middle pair on the flop? May possibly still have a FD.

I think around this time I thought he may have called in BB with KQ not wanting to bloat a pot OOP in case both players called. Either way, I was still pretty sure I was ahead of villain's range here.

He shoves the river. A brick. No draws come in, I highly doubt the 8 has helped his hand. Is this a busted FD? Does he think he is value betting a a worse Q?

Thoughts?

You only have a psb left tho right? Pokerstove time mmmmmm ranges
In game
I prolly call who knows if im right.

fold

Not folding vs spazzy type of fish who 4-bets AQ. Usually means he can be more depolarised than you think in other spots and overplay stuff. Not folding to a range of better that contains only boats and 7x when he donks flop and likely has non passive fish tendencies.

i'm snapping him off here i think. he can have tripled some FD's or worse K's and it wouldnt take many combos of worse hands to make this river a call (if my maths is close-ish)

nh cobra, did you muck, call?

stubborn fish could have almost anything here. In play, i honestly can't say what i'd do here.
