Tough call or Insta call?

[DanK]

Heres a hand I played today heads yesterday, very first hand with this guy who I have no read on, but have played with before and all I remeber is that I dont remeber anything about him, so hes not a total moron or anything. Blinds 25/50, we both have 5k

I got 9hTd and raise on the button to 125, he calls. Flop is 9c Tc Ad. He checks, I bet 200 he calls. (pot=650) Turn is 5h, he checks, I bet 400, he makes it 1300, I call. (pot=3250). River is a 3. He bets all in for 3400.

So in retrospect I should just push the turn I think, but can I find a fold on the river. I think not as Im getting 2-1 here but it sure looks like Im beat, and If he missed his clubs, or has AcXc it would be a very unusual line.
