200NL 2Pair vs Below Avg Player

[viper930]

Villain in this hand looks pretty horrible, checking in at 35/4/2. Havent seen him pummel the pot like he does on the river. Standard river play is a fold at FR, but I had a ton of trouble putting him on a hand. Discussion on all streets welcome.

I'll bet this flop sometimes and check through it other times looking to get 1 street later or pick off a turn or river bluff. Anyways, bet it this time and hit a nice turn.

Turn bet and call of the minraise are pretty standard imo, but the river bet is hella confusing. Could he be overvaluing an AK type hand here / betting in desperation? Could he have hit an A4 kind of hand?
