25NL - Is this a positive EV call?

[AAmucked]

Villain is xXStealth on FTP. Seems solid for this level, but he has some unorthodox plays, not sure if this can be considered good or bad.

Villain open-limps in the CO, SB completes and I raise 10 [img]/images/graemlins/diamond.gif[/img] 10 [img]/images/graemlins/spade.gif[/img] to 6x the BB. Villain insta calls and SB folds.

Flop comes 8 [img]/images/graemlins/club.gif[/img] 4 [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/club.gif[/img]. I bet 3/4 pot, villain instacalls.

This is a draw a lot of the time as is common knowledge and I immediately put that into his range.

Turn is the J [img]/images/graemlins/heart.gif[/img]. I check, he bets 3/4 pot pretty quickly. I call.

River comes K [img]/images/graemlins/diamond.gif[/img]. I check, villain bets 2/3 of the pot. Hero..?

If I read villain correctly for a draw on the flop, is calling here on the river a profitable play given that two overs hit? Villain seems solid for a 25NL so I put his preflop limp/call range as two over 10/SCs/pps over 5s.

If you think it's a draw, why don't you bet the turn?

Because a FD hand with that would limp/call pre could easily contain a J? That was my thought process at the time but I guess not betting here is pretty weak.
