25NL - JKs river screws my nuts

[VLV]

Villain is 73/18/3 over a about 200 hands. Although the stats are pretty loose he's pretty passive post flop, not extremely, just not as loose as you would expect from someone like this.

I doubt he has AK here but I feel that if I raise I'm most likely splitting. Not sure though.

I feal pretty ok just pushing here you way ahead of his range and he prob looks you up with alot of 2 pair hands.

I make a valueraise here might call with an 8 or weaker hands.
Can't see him having AK here too at worst it's a split at best you get good value.
