But since there is no where else to put it.

Villain is a fish but unknown how he really plays. This is like his 4th or 5th hand at the table I've played every one of those.

I guess I could raise the turn but I think that line looks too strong and can get more value out of his bluffs by calling and I can still value bet the river when it's checked to me.
