My opponent is a loose raiser (and a loose limper too) and sometimes go too far with his hands postflop, but he dont seem crazy.

So what should I do on the river and do you like my line in the hand ?

I think Either pushing the flop or CRaising all in on the turn is stadard. Don't second guess yourself.

Maybe Im too passive in a spot like that but I tought that I could only get called by a better hand if I check-raised the turn all-in with the stack size.
