Not very many hands on villain yet but he seems to be a passive player on the flop, and turn, but he was pretty active in betting the river. He is limping 1/4 of his hand and raising the other halfish. He has been folding 40% out of the BB and has been calling and 3 betting about 30% each.

I raise it up 4x for value and also he has been limp folding sometimes too so I can win the pot outright.

I lead for value and he calls.

I check because I feel like a lot of the hands he called with are not going to call another one of my bets on the turn so I check planning to give him and opportunity to bluff with his random floats and maybe striaght draws or flush draws?

I get literally tripped up on the river action though! :D

First I have to figure out if he is going to continue bluffing if he as bluffing on the turn. How much is he really bluffing the turn when he bets that small? It looks like some sort of thin value bet or weak bet. Probably not a hand that would continue firing on the river?

He could have actually had a hand on the turn that he was betting for protection or something that he will check back on the river which makes a case for leading the river.

In game, one of the reasons I didn't lead is because I was afraid for some reason villain might have had a stronger King than me and I was afraid on how to handle it if he raises my river donk. I would probably fold right if he shoved the rest in as he is repping 56, K7, K4, K3, 44, 33?

Leading the river is the best play right? And how much should I lead out here?
