5/10 6max Bottom Set vs a LAG

[Seether]

CO in this hand is a total LAG and feeding the game. My preflop 3 bet was an attempt to isolate him. I am specifically curious about my river play but comments on all streets are appreciated.

I'd raise the river and call a 3-bet.

I'd raise and call a 3-bet every time.

Like it all except the river, do what those guys said.

Hey just want to say that imo this is one of those hands which doesn't need to be here...you know you made boo-boo, it's ok no need to ask here for clarification, self teaching is very goood...
