New to the table and villain is largely unknown. Before anyone says raise more PF, 4x usually gets the job done to isolate. For some reason lunch today was looser than normal.
My thought process: Is this a WA/WB situation? Seems like it to me, so I don't want to raise and scare off 2nd best hands. I also want to get full value from bluffers. Is river bet enough?
