Villain is a major fish. 52/0 over ~100 hands, will bet when checked to, likes to try to steal pots, will showdown marginal hands but I haven't seen him play for stacks. I put him on Kx here, but possibly air. AK and I'm getting his stack, weaker K's I'm not sure. How do you like my passive line and what's your play? Plan for the river?
