Villain is a multi-tabling regular. He's 27/4/4 over ~1000 hands. He used to raise my c-bets a lot. I started c-betting him less and 3-betting him quite a bit when he did raise. I don't think he is making a move on me this time. That's my thinking on his turn play. My bet sizing sucks. I should be betting out like I would with my standard c-bet but I'm donkishly trying to act weak and then not sure what to think when he shows strength. What's a good line here?
