Villain is semi-unknown but seems very fish so far running 27/0 after about 19 hands. I noticed that he wasn't a maniac postflop but wasn't too passive either. With those reads I usually go into the "Oh he can easily raise with an overpair/A9 here then" but I don't know.

In hindsight I do not like my flop bet size. I was hoping to just get a flat call and in my head at the time was "please don't raise". If I bet more on the flop and he raises is it more of a b/f? Enlighten me, BC.
