I raise 2.5x AThd from CO 38bb effective , very laggy bb calls. I had played with him quite a bit from the day before and he was quite aggressive and defended his bb wide. Flop QJ4hhh, bb chk I bet half pot he cr to about 3x my bet. I decide to jam. Is this even a slightly plausible play, or just spew? Maybe a call is better here but I end up folding a lot of turns I think.
