I've played with this villain quite often. I have about 1500 hands with him, a few at 2nl, most at 5nl, and some at 10nl. Overall he's about 23/7/2.5 (and hasn't been far from that at any level) and he seems to play back at my aggressiveness a bit more often than most players I've faced. Is this a check/fold on the turn, or do I bet again, which would really need to be an all-in?
