check-min-raised AGAIN on turn .. what does he have?

[poincaraux]

He hasn't seemed super out of line, but his stats are 51.92/25/2.0 over 52 hands.

On the flop, I think he can do that with a draw pretty often. I've also seen it with air and strange overpairs.

On the turn .. uh .. um .. I'M SO CONFUSED PLEASE HELP ME!! This situation has literally never happened to me before. How often does he have a jack? How often does he have some nutcase overpair? Does he ever have a draw? If this is for value, how can he be so sure that I'm going to bet again?
