50NL: AA getting check min raised on a scary board

[Imrahil]

Villain is 37/8/1.5 over like 40 hands. I had just been raising PF the last two hands both with AK but no one saw what I had.

One hand I raised and villain called me PF and check min-raised an A high flop and I called and we checked it down and his AQ was good.
