I put him on AA-KK, He's at 2 or 3 of my tables and has been playing very tight/solid.

After he folded he said "merry christmas, ihad AA"...i am pretty sure I believe him.

Anyway... After raising 5 preflop, the only hand he has that im even remotely scared of is AKhh. Should i have flat called the flop and hoped he fired the turn?
If i did flat call the flop, I would have lead out with a hard bet if a heart, J, or Q fell....
