Both these hands are against the same villian. I hate saying i made a crying call, but In hand one can I find a fold. Im not sure if he plays qq, jj in the same way.

UTG had A[img]/images/graemlins/spade.gif[/img] A[img]/images/graemlins/club.gif[/img] (two pair, Aces and Sixes) and WON (+$81.80)
Hero had K[img]/images/graemlins/diamond.gif[/img] K[img]/images/graemlins/club.gif[/img] (two pair, Kings and Sixes) and LOST (-$84.05)

In the second hand, when he 4-bets me my thought process was something like "surely he cannot have Aces again, vs my kings - same opponent same setup? Should I be folding here?
