Top 2 on a monotone board facing a push. Deal....or No Deal?

[CappyAA]

Ok, no reads, and I probably shouldn't be playing at this point b/c I had just been stacked on 2 separate tables in the past 10 min and I'm tilting. Welcome to Full Tilt NL100!!!

I've been playing at this table for a few orbits. I don't have any meaningful stats on villain other than I've seen him cold-call a number of preflop raises. He seems loose preflop. No notes on his postflop play.

Effective stack - $105

Hero is in MP with A [img]/images/graemlins/spade.gif[/img] K [img]/images/graemlins/spade.gif[/img]

Preflop: UTG calls, Hero raises to $5, CO folds, Villain (Button) calls, SB folds, BB folds, UTG calls

Flop: ($15.00) A [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img]
UTG checks, Hero bets $15.00, Villain raises all in to $100.00, UTG folds, Hero..........

I really didn't know what to do here. I mean his range could be anywhere from AA, KK, 66, QJd, AxQd, etc. What does everyone think here?
