checking and betting in the dark

[SharkBait]

Playing 2/5 NL at Wynn last weekend. Solid Asian guy raises 3x w/ AA in EP I RR 3x on his immediate left. He checks dark and I 1x on K98, He checks dark and I 1x on a 5. He checks dark again and I push for 1.2x. He calls and I show him Kings full. I had been fairly aggressive in the short time I was at the table. Bad result for him but not a bad way to play AA against an aggro opponent.
