qq utg full tilt 500k

[THEOSU]

i have been by far the most active player at the table, which started with 3 players sitting out. i've shown down quality hands, but gotten horribly unlucky. the big hit came in an incredible hand with KK in LP, where the big blind called my pfr, then check/called every street as the board came 55663. he had 68. yeah. oh, and i also lost to a chased gutty, paying off with two pair.


blinds 15/30
stacks:

bb: 4090. he was sitting out, but busted a shorty with kk vs ak on his "first hand"
me (utg) 2280
CO: 3200. nothing of note.


i open Q[img]/images/graemlins/diamond.gif[/img]Q[img]/images/graemlins/spade.gif[/img] utg to 80, CO raises to 285, BB calls, I call.

Flop: 9[img]/images/graemlins/club.gif[/img]T[img]/images/graemlins/diamond.gif[/img]6[img]/images/graemlins/heart.gif[/img] (pot 870)
BB checks, I check, CO bets 540, BB folds, I fold.


comments on both flop and preflop are welcome.
