Live - QQ deepstacked, what am I doing on the turn?

[Bluegrassplayer]

Weirdest hand I've played in awhile. At a casino so I'll reenact it best I can. The opponent here was just recently moved to the table, but seems to be pretty LAG.

FR but only mentioning the stack sizes of the two of us that saw the flop:

CO (Villain) $575

SB (ME) $595

Preflop you are dealt: Q [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/club.gif[/img]

UTG +1 raises to $10

folds to CO who raises to $25

SB (Me) raises to $85

folds to CO who calls.

Flop ($182) ( is: 5 [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img]

I bet $150

CO calls.

Turn ($482): 9 [img]/images/graemlins/spade.gif[/img]

I really have absolutely no idea whats going on here. I feel like if I check I lose the hand automatically, but what am I beating here? The only hand I can think of is K/A of diamonds.
