weird postflop situation after some nifty preflop moves

[DJ Sensei]

5 handed 10-20.
BB and UTG are both aggressive regulars, and both know me as being one as well. Other reads they may have on me, I dont know.

UTG has $2400, BB has $3900, I have $3200 or so.

UTG opens to $80, I call in the SB with QQ, BB squeezes to $320. UTG calls, I reraise to $860. BB folds, UTG calls again.

Flop comes K 7 2 rainbow (suits are pretty much irrelevant at this point, I think).

Whats my play? The pot is now about $2000, and he has about $1500 behind.

Thoughts on preflop are also welcome, if you can figure out the action [img]/images/graemlins/tongue.gif[/img]. Also, the actions you'd take in response to different outcomes (like BB shoving or BB folding and UTG shoving)
