A tough game collision

[ShawnHoo]

I observed the following hand Friday night at Commerce. It took place in a 40/80 game that was unusually tough by SoCal standards. How well/poorly did each player play their hand? I'd be interested to hear how folks would have played differently in the respective situations.

UTG, an extremely solid regular, raises with QQ. Folded around to button, who doesn't play many hands and apparently doesn't recognize UTG as extremely solid, who flat calls with AdQh. SB calls, BB calls with KTo. BB is a young pro who is exceptional at hand-reading.

Flop: QdTdTh

SB checks, BB bets, UTG calls, button calls, SB folds.

Turn: 6h

BB bets, UTG calls, button raises, BB shows his hand to the SB and folds, UTG 3-bets, button calls.

River: blank

UTG bets and is called.
