WEAK TIGHT LAYDOWN?????

[bigjoet]

loose passive (but not terrible) limped UTG.. hero raised on button with AdQs... BB (good TAG) called...
pot: $60

flop: Ks Td Xs, basically 2 flush... i bet on button, everyone calls
pot: $90

turn: Xs, gives me draw to 2nd nut flush with the Q, i check through
pot: $90

river: Jd gives me broadway, BB bets, UTG raised, i thought for a long time and folded... BB folded too..

pot: $150, hero needed $40 to call $150.

what would you do if you rivered set? the difference being UTG might've had Q9... My plan was to raise if BB bet and UTG just called because I know BB would bet on this dangerous board if he had the flush and UTG was more likely to be tricky and check raise...

the more I thought about it, the more I think i should've called because UTG could've had JT (bottom 2), Q9 than a flush..
