QQ early, too passive? ($22)

Completely lost the ball on this one. For some unknown reason I was afraid of the flush even when his line doesn't indicate it at all, so I just wanted to keep the pot small. Who would have bet the turn and/or river, how much and why?

I think this is OK, the ace is a terrible card and the Q I guess catches you up with 55,TT and JJ but is still a terrible card for you to get any value from any hand you beat, just check it and shake your fist at the gods

I think you played this fine.

My only question is whether opp check the river with a hand that beats us? I guess Kx might be looking for a cheap showdown given the 3-flush on board. I also agree that opp is unlikely to call with any hand we beat.
