Flopped nut flush

[Frank Zappy]

PF: I like 3 betting AQs instead of the CC; it's just to big a hand to treat like 98s.

Flop: Never miss an opportunity to raise here. Calling is just wrong.

Turn: See "Flop" note above. Raise! What's the point of calling here?

River: UTG has been playing the second nut flush, I don't think he filled here. If he flopped a set and is betting like this I'd definately make a note that he's either colorblind or overplays sets on monochrome boards where people have obviously made a flush.
