this hand is worth recapping:
i raise AQs from the BTN pre. @iv4n check-calls with 77. 2-diamond flop, @iv4n checks. of course i bet my nut flush draw + overcards into him. same on turn. he check-calls a pot-sized bet on river diamond.
i wasn't raising with nothing, like you said. after the flop, i was the favorite to win! when you showed weakness, i wanted to steal the pot, knowing i still had many outs on the river. i am amazed you are calling down 3 streets with nothing but an under pair!
Damn. had me right from the get go... dirty limped pots 
I likely wouldn't have stacked off with that turn, I do sometimes bluff those 4 to a flush boards on the river but only if I have no showdown value. You could have gotten more chips out of me though... not many but checking turn would have given me a bit of confidence.. Hard to do when your creaming your pants with the nuttiest of nut hands.
yeah i quickly thought about what you might raise my flop bet with, hoped for a spade, and ran with it.
