My reasoning for betting the flop the way I did was that I figured I might get someone with a lesser flush to fold without the Ah, which I was holding. Of course, it didn't work and I called the turn just because there was so much money in the pot.

Was my bet on the flop a bad one, and how could I have played the rest of the hand?
