AQs flops monster draw

I know I mucked this up, I think I was already shooting my wad...I didn't want to check it because I figured someone had at least a piece of it, maybe even a K, plus I had been c-betting most flops and I thought a check would be suspicious. What amount should I have bet to keep people in?

It's fine. It's a dangerous board and you need to improve to beat a lot of hands that call you here. I'm happy taking down a small pot and moving on.

Standard. If you are chronic c-bettor, playing it weak would be very bad.

Play it for stacks if someone plays back at you. Vnh.

Dude... i'm really not sure what your trying to say. Do you think you have a monster hand? Your draw isn't that monster either. You most likely have just a flush draw (and a straight draw that if hit probably will just give a split pot) if someone plays back at you. Because a raise or a call requires at least two pair, one of those pairs most likely being a Q or a set. You WANT to take down that pot on the flop.

meh...pair plus nut flush draw (one of those outs to the nut of all nuts), plus straight draw, and the opportunity to take a big pot once a heart falls...I figure that's a pretty decent draw. I know I could potentially be behind on the flop...I wanted something like Th9h or AJ to come along...
