Ok, so my preflop call of a reraise wasn't that good [img]/images/graemlins/smile.gif[/img] ; I put the villain on a high pair, Aces most likely. I hit a great flop, figured an Ace, 3, 5, 6 would give me the nut straight, so that makes 11 theoretical outs right? Now Villain likely has two of those aces, but I still like my chances. Anyone think my reraise on the flop wasn't the right move? What would you have done?

Several people on the table thought I played incorrectly; the Villain said "you raised on a draw??!!!"
