I wish I played with people that thought BTN's range after flat calling a 1/3 pot sized bet on the flop on a K73 board was 77 and 33.
So HustlerLA, I guess you were bluffing with some weak hand like 78 or a mid pair? I mean sure if the flop bet was bigger then it would be completely ridiculous to think you could ever be bluffing here but with such good odds on the flop, you could call to either hit your hand or make a bluff at the pot if there's weakness on the turn.
Also, yes it is pretty bad to be calling with AA on the turn if your BB, but not everyone plays flawlessly and they just convince themselves with AA that neither BB or BTN has a king. However, it's also hard to see what he's c/cing with on the turn that beats us.
Oh another thing - can I ask why your (oldjude) calling pre with KQs here when you flop almost the nuts with your hand and yet you don't think it's profitable to be getting the money in?
