Yeah were it not for so many callers PF I would have certainly 3bet larger, I guess I got afraid, which is terrible, backwards thinking. I usually do 3x the original bet when I 3bet PF, this hand was just weird cause there were so many callers and QQ isn't necessarily the top of the list for 3betting...I was never in a situation like this one before.
But for the flop: Isn't a 2/3 pot bet enough to deny odds for a flush draw?
