He played a set of queens semi-bluff. Do opponents could have a flush draw and a straight draw (nuts). And so it happened. He took a chance and lost. He knew what he was doing. Wrong.
I agree, and you have to keep your cool wathever it will happen because sooner or later it will happen. For money it is better later in the tournament .There are spots where your gonna get called no matter what, and you just gotta deal with it. There are really only two roads, you either go slow and fold when it hits or push and hope they get out.
