I play low and middle pairs all the time. Sometimes I will call a re-raise. Every pocket pair has a 20% chance to hit. In a turbo, that is good odds
to me. Your opponent was tilted because his AA got cracked. It amazes me how many people think AA will win. In reality, if you shove AA preflop every time, it will only win 3 out of 10 times if it goes to a showdown. However, it usually wins more than that because of the fold equity it carries. Many times AA wins because everybody else folded.
I would use his tilt to my advantage. Say, well I guess it was a good play because my stack grew. Let em tilt and take the rest of the stack.
