so one of my buddies posted this hand in the chat today and  , when i saw it , the sizing really upset me , because imo it was really bad to 3bet 3.5x in position being 36bbs effective. obviously , the point when he posted it was "i couldve folded to the 4bet even vs this aggro retard". what do you think about his sizing there?
