IMO, the only really bad thing that Greg's opponent did was make that size turn raise. If he's going to call Greg's re-raise, he's better off pushing there. In fact, he may well move Greg off of KK with a push there, depending on Greg's read. The guy made an incorrect read based on Greg's flop bet that Greg was weak. Had Greg actually had something weaker and had folded on the turn, would there be this uproar about this hand? I doubt it.
