If your opponent blunders a piece, but you don't take it, is it still a blunder? Yes, it is... except now there were two blunders! In IM Rensch's latest Live Session, his superior opening leads to a great middlegame position, but when he fails to take advantage of his opponent's obvious mishap, he must try to convert a small endgame advantage. Does he have enough to win, or does another one bite the dust?
