Victor Mikhalevski v Bator Samsubu, Canadian Open, Ottawa . White (to move) has an obvious advantage, so the commentary team discussed the most effective way to force resignation. They settled on 1 Bh with the threat  g fxg  Bxg+ Rf  Qxf mate where Black's f rook is pinned so cannot take the queen. However, Black can fight on for a while by 1 Bh Be  Rce1 Kd. The commentators were still arguing when grandmaster Mikhalevski made his move. It was so strong that after it, Black's reply and White's next turn, Black had to resign the now hopeless position. Can you find what the grandmaster saw and the lesser lights missed?
