Holger Ellers (Germany) v Ognjen Cvitan (Croatia), Biel 1996. This week’s puzzle is a dramatic position where Black (to move) is a bishop and pawn up while White’s pawn is poised to queen and prepare Qg8 mate.
Black need not fear this mate, since he can draw when he likes by perpetual check with Qf2+ and Qf1+. That looks the normal result, but former world junior champion Cvitan found something better. Can you do as well?
