Inspired defence

In the opening rounds of the Belgrade Grand Prix there were two splendid instances of defensive queen sacrifices. These remarkable efforts set Jon Speelman thinking about defence in general. He thus turned to one of his favourite books, The Middlegame by Max Euwe and Hans Kramer, and cherry-picked a couple of games from the chapters on Steinitz and Lasker. | Pictured: Emanuel Lasker / Collection of the World Chess Hall of Fame
