London Blitz

Britain’s leading grandmaster, Michael Adams, started well in the London Classic, with a beautiful win against the rising star Fabiano Caruana. After that, Adams ran out of steam, finishing in next to last place. Fortunately he made up for this with an excellent performance in the Blitz section, where he tied for first place and won the trophy on tie-break. Scores out of ten were: Adams, Nakamura and Kramnik 6; Giri 5; Anand 3½; Caruana 3.

As the great teacher and world champion Wilhelm Steinitz taught in the 19th century, it often pays to delay castling. If you know where your opponent’s king will be domiciled, it is possible to select castling on the opposite wing and then launch a regicidal blitzkrieg. Less common is for both sides to castle on the queenside and witness one player launch a devastating attack against his opposite number on the same flank.
