Freestyle
Magnus Carlsen’s run of nine straight wins at the Grenke Freestyle Open was, even by his own standards, extraordinary. The world no. 1 is a zealous advocate for freestyle chess, in which the pieces on the first rank are placed in one of 960 possible configurations at the start of the game. The format has been tested in a series of elite events, but the Grenke Open – held in Karlsruhe over the Easter weekend – was one of very few freestyle events open to players of all levels. Based on the standard of Carlsen’s opposition (which included seven grandmasters), he would have expected to score 7/9 in normal chess (perhaps five wins and four draws). But the uncharted format makes it hard to compare his 9/9 score with historical precedents.
