Israel's Boris Gelfand took a significant step towards an historic achievement on Sunday, beating defending-champion Viswanathan Anand in Game 7 of the World Chess Championships in Moscow to take a 4-3 lead in the best-of-12 series. After the first six games all ended in draws, Gelfand made the most of playing with white pieces and Anand's under-par play to claim a win and edge closer to becoming just the 16th undisputed world champion since 1886.
