Semi-Slav Mamedyarov Wins

Veteran players rated over 2700 rarely lose quickly. Super grandmasters are especially difficult to beat in under 30 moves. Boris Gelfand was born in Minsk, Belarus in 1968. Boris became a grandmaster in 1989. By 1991 he was a World Championship Candidate. Gelfand later emigrated to Israel. He is hard to beat.

Grandmaster Shakhriyar Mamedyarov of Azerbaijan twice won the World Junior Championship. In 2013 Mamedyarov won the World Rapid Chess Championship. In December 2016 he was the 12th highest FIDE rated active player in the world at 2768.

Queens Gambit Semi-Slav Defence 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 c6 5.Bg5 gives Black many options. The main line is the Moscow Variation 5...h6, although the Botvinnik Variation after 5...dxc4 is also interesting and playable. After 5...h6 Black gets the bishop pair and a solid position. White obtains more active central play with extra space and a lead in development.
