Congrats to Daniil Dubov on becoming the 2018 World Rapid Champion. He took clear 1st place with 11/15 points and no single loss.

Daniil Dubov

Daniil Dubov won World Rapid Champion tittle while he had missed his grand father, Eduard Dubov, last week. Eduard Dubov was a well-known arbiter and mathematician, tragically passed away in Moscow at the age of 80. Honorary member of FIDE, author of Soviet rating system, Eduard Dubov made a significant contribution to the development of chess in Russia and abroad. Our deepest condolences...
