[Event "FIDE Grand Prix 2017"] [Site "Palma, Majorca"] [Date "2017.11.22"] [Round "6"] [White "Tomashevsky, E."] [Black "Radjabov, T."] [Result "1-0"] [ECO "B08"] [Annotator "GM Elshan Moradiabadi"] [PlyCount "115"] [SourceDate "2017.11.23"] [SourceVersionDate "2017.11.23"] {A game between players in the middle of the crosstable could not be so decisive unless one of them (Radjabov in this case) is trying to win GP points in order to earn a spot in the Candidates tournament next year. In what seemed to be a dull encounter, the Russian "professor" (Tomashevsky's nickname based on an online blitz account!) managed to grind his small advantage and convert it into a full point. Now, Radjabov's chances to qualify is substantially reduced unless he manages to pull out a number of wins in the coming rounds!} 1. d4 d6 2. e4 Nf6 3. Nc3 g6 4. Nf3 Bg7 5.
