[Event "European Championship, Plovdiv"] [Site "masterchessopen.com"] [Round "0"] [White "Grigoriants, S."] [Black "Tregubov, P."] [Result "0-1"] [ECO "A04"] [Opening "Reti: 1...c5"] 1.Nf3 c5 2.c4 { This line is known as the Symmetrical English. } 2...Nc6 3.Nc3 e5 4.e3 Nf6 5.d4 cxd4 6.exd4 e4 7.Ne5 ( 7.Ng5 { is also met by } 7...Bb4 { , when } 8.d5 Bxc3+ 9.bxc3 Na5 { is the basic position, offering equal play. } ) 7...Bb4 8.Bd2 { The natural reaction is to block the pin. I saw this move recommended on the Internet and thought nothing more about it until I saw this game. White's assumption is that he won't lose a pawn because of his own threat of 9 Nxe4. After all, surely a top-rated Russian grandmaster wouldn't go wrong on move eight, would he? } ( { Instead, } 8.Be2 { is the established move; for example, } 8...Qa5 9.Nxc6 bxc6 10.O-O O-O 11.Bd2 Re8 { led to equal play in L. Pantsulaia-B.Jobava, Tbilisi 2008. } ) {#R} 0-1
