Pin It

(12) Grishuk,A (2761) - Nakamura,H (2775) [B76]
7th Tal Memorial (8), 17.06.2012

1.e4 c5 Sicilian Defence 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 A Dragon Variation. Black fianchettoes his Bishop on the h8-a1 diagonlal. It is one of the sharpest variations of the sicilian defence. The term dragon was first coined by Russian chess master Fyodor Dus-Chetimirsky. Who noted the resemblace of Black's king side pawn structure to the constellation 'Draco'. [5...a6 Sicilian Najdorf Variation.] 6.Be3

   Yugoslav attack that gives equal opportunities to both sides. 6...Bg7 [6...Ng4? 7.Bb5+ Bd7 8.Qxg4 Black will lose a piece since the Bishop on the d7-square is pinned.] 7.f3 It is to defend the e4 pawn and at the same time preventing the Black Knight to swing to the g4-square. Ng4 will hit the White's dark square Bishop on e3.  7...Nc6 8.Qd2 0–0 9.g4 This is as good as 0–0–0 and Bc4. 9...Nxd4 [9...Be6 Is an important alternative here. 10.Nxe6 fxe6 11.0–0–0 Ne5 12.Be2 Qc8 (12...Qa5 13.g5 Nh5 14.f4 Nf7 15.Bc4 Rac8 16.Bxe6 Rxc3 17.f5 Rc5 18.Bxc5 Qxc5 19.Rhf1 Kh8 20.fxg6 Qe5 21.Qb4 Qxe6 22.Rxf7 hxg6 0–1 Mastrovasilis,D (2631)-Kanter,E (2394)/Plovdiv BUL 2012) 13.h4 Nfd7 14.f4 Nc4 15.Bxc4 Qxc4 16.e5 Nb6 17.h5 dxe5 18.hxg6 hxg6 19.Qh2 Rxf4 20.Bxf4 1–0 Nakamura,H (2775)-Robson,R (2614)/Saint Louis USA 2012] 10.Bxd4
