The British Chess Magazine Or 10…a6 11 a3 c5 (if 11…×b2 then 12 b1 traps the queen) 12 ×f7+ (of course the hidden attack on the black queen is a theme in this line) 12…×f7 13 ×c5 ×c5 14 f3 f5 15 e5+ f8 16 d4 c8 17 ×f5 g×f5 18 c2 d8 19 ×c5 d1+ 20 e2 ×h1 21 c4 1–0 M Dziuba–A Petriso, Eforie Nord, 2010. 11 a3 a5 12 b4 a6 13 c7 ×a3 Black is able to grab some material, but it won’t be enough to compensate for the rook. 14 ×a8 c6 15 e2 g4 If you get this far then it is useful to know the winning line after 15…e5. For instance: 16 g3 ×b4 (16…g4 17 c7 ×b4 18 f3 with a clear advantage) 17 c7 d8 18 b3 d2 19 f3 (19 ×f7+! h8 20 e6 also wins easily) 19…a5 20 ×f7+ f8 21 a2 c6 22 e6+ ×e6 23 ×d2 ×d2 24 ×e6 1–0 A Aleksandrov–T Nedev, Rethymnon, 2003. 16 c7 e4 17 f3 d8 Black has active play, which might be good enough for a quick game on the Internet, but when you have plenty of time to ponder what to do then giving back some material is a perfect plan. 18 d5 e6 19 f×e4 e×d5 20 e×d5 e5 21 ×e5 ×e5 22 b3 1–0  8 c×d5 ×c3 9 d2 ×a2 10 ×c3!? The modern reply, offering the exchange in return for a strong attack. This unusual move is not even mentioned in the Grünfeld books from ten years ago, so you might well catch out a few players. 10 b×c3 has been known as the solid reply for some time and featured in the celebrated game TV Petrosian–RJ Fischer, Buenos Aires, 1971; now play might continue: 10…a5 (after 10…×d2+ the ending favours White upon 11 ×d2 d7 12 b5 0–0 13 ×d7 ×d7 14 e4, with the superior chances) 11 c4 d7 12 f3 ×c5 13 e5 ×e5 14 ×e5 f6 15 f3 0–0 16 0–0 g7 17 fe1, with equal opportunities in the game E Levin–S Klimov, St Petersburg, 2012. 10…0–0 The critical line has to be the immediate 10… ×c3, but few people are willing to take the risk and the practical results are in White’s favour. In the top-level rapid game Wang Yue–M Carlsen, Leon, 2009, play continued: 11 ×c3 f6 (11… a1+ 12 d2 f6 13 f3 0–0 14 h6 f7 15 g1 threatening to move the white-squared bishop with a discovered attack on the black queen favours White) 12 f3 d7 13 e2 ×d5 14 0–0 c6 (the short-term problem is that the black king is stuck in the centre as 14…0–0? allows 15 c4) 15 b4 a5 16 b5 b4 17 d1 e4 18 e1 d5 19 d2 e6 20 c2 0–0 21 d6 fd8 22 d4 h4 23 g3 with the advantage. 11 c4 ×c3!? Naturally Black has one or two alternatives to a knockout game in 22 moves, so let’s take a look at a couple of grandmasters handling the opening. G R Leitao O A Fier Brazil Championship, 2011 Grünfeld D82 553 [Gary Lane] 1 d4 f6 2 c4 g6 3 c3 d5 4 f4 g7 5 e3 c5 6 d×c5 a5 7 c1 e4 The triple attack on the queen’s knight gives White cause for concern, but prior knowledge of the move means there is nothing to worry about. Fier just cannot resist the lure of the exchange and aims to resist the forthcoming attack and use the extra material to win in the long term. The alternative 11…a1+ has gone out of fashion since the game B Gulko–D Eckert, Saint Louis, 2009, which continued 12 c1 ×b2 13 f3 d7 14 e2 a3?! (maybe 14…a5 should be considered) 15 d4 ×d4 16 e×d4 f6 17 f3 d8 18 0–0 ×d5? Black adds a pawn to his collection but overlooks the possibility of his queen being trapped: 19 ×d5 ×d5 20 a1 b3 21 fb1 1–0 12 ×c3 a1+ 13 e2 f6 14 h4 a6 Black keeps the queen on a1 to restrict the king’s knight, but naturally must try to catch
