Caruana beats Mamedyarov and catches up with Gelfand

Round 4 has been over in Baku where the 1st stage of the FIDE Grand Prix 2014/15 is taking place. Fabiano Caruana, ranked 2 in the world, scored a convincing victory over Shakhriyar Mamedyarov and caught up with the tournament leader Boris Gelfand.

CARUANA - MAMEDYAROV
The Slav Defence
1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.e3 Bg4 5.Nc3 e6 6.Qb3 Qb6 7.Nh4 Bh5 8.h3 g5!? This sharp and fashionable variation had already taken place in the game between the same opponents in Vugar Gashimov Memorial (April 2014). 9.Nf3 h6 10.c5. The aforementioned game went into a sharp endgame after 10.Ne5 Nfd7 11.Nd3 Bg6 12. h4 Rg8 13. hxg5 hxg5 14. Bd2 dxc4 15. Qxc4 Qa6 16. Nc1 Qxc4 17. Bxc4 Nb6 18.Be2, which Caruana managed to win in 56 moves (Caruana - Mamedyarov, Shamkir 2014). 10...Qc7 11.Bd3 Creating a positional threat of g2-g4. 11...Rg8?! The crucial line seems to be 11...Bxf3! 12.gxf3 followed by 12...b6 or 12...Nbd7. 12.Qc2 Nbd7 13.b4!

White has better prospects. 13...Be7 The games Ftacnik - Ruck (Germany 2009) and Eljanov - Sandipan (Plovidv 2010) saw 13...Bg6. 14.Bb2 g4?! 14...Bg6 was preferrable. 15.hxg4 Rxg4 16.Kf1! Now White is seriously better because Black's activity at the king side doesn't provide sufficient compensation for his weaknesses. 16...0–0–0

17.Ne2 More reliable than 17.b5 Rdg8 where White would have to play 18.Ne1. 17...Rdg8 18.Nf4! Rxf4. The exchange sacrifice is more or less forced. 19.exf4 Bxf3 (19...Qxf4 20.Rh4) 20.gxf3 Qxf4 21.Ke2! Rg2?! 21...h5!? was more persistent.

22.Qc1! Qg3 23.Qf1! The seemingly active Black's heavy pieces are suddenly trapped. The point is that, for example, 23...Qg8 can be met by 24.Qxg2! Qxg2 25.Rag1 with decisive advantage for White in the endgame. 23...Ng4!? 24.fxg4 Qxg4+ 25.Kd2 Qf4+ 26.Ke2 Qg4+ 27.Ke1 Ne5 28.Be2! Caruana has to be precise. 28.dxe5? Qxb4+ could have spoiled everything. 28...Qe4 29.Kd1 (the alternative is 29.Rh3) 29...Bg5 30.dxe5 Qxb4

White still has to be very accurate in spite of his huge material advantage. 31.Kc2 (the only suitable defence from the mate on d2) 31...Qxc5+ 32.Kb1! Rxf2 33.Qd1! Not 33.Qe1? Qe3! with sudden complications. 33...Qe3 34.Re1 Killing the opponent's hope for a blunder like 34.Bd3?? Rd2. Mamedyarov resigned. Caruana played the game with maximum precision. 1–0 (Annotated by GMs M.Golubev and A.Deviatkin).

All the drawn games of round 4 were quite persistent. Peter Svidler did something wrong in the opening against Rustam Kasimdzhanov and was on the verge of losing. Hikaru Nakamura outplayed Alexander Grischuk gradually in the King's Indian Defence and was seriously better just 2 moves before the peace treaty (this accounts for his inaccurate 46th move). Boris Gelfand as Black went for the Sveshnikov variation against Leinier Dominguez, sacrificed a pawn and took the initiative, but at some point decided to be satisfied with the threefold repetition. Evgeny Tomashevsky missed 21.Bd6! which could create problems for his opponent Sergey Karjakin. Teimour Radjabov held a slightly worse position against Dmitry Andreikin.

ANDREIKIN - RADJABOV

There are different ways to improve on 28.Qe2 chosen by White. Let us mention an unusual one: 28.Qxd5 exd5 29.Rd1!? White doesn't hurry to take the e7-pawn, provoking 29...e6 to attack the b7-pawn by 30.Rb1.

After 4 rounds Caruana and Gelfand are in the lead with 3 points each, Svidler and Nakamura are half a point behind. October 6 is the first day-off in the tournament.
