Tata Steel Challengers: Vidit has the edge

by Macauley Peterson
1/27/2018 – Korobov and Vidit have been the cream of the crop in the Tata Steel Chess Challengers tournament, and they have scarcely given their peers a chance to challenge the lead. We take a closer look at these two contenders with games annotated by GMs Mikhail Golobev and Daniel Fernandez. | Photos: Alina l'Ami TataSteelChess.com

Who will be the 2019 Masters qualifier?

Tata Steel Chess is a marathon, not a sprint, and it's a bit unusual to have the lead change hands so seldom. This year two players have maintained their grip on the top spots since round three: Vidit Gujrathi and Anton Korobov.

The pair both had very strong starts, with 3½ from their first four games, and have essentially remained neck and neck ever since. Vidit is undefeated, and Korobov just dropped a single point to Bassem Amin (annotated below), but his four game winning streak from rounds three to six made up for it.

However, in Saturday's round twelve, Vidit won with black while Korobov drew with white, so the latter will be looking for a win in the final round, since Vidit will have white with a half point lead.

Let's take a closer look at the two dominant players.

Vidit Gujrathi

Twenty-three years old, Vidit was born in Nashik, India in the western region of Maharashtra. Ten years ago he became the first Indian player to win the World Under-14 Championship in Vietnam. He earned the Grandmaster title in 2013, and became the fourth Indian player to cross the 2700 Elo mark in September, 2017. He told ChessBase India that he was "relieved" after being in the high 2600s all year.

In Wijk aan Zee, Vidit is making his first appearance, but he came in as the top seed, with high expectations.

Anton Korobov

Korobov is a former 2700 player (peak rating of 2723 in 2014), and two-time Ukrainian Champion. He has won the prestigious Aeroflot Open (2012), and twice the Poikovsky Karpov round-robin tournament (2015 and 2016). His big splash on the international stage came in the 2013 World Cup in Tromso, Norway, where he advanced all the way to the fifth round, beating Hikaru Nakamura, and only losing to the eventual winner, Vladimir Kramnik.

"I'm quite an experienced chess player. Maybe I can be called a veteran."

Korobov shows his sense of humor in round six, when he said that he can't be considered in shape because he is "too fat and too old." His performance rating in the Challengers after six rounds was a staggering 3001, before slowing down the second half.

"I am bery cold blooded. I can wait."

But his momentum was stopped in round eight, when he lost to another Wijk debutant, Bassem Amin.

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 0-0 6.Bg5 c5 7.d5 h6 8.Be3 e6 9.Qd2 exd5 10.cxd5 These extremely complex positions formally belong to the Modern Benoni but are more important for the King's Indian (where Black's plan ...c5 is considered nowadays to be the most principled answer to Samisch System) and they more often arise, as in the featured game, through the King's Indian move order. a6 Other important options are ...Re8 and ...h5. 11.a4 11.Bxh6 is answered by Nxe4! followed by ...Qh4+ 11...h5 Now the fight intersects also with lines where White plays Be3 (instead of Bg5, Be3) while Black, respectively, plays ...h7-h5 in one move (instead of ...h6, ...h5) . Such nuances do not make the opening preparation easier but players have to know them. Note that Kasparov in his games preferred 11...Re8 12.Nge2 less common is 12.Be2!? 12...Nbd7 While an immediate 11...Nbd7?! allows 12.Nh3! 12.Nge2 Deviations for White include 12.a5!? and 12. Bh6!?. Nbd7! 13.Nc1 White has to rearrange his minor pieces. Another quite often played move is 13.Nd1 , planning Nec3 and Nf2. One more option is 13.Nf4 13...Ne5 14.Be2 Nh7 Again Black had a choice, between this move and 14...Re8, 14...h4. 15.h3 Still not new, but at least little explored. White makes sure that, after the possible further f4, the g4 square will not be available for the black knight. Still, White is not really planning to play f4 on the next move (for example, after ...Re8), because his e4 pawn will become vulnerable after the retreat ...Nd7. f5!? 16.f4 But now it's a different story. Or, at least, Korobov so decided. Nf7 17.exf5 Previously, 17.Nd3!? Re8 18.Nf2 had been seen in practice. 17...gxf5?! After 17...Bxf5! Amin possibly disliked 18.g4 , otherwise it's hard to understand his decision. But Black is apparently doing very well because White is underdeveloped: Bd7 and, for example, 19.Nd3 Qe7 20.0-0-0? just loses a piece: Rae8 21.Bf2 Bxc3-+ . While after the game move White is at least somewhat better. 18.0-0 Nf6 19.Bf2 Bd7 20.a5 Bb5?! Black could have tried 20...Nh8 21.Bh4 Ng6 22.Bg5 White can also accept the pawn sacrifice, 22.Bxf6!? Qxf6 23.Bxh5 22...h4 21.Re1 Re8 22.Qc2 Qd7 23.Bf3 Rxe1+ 24.Bxe1 Re8 25.N1e2 Ng4!? In a worse for him position Black is trying to complicate matters. 26.Nxb5!? axb5 Worthy of attention was 26...Ne3!? 27.Bc3!? Nfh6?! Again 27...Ne3 could have been a better chance. 28.Ng3! Bxc3 29.Qxc3 b4 30.Qd2 h4 31.hxg4? After Black's principally wrong decision on the 17th move Korobov gradually outplayed his opponent, but now White goes astray, underestimating dangers for his king, Correct was a calm 31.Nf1! and if Nf6 32.Qf2 , winning the h4 pawn. 31...hxg3 32.g5 Qg7! 33.Bh5? White still could have achieved a draw with precise play: 33.Kf1! (planning Re1, which could not have been played immediately because of 33...Qd4+!!) Ng4 34.Bxg4 fxg4 35.Re1! Rf8! 36.Qe3 Qf7!? 37.Qe6! Qxe6 38.dxe6 Rxf4+ 39.Ke2 Kf8 40.Ke3! Rf5 or 40...Rf2 41.Kd3! Ke7 and now 42.Re4 or 42.Kc4 41.Rh1! planning Rh7 or Kg7 42.Rd1! and after d5 another pawn can be attacked: 43.Rc1 33...Nf7! The g3 pawn is like a splinter in White's position. Black's main threat now is ...Qh8! and White should do something about this... 34.Qd3 34.Re1 still loses to Qd4+! 34...Qxb2! 35.Bxf7+ White is lost also after 35.Rf1 Qh8! 36.Bxf7+ Kxf7! 37.Qxf5+ Ke7! 38.Qe6+ or 38.Re1+ Kd8 39.Rxe8+ Qxe8 40.Kf1 Qe3 41.Qf6+ Kc7 and wins 38...Kd8 39.Qxd6+ Kc8 40.Qxc5+ Kb8-+ and then, for example, 41.Rc1 b3 42.d6 b2 43.Rb1 Qh2+ 44.Kf1 Qh1+ 45.Qg1 Qh7 46.Rxb2 Qd3+ 35...Kg7! But not 35...Kxf7? 36.Qxf5+= with a draw: if Kg7 37.Qd7+ 36.Bxe8 Or 36.Rf1 Re1! 37.Qxg3 Qd4+ 38.Qf2 if 38.Kh2 Rxf1 38...Qxf2+ 39.Kxf2 Rxf1+ 40.Kxf1 b3!-+ and the black pawn is unstoppable: 41.Be6 Kg6 42.g4 fxg4 36...Qxa1+ 37.Qf1 Qd4+ 38.Kh1 b3 There were other winning move as well. For example, 38...Kf8 39.Qe1 Kf8! 40.Bh5 Qe4 White resigned because variations are pretty simple: 40...Qe4 41.Qxe4 or 41.Qa1 b2 41...fxe4 42.Bd1 or 42.Bg6 e3 43.Bd3 b2 42...b2 43.Bc2 e3 followed by 44...e2. 0–1

Head-to-head

The two leaders met each other in a highly anticipated round eleven. They played a full game, but ultimately split the point, in a Sicilian with 3.Bb5+ that never strayed far from the flatline.

1.e4 c5 2.Nf3 d6 3.Bb5+ Bd7 4.Bxd7+ Nxd7 Less popular than the queen recapture, though it is not clear to me quite why. 5.0-0 Ngf6 5...g6 was the move I tried in one outing against one of the players currently in Wijk: 6.c3 Ngf6 7.Re1 Ne5?! A typical idea, but White is not obliged to take by any means! My opponent acheived an advantage but then lost it at some later point: 8.d4 cxd4 9.cxd4 Nxf3+ 10.Qxf3 Bg7 11.e5 dxe5 12.dxe5 Nd5 13.Rd1 e6 14.Nc3 0-0 15.Nxd5 exd5 16.Rxd5 Qb6 17.h4?! Rad8= Jones, G-Fernandez,D London 2016 6.Qe2 6.Re1 e6 7.c3 Be7 8.d4 0-0 9.Bg5 h6 10.Bxf6 Bxf6 11.Na3 cxd4 12.cxd4 Nb6= failed to acheive anything much in Vachier Lagrave,M-Nakamura,H Palma de Mallorca 2017 6...Qc7 7.Rd1 7.c3 is main and we can only assume from his later play that Black wanted e6 8.d4 Be7= or similar, with a fairly solid position and completion of development one move away for both sides. 7...e6 8.d4 8.c4!? was the logical way to implement a 'light square only' pawn structure. To avoid being slightly worse, Black has to make a tough strategic call between ...e5 and ... Ne5. 8...cxd4 9.Nxd4 9.Rxd4!? merited consideration, still trying to set up with c4, e.g. Rc8 10.Na3 Be7 11.Rc4 Qb8 12.Rxc8+ Qxc8 13.c4 9...Rc8 A nice point. Now White would really rather not play Nc3, so his options are limited. 10.Nb5 10.b3!? This leads to the setup White wanted, he just has to see that ...e5 is not favourable. a6 10...e5 11.Nb5 Qxc2 12.Qxc2 Rxc2 13.N1a3 11.c4 Be7 12.Bb2= 10...Qxc2 11.Qxc2 Rxc2 12.N1a3 Rc8 13.Nxa7 Rd8 14.N7b5 14.f3 d5 14...Nxe4 15.f3 Nef6 16.Nxd6+ Bxd6 17.Rxd6 Ke7 18.Rd4 Ne5 19.Be3 Nc6 19...Nd5 is a bit more ambitious; Black's minor pieces are probably slightly better placed so he should think about fighting for an advantage. 20.Rxd8 Rxd8 21.Bc5+ Kd7 22.Nc4 Nd5 23.a4 Whereas in this version, White' bishop has become active so although Black may still be optically for choice, there decidedly isn't an edge unless White messes up. e5 24.a5 Ke6 24...f6 is more patient and keeps open knight re-routings starting with ...Nc7, but should objectively also be nothing. 25.a6 bxa6 26.Rxa6 Kd7 27.b4 A final simplifying combination. Ndxb4 28.Bxb4 Nxb4 29.Rd6+ Ke7 30.Rxd8 Kxd8 31.Nxe5 ½–½

Vidit the favourite to win

The tournament's top seed showed his mettle in today's round twelve, busting out a sharp Leningrad Dutch, to ensure an unbalanced game against tail-ender Olga Girya. He could well expect that Korobov, with white against a much lower rated IM Lucas van Foreest would manage to win, but as luck would have it, Korobov never got a foothold in his game, which liquidated to a drawn endgame.

1.d4 f5 2.g3 Nf6 3.Bg2 g6 4.Nd2 A slightly rare line and maybe one which indicates a degree of fear. White is trying to get e4 in and swap pieces quickly. Normal are c4 or Nf3: 4.Nf3 Bg7 5.0-0 0-0 6.c4 d6 7.Nc3 is the main position of the Leningrad Dutch and now Black chooses between ..c6, ...Nc6 and ...Qe8. 4.Nh3!? Bg7 5.Nf4 is a creative path chosen a few times by Kamsky when forced to play against his own system! 4...Bg7 5.e4 fxe4 6.Nxe4 Nxe4 7.Bxe4 d5 7...0-0 8.Ne2 e5!? 9.dxe5 Nc6 10.f4 d6 is a more adventurous way for Black to play, probably getting dynamic equality 8.Bg2 Nc6 9.Ne2 9.c3 e5 10.Be3 exd4 11.cxd4 0-0 12.Ne2 Bg4 was already really comfortable for Black in Arkell,K -Pruijssers,R chess.com INT 2017 9...Bg4 9...e5!? is a bit sharper, and makes White commit to a central structure change of some kind, otherwise we just end up with the previous note. 10.dxe5 10.0-0 exd4 11.Nf4 0-0 12.Bxd5+ Kh8 10...Nxe5 11.Qxd5 Qxd5 12.Bxd5 c6 13.Be4 Bg4 13...0-0!? 14.h3 Bf3?! Now in my personal experience with this line- from the White side- I was able to slowly neutralise the compensation and go on to win: 15.Bxf3 Nxf3+ 16.Kf1 0-0 17.Kg2 Rae8 18.Be3 Fernandez,D-Sanders,I London 2016 10.f3?! Blunting the bishop cannot be clever and now White has no chance of an opening edge. 10.c3! e5 10...0-0 11.h3 is not really independent, because now the bishop on g4 needs to think of something to do other than take the knight. 11.h3 Bxe2 12.Qxe2 0-0 13.Qb5 Reaching a position which has been played twice from the White side by Croatian grandmaster Nenad Sulava. exd4 14.Qxd5+ Kh8 15.0-0 Qxd5! 15...dxc3?! 16.bxc3 16.Qxd8 Raxd8 17.bxc3 Bxc3 18.Rb1 16...Qxd5 17.Bxd5 Nb4 18.Bg2 White even managed to win in 7 further moves here in Sulava,N-Vallejo Pons,F Toscolano 1997 16.Bxd5 Rad8 17.Bg2 17.Bxc6 bxc6 18.cxd4 Bxd4= Sulava,N-Santo Roman,M Saint Affrique 1998 17...Rf7!? Black doesn't take the pawn yet, and just improves. It is not clear to me whether White has some way to continue pressing. 10...Bf5= 11.0-0 Qd6 12.c3 12.Bf4 Qb4 was presumably what White was afraid of, but the machine informs us that the pawn sacrifices are fully playable for White. 13.c3 Qxb2 14.g4 Bd7 15.Rb1 Qxa2 16.Rxb7 12...e5?! 12...0-0-0 first was a more stable order. 13.Be3 Not leading to a disadvantage, but not particularly incisive either. 13.dxe5 Nxe5 14.Nd4 0-0-0 Else f4 and Re1 motifs come into play. 15.Nxf5 gxf5 16.Qc2 13...0-0-0 14.Qd2 h5 15.Rae1?! 15.Bg5 was worth considering, but if Black had wished to emulate the play of his countryman, then in addition to normal moves leading to a slightly more pleasant position (...Bf6, etc) there was also the violent h4!? 15...h4 16.g4 h3! Else White consolidates by playing h3 herself. 17.Bh1 Bd7 18.Rd1 Rde8 19.dxe5? 19.Rfe1 still asks the question of how Black is going to try and break in, although the obvious choices like Rhf8 still leave Black quite obviously better 19...Qxe5 20.Bd4 Nxd4 21.Nxd4 Bxg4? Maybe marring the victory a bit. 21...Qd6-+ or similar left White with essentially no moves 22.Rde1 22.fxg4 Bh6-+ 22.Rfe1! was the better rook move, leaving White's king a flight square. Qh5 23.Rxe8+ Rxe8 24.fxg4 Qxg4+ 25.Kf2 25.Kf1 Rf8+ 26.Nf3 Rxf3+ 27.Bxf3 Qxf3+ 28.Ke1 Bf6 Black is better, with his adequate number of pawns for the exchange plus continuing attack, but he has to win again. 25...Bh6 26.Qxh6 Qxd1 27.Qxh3+ Kb8 28.Bf3 Here White seems to be surviving with some machine precision, though in a game you would still take Black. 22...Qh5 23.Rxe8+ Rxe8 24.fxg4 Qxg4+ 25.Kf2 Qh4+ 26.Kg1 After 26.Kf3 Bh6 also wins trivially 26...Bh6 Not a completely flawless game by Black (moves 9, 12 and 21) but a very nice finish nevertheless. Meanwhile, both sides- and most Dutch players for that matter- should probably pay a bit more attention to this sideline. 0–1

After this clutch win from Vidit, the pressure is on Korobov to go for broke with black in the final round, to have any chance at the coveted spot in next year's Masters. It's unlikely that Vidit will lose with white given how well he is playing, but should they end up tied, the winner will be decided on the player's Sonneborn-Berger score — the second tiebreak criteria, since their direct encounter was drawn.


The Caro Kann is a very tricky opening. Black’s play is based on controlling and fighting for key light squares. It is a line which was very fashionable in late 90s and early 2000s due to the successes of greats like Karpov, Anand, Dreev etc. Recently due to strong engines lot of key developments have been made and some new lines have been introduced, while others have been refuted altogether. I have analyzed the new trends carefully and found some new ideas for Black.
