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.
The dynamic play based on a strong strategic foundation has always fascinated me, and in these DVDs I have suggested the lines which I personally prefer and employ in practice.
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.

Modern Benoni but are more important for the King's Indian (where Black's plan

Indian move order.a6Other important options are ...Re8 and ...h5.11.a411.Bxh6is answered byNxe4!followed by ...Qh4+11...h5Now 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)

know them.Note that Kasparov in his games preferred11...Re812.Nge2

option is13.Nf413...Ne514.Be2Nh7Again Black had a choice, between
this move and 14...Re8, 14...h4.15.h3Still 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.f4But

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.e4c52.Nf3d63.Bb5+Bd74.Bxd7+Nxd7Less popular than the queen
recapture, though it is not clear to me quite why.5.0-0Ngf65...g6
was the move I tried in one outing against one of the players currently in
Wijk:6.c3Ngf67.Re1Ne5?!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.d4cxd49.cxd4Nxf3+10.Qxf3Bg711.e5dxe512.dxe5Nd513.Rd1e614.Nc30-015.Nxd5exd516.Rxd5Qb617.h4?!Rad8=Jones,

Vachier Lagrave,M-Nakamura,H Palma de Mallorca 20176...Qc77.Rd17.c3
is main and we can only assume from his later play that Black wantede68.d4Be7=or similar, with a fairly solid position and completion of
development one move away for both sides.7...e68.d48.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...cxd49.Nxd49.Rxd4!?merited consideration, still trying to
set up with c4, e.g.Rc810.Na3Be711.Rc4Qb812.Rxc8+Qxc813.c49...Rc8A nice point. Now White would really rather not play Nc3, so his
options are limited.10.Nb510.b3!?This leads to the setup White wanted,
he just has to see that ...e5 is not favourable.a610...e511.Nb5Qxc212.Qxc2Rxc213.N1a311.c4Be712.Bb2=10...Qxc211.Qxc2Rxc212.N1a3Rc813.Nxa7Rd814.N7b514.f3d514...Nxe415.f3Nef616.Nxd6+Bxd617.Rxd6Ke718.Rd4Ne519.Be3Nc619...Nd5is a bit more ambitious;
Black's minor pieces are probably slightly better placed so he should think
about fighting for an advantage.20.Rxd8Rxd821.Bc5+Kd722.Nc4Nd523.a4Whereas 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.e524.a5Ke624...f6is more patient and keeps open knight
re-routings starting with ...Nc7, but should objectively also be nothing.25.a6bxa626.Rxa6Kd727.b4A final simplifying combination.Ndxb428.Bxb4Nxb429.Rd6+Ke730.Rxd8Kxd831.Nxe5½–½
The Rossolimo Variation of the Sicilian Defence (1.e4 c5 2.Nf3 Nc6 3.Bb5) is always an excellent choice with White if you want to avoid the deeply analysed main lines of the Open Sicilian. Alexei Shirov provides you with the requisite understanding of the opening's subtleties, by annotating extensively his most important games in this variation. During his career, he has played the 3.Bb5 system with both colours and he shares with you on this DVD his valuable experience.
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.d4f52.g3Nf63.Bg2g64.Nd2A 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.Nf3Bg75.0-00-06.c4d67.Nc3
is the main position of the Leningrad Dutch and now Black chooses between ..c6,

central structure change of some kind, otherwise we just end up with the

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.Bxf3Nxf3+16.Kf10-017.Kg2Rae818.Be3Fernandez,D-Sanders,I London 201610.f3?!
Blunting the bishop cannot be clever and now White has no chance of an opening
edge.10.c3!e510...0-011.h3is not really independent, because now
the bishop on g4 needs to think of something to do other than take the knight.11.h3Bxe212.Qxe20-013.Qb5Reaching a position which has been played

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
On some occasions it would yield you a perfect win, on others it could cause you "shameful" defeats. This DVD is intended in the first line to offer strategical guidance for Black, based on the examination of the most typical structures.
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.
