Tata Steel Chess Masters, Wijk aan Zee (1) 2015

Notes by Boris Schipkov

1. d4 Nf6 2. c4 g6 3. g3

After 3.g3 Black can choose between the King's Indian Defence 3...d6, Modern Benoni Defence 3...c5 4.d5, and Gruenfeld Defence 3...d5 or 3...c6, followed by 4...d5. The most solid line is the Gruenfeld with 3...c6 and 4...d5.
4. Bg2 d5 5. Nf3 Bg7 6. O-O O-O

7. b3
A slightly strange move. After this Black can destroy White's pawn centre with 7...dxc4 and 8...c5. The alternatives are 7. cxd5 and 7. Qb3.
Of course, World No.2 Fabiano Caruana plays the best continuation.
8. bxc4 c5!

9. Bb2
Now 9. d5 is bad, because after 9...Ne8 Black simply wins the a1-rook or the knight. White can try to keep the pawn centre with 9. e3, but after 9...Nc6 10. Bb2 Qb6 11. Qe2 cxd4 12. exd4 Bg4 13. d5 Bxf3 14. Bxf3 Nd4 15. Bxd4 Qxd4 16. Nd2 Nd7 17. Nb3 Qe5 18. Rac1 Qxe2 19. Bxe2 b6 the endgame is equal, and Black can attack the weak c4-pawn, Rodriguez de Castro, A - Martos de la Vega, A, Mostoles op 2014.
9...Qb6 10. Qc1
Another move is 10. Qb3.
10...cxd4 11. Nxd4

White's pawn centre was successfully ruined. Here Black has two interesting and good plans: 1. To attack the c-pawn after 11...Bd7 with the rook and queen on the c-file; 2. To seize the open d-file and b-file with the rooks after 11...Nc6 12. Nxc6 bxc6. Fabiano Caruana prefers 11...Nc6. In the game Dizdarevic,E - Svidler,P, Bled ol 2002 Peter Svidler played 11...Bd7!? 12. Nd2 Nc6 13. c5 Qc7! (13...Qa6?! looks somewhat worse, 14. Qc4 Qxc4 15. Nxc4 Rfc8 16. Rab1 Rab8, Shankland,S - Wei Yi, Wijk aan Zee B 2015, and 17. Rfd1!? deserves attention) 14. Nb5 Qc8 15. Ne4 Nxe4 16. Bxe4 Ne5= 17. Nd4 Rb8 18. Rb1 Qc7 19. Qc2 Rfc8 20. Rfc1 Qa5! 21. Qc3 Qxc3 22. Rxc3 Nc6 23. Nxc6 Bxc6 24. Rc4? (24. Re3) 24...b5, 0-1, and White resigned, because after 25. Rb4 (25. cxb6 Bxe4 26. Rxe4 Rxb6) 25...a5 Black wins the exchange.
12. Nxc6 bxc6 13. Nd2

A novelty. After 13...Bg4?! 14. Nb3 (14. Rb1!?) 14...Bxe2 15. Re1 Bd3, Ding,L - Gelfand,B Moscow 2014, White could try 16. Bd4 Qa6 17. Re3 Bf5 18. Rxe7, with a small advantage. Or 13...Be6 14. Rb1 Qa6 15. Ba3?! (Bc3!? is better) 15...Rfe8 16. Rb3 Nd7, with equality in Goldin,A - Yandemirov,V, Elista 1995.
14. Nb3 Rac8
14...Rfd8! is more precise, 15. Bc3 (15. e4?! Bxe4 16. Bxe4 Nxe4 17. Bxg7 Kxg7) 15... a5 16. c5 Qc7 17. Rd1 Rxd1+ 18. Qxd1 a4 19. Nd2, with equality.
15. e4! Be6
If 15...Bxe4? then 16. Bxf6 Bxf6 (16...Bxg2 17. Bxg7 Bxf1 18. Bxf8) 17. Bxe4 Bxa1 18. Qxa1, and White has two light pieces for a rook.
16. e5?!
White tries to block the g7-bishop, but the text is a mistake. The main problem of this move is that the kingside becomes weak, because White must defend the e5-pawn with the f4-pawn, and therefore the f2, f3, e3 squares will be weaknesses. Pawns cannot go back, so the weaknesses remain forever. 16. Rb1! is better, 16...Qa6 17. Nc5 Qxc4 18. Qxc4 Bxc4 19. Rfc1 Be2 20. Rc2 Bh5 21. h4 h6 22. Bxf6 exf6 23. Bh3 f5 24. exf5 gxf5 25. Bxf5, with a slight edge to White.

17. Re1?!
Again a dubious move. White could try 17. c5 Qa6 18. Re1 Rfd8, with counterplay.
Black fixes White's c4-pawn and can attack it in the near future.
18. Nd2
After 18. Qc3 Qa6 19. Na5 Rc7 20. Qa3 Rb8 21. Bc3 Black grabs the pawn with 21...Bxc4 22. Nxc4 Qxc4 23. Rad1 Nb6 24. Re4 Qe6 25. Ree1.
Black can seize the open d-file with 18...Rfd8!?.
19. Re3 Rb8 20. Ra3
White can play 20. f4 at once.
20...Qb6 21. Rb3 Qc7 22. f4 Nb6

23. Rb1!
Ding Liren fights for the open b-file.
23...Rbd8 24. Bc3
24. a4!? is interesting, trying to open the way for rooks with a5, followed by Rb7.
Black can continue 24...f6!? immediately, with the idea of to seize also the e-line with the rook.
25. Bf1?!
A mistake. White must counterattack with 25. Rb5.

Black activates the light-squared bishop and plans to undermine White's pawn chain with 26...f6. White has many weaknesses in his camp, especially on the kingside.
26. Ra1 f6!
Very strong, intending to revive the g7-bishop and f8-rook.
27. exf6 exf6 28. Rb5 Na4 29. Nb3
After 29. Ba5!? Qd4+ 30. Kh1 Rde8 31. Rb3 Black has a small advantage, but the knight controls the e4 and f3 squares.
29...Nxc3 30. Qxc3

A multy-purpose vigorous move: Black seizes the light long diagonal and plans to seize the dark long diagonal after ...f5 and the e-file with ...Rfe8 to attack White's king.
31. f5?!
White sacrifices a pawn, trying to stop Black's attack. In the case of 31. Re1 f5 32. Qe3 Rfe8 33. Qf2 Bc6 34. Rxc5 Rxe1 35. Qxe1 Rb8 White must give the rook for the bishop 36. Rxc6 (36. Bg2 Bd4+ 37. Nxd4 Qxd4+ 38. Qf2 Qa1+ 39. Bf1 Rb2) 36...Qxc6 37. Qd2 Bf8. Or 31. Nxc5 Qc6 32. f5 a6 33. Qb3 (33. Ra5 Qb6) 33...Kh8 34. Ra5 Bxf5 35. Bg2 Qd6, and Black intends ...Qd2 and ...Rfe8, winning.
31...Qxf5 32. Re1 Rfe8 33. Rxc5

Black can sacrifice the queen with 33...Qxc5+ 34. Nxc5 f5 35. Qe3 Bd4, winning.
34. Qc1 f5 35. Qf4 Re7
Black has two strong bishops, two real monsters, two powerful rooks and the mighty queen. 35...a5 and 35...Bc6 are also possible.
36. h4 a5!
A great move to finish the game. Black threatens ...a4.

37. Rxa5
If 37. Nxa5? then 37...Bd4+, winning the rook. After 37. a4 Qxa4 38. Re3 Ra8 39. Rb5 Qa3 40. Kh2 Be5! 41. Qf2 (41. Rxe5 Qb2+) 41...Qd6 42. Nd2 f4! Black grabs the exchange and wins the endgame, 43. Nxe4 fxe3 44. Qxe3 Qd4.
The bishop fork.
38. Rd5 Qa7+ 39. Kh2 Rxd5 40. cxd5 Bxe1
White resigned. 0-1
