Biel Rds 7 & 8: Vachier-Lagrave on the brink

France’s Maxime Vachier-Lagrave scored the only win in rounds 7 and 8 of the Grandmaster Tournament in Biel to put himself a full 1.5 points clear of the field with only two rounds to go. Spanish IM Pepe Cuenca takes a look at that crucial win against Alexander Motylev and other highlights of the only super-tournament still in progress.

The first game to finish in Round 7 was the encounter between Anish Giri and Pentala Harikrishna. The Indian played an unconventional opening line recommended by his grandmaster compatriot Surya Ganguly.

After Giri committed an inaccuracy he was left with no choice but to sacrifice his queen. Nevertheless, he managed to go on to get excellent compensation for parting with his most powerful piece. 

Let's take a look at that passage of play:

13. ♕a4 Giri simply missed the continuation in the game, as he admitted in the post-game interview.

13... ♖xd4! 14. b3

14. ♗xc6 ♖xc4! 15. ♕xa7 bxc6−+ with a clear advantage.

14... ♘e4 The queen is already in difficulty, but Giri finds a way to gain good compensation.

15. ♗b2 After the other option

15. ♗xe4 ♖xe4 16. ♗e3 a6−+ Black has an extra pawn, a healthy position and the white queen can be attacked at any moment, with no good squares for it to retreat to.

15... ♘c5 16. ♕xc6! bxc6 17. ♗xd4 White has a rook and pawn for the queen. The bishop pair and the option of using the c-file to attack Black's weak pawns make the position more or less balanced.

17... ♘e4 18. ♖ae1 f5 19. f3 ♕d5 20. fxe4 ♕xd4+ 21. ♔h1 ♗b4 22. ♖d1 ♕c3 23. ♖c1 ♕d4 24. ♖cd1 ♕c3 25. ♖c1 ♕d4 26. ♖cd1

1/2-1/2

The next game to finish was the crucial confrontation between Motylev and Vachier-Lagrave. That saw a Najdorf Sicilian in which White sacrificed a piece, but some exquisite defensive allowed the French tournament leader to come out on top.

Let's take a look at the full game:

1. e4 c5 2. ♘f3 d6 3. d4 cxd4 4. ♘xd4 ♘f6 5. ♘c3 a6 The Najdorf Defence never goes out of fashion!

6. ♗e3 ♘g4 7. ♗g5 h6 8. ♗h4 g5 9. ♗g3 ♗g7 10. ♗e2 h5 11. h4 ♘c6 You usually first play

11... gxh4 and here either 12. ♗xh4 or (12. ♖xh4 have been played.)

12. ♘b3 gxh4 13. ♗xh4 And they've transposed. Let's take a look at the position. Clearly it's double-edged, as are almost all the positions that arise out of the Najdorf. White has a better pawn structure (2 "islands" compared to Black's 3), and is a little better developed. Black, meanwhile, has an active knight on g4 and his bishop on g7 is a monster!

13... ♗e6 14. ♕d2 ♕b6 15. ♘d5 ♗xd5 16. exd5 Both players are still in book.

16. ♕xd5? ♗xb2 17. ♖b1 ♗f6⁉−+

16... ♘d4 17. c3

17. ♘xd4 was played in Kotronias-King, 1993 (1-0) Vachier also evaluated the capture on d4 and thought that after 17... ♗xd4 18. 0-0 the best way to equalise was 18... ♘e3 with the idea of Nf5. 19. ♖fe1 ♘f5 20. ♖ad1 ♗c5+/=

17... ♘f5 18. ♗xg4 The best move. Black was threatening to capture on h4 and f2.

18... hxg4 19. ♕g5 Correct. Defending h4 and attacking f5.

19... e6 20. ♕xg4

20. dxe6 was perhaps a little more subtle: 20... fxe6 21. ♕xg4 ♔f7 22. 0-0-0 ♖ag8 and according to the engines this complex position is "equal".

20... ♗f6 21. dxe6 Very tempting, but better was

21. g3

21... ♘xh4 22. 0-0-0 ♕xf2 23. ♖xd6

23. g3 ♕e3+ 24. ♔b1 ♕xe6 25. ♖de1 ♗e5 26. ♖xh4 0-0-0=

23... ♖d8 24. ♖xd8+ ♗xd8 25. ♘d2 ♕e3 26. exf7+ ♔xf7 The position is extremely complex - two pawns for the piece and Black's king is very open. Vachier-Lagrave demonstrates excellent defensive technique.

27. ♖f1+ ♗f6 28. ♕d7+ ♕e7 29. ♕d3

29. ♕g4! was better, preventing the black king from escaping on the g-file as it does in the game. How easy it is to analyse when it's not you sitting at the board!

29... ♔g7 30. ♘e4 ♗e5 31. ♕e2 ♘g6 32. g3 ♖e8 Black has consolidated and it's now a question of technique.

33. ♕g4 ♕e6 34. ♕h5

34. ♕xe6 The best option was to suffer in this ending.

34... ♕xa2 35. ♘c5? ♕a1+

0-1

Hou Yifan had her chances against Radek Wojtaszek, but the Polish no. 1 eventually managed to find salvation in the following ending a pawn down.

You can watch Grandmaster Daniel King's brief round-up of the day's play, with player comments, below:

Round 8

Tuesday saw a very even fight on all boards, with three draws finally agreed. We’ve picked out the following example of a common plan: regrouping pieces and looking for a diagonal for a bad bishop. In this case Women’s World Champion Hou Yifan applies the idea in its purest “stonewall style”, bringing the bishop from c8 to h5, after which she had few problems drawing against the tournament’s front-runner. 

15. ♘c3 ♗d7 The Chinese World Champion's manoeuvre begins.

16. ♗d3 ♗e8 17. ♕e4 f5 18. ♕e3 ♗h5 19. ♘e2 ♗xf3 20. ♕xf3 The manoeuvre is complete. Black has exchanged her bad bishop for the good knight, which controlled e5 and defended d4. From this point on the position has simplified and Hou Yifan draws without difficulties.

20... ♘xd4 21. ♘xd4 ♖xd4 22. ♗xf5 ♖xd1+ 23. ♕xd1 ♖f8 24. ♗e4 ♗b6 25. ♗f3 ♕f6 26. ♕e2 ♗d4 27. b3 ♔h8 28. h3 b6 29. ♖c6 ♗e5 30. ♕e4 ♕f5 31. ♔f1 ♖d8 32. h4 ♔g8 33. ♕xf5 exf5 34. ♗h5 ♗f6 35. ♖c7 ♗xh4 36. ♖xa7 ♔h7 37. ♖a6 ♖d6 38. a4 ♗e7 39. ♗e2 ♔g6 40. a5 bxa5 41. ♖xa5

1/2-1/2

Hou Yifan has looked absolutely at home in Biel and is now up to 2659 (+30 for July!) on the live rating list. We're proud she recently filmed a video series for chess24 - Hou Yifan: My Career So Far | photo: official website

Daniel King again provided a brief report on the day's action:

After eight rounds we still have a “chasing pack” of three players, though only a win for Anish Giri in Round 9 is likely to cast any doubt on Maxime Vachier-Lagrave’s ultimate coronation:
