Biel Rd 9: All wins and all to play for

Run-away leader Maxime Vachier-Lagrave was brought to an abrupt halt by Anish Giri in Round 9 of the Biel Chess Festival and now goes into the final round only half a point ahead of Hou Yifan and Radoslaw Wojtaszek. The latter two both won on a day of novel and risky openings, with two game-changing blunders only adding to the spectacle.

The game of the day was between Radek Wojtaszek and Pentala Harikrishna. The Pole played the unusual 7.Bb5 line of the Grünfeld Defence (don’t miss Peter Svidler’s epic video series on the opening). Wojtaszek pressed his opponent relentlessly and went on to score an impressive victory:

1. d4 ♘f6 2. c4 g6 3. ♘c3 d5 The Grünfeld is one of the most fashionable lines among the chess elite. It ensures double-edged positions in which all three results are possible.

4. cxd5 ♘xd5 5. e4 ♘xc3 6. bxc3 ♗g7 7. ♗b5+ Wojtaszek opts for a secondary line. The idea is to deprive the knight of the c6-square.

7. ♗c4 is one of the most ancient lines. White develops his knight to e2.

7. ♘f3 c5 8. ♖b1 is a more modern line.

7... ♘c6 This has only been played 30 times. The main lines are

7... c6 , with more than a 1000 games in the database, or

7... ♗d7

8. ♘f3 0-0 9. 0-0 ♘a5 This strikes me as quite logical. Sooner or later Black has to break with c5 in order to destabilise the white centre. Moreover, the c4-square can be good for the black knight in future.

10. ♗f4! This move by the Pole turns out to be a novelty! The white bishop usually heads to e3 in the Grünfeld, but that's due to the fact that a certain pressure exists on the d4-point (a knight on c6 hitting d4). In this case the pressure on the centre isn't overwhelming so the bishop can head for a more active square.

10... ♗d7 11. ♗e2

11. ♗xd7 would help Black to control the light squares. For example, 11... ♕xd7 12. ♖b1 b5!

11... c5 A logical and expected reaction.

12. d5

12. ♖c1 , maintaining the tension, is also logical.

12... ♗g4

12... ♗xc3 13. ♖c1 ♗g7 14. ♖xc5 and White keeps a slight advantage due to his better pawn centre. For example 14... ♖c8 15. ♖xc8 ♗xc8 16. ♕c2+/=

13. e5 Brave. If Black manages to destablise White's centre it'll all be over. Still, it's difficult to resist advancing your central pawns :)

13. ♕d3

13... ♕d7 14. ♖e1 ♖ad8

14... b5 is interesting.

15. h3! A good move.

15. c4 ♗xf3! 16. gxf3 e6 with good play for Black.

15... ♗f5 16. c4 White has now managed to consolidate his centre.

16... e6 17. ♕d2 b6 18. d6 White's edge is growing.

18... ♗e4 It was necessary to regroup the bishop, as on f5 it had to fear a possible g4 at any moment.

19. ♘g5 ♗b7 20. ♖ad1 ♔h8

20... h6 21. ♘f3 ♗xf3 22. ♗xf3 ♘xc4 23. ♕c3 ♘a5 was perhaps more convincing for Black. At the cost of a pawn White keeps a slight advantage thanks to his bishop pair and protected passed pawn.

21. ♕e3 ♘c6 22. ♘f3 ♘b4 23. ♖d2 ♕a4 Black has lost a lot of tempi and should instead have reacted much sooner with f6. Now the danger is no longer positional but getting mated.

24. ♗d1 ♕a6 25. ♗g5! ♖d7 26. ♗f6 There are already plans in the air for something like Nh2, Ng4, Bxg7, Qh6+ and Nf6 mate.

26... ♗xf6

26... ♕xc4 27. ♕h6 Wow! 27... ♖g8 28. ♘g5 And it's over!

27. exf6 ♗xf3 28. ♗xf3 ♕c8? 29. ♕e4

29. ♕g5 would have been crushing, with Re4, Rh4 and mate almost unstoppable. The black position is still extremely unpleasant, though, and the Indian found himself in serious time trouble.

29... ♖g8 30. a3 ♘a6 31. ♗d1 ♘b8 32. ♗a4 ♖dd8 33. g4 ♕a6 34. ♕c2 ♕b7 35. ♕c3 ♘c6? Another mistake which is exploited by Wojtaszek.

36. ♗xc6 ♕xc6 37. ♖xe6! ♖gf8

37... fxe6 38. f7+ ♖g7 39. d7!+−

38. ♕e5 Defending d6 and giving the e6 rook the freedom to move.

38... ♕f3 39. ♕e3 ♕c6 40. ♖e7 ♖d7 And Harikrishna resigned due to the threat of Qh6 and Re8. A great game by the Polish player!

1-0

Hou Yifan came up against the Caro-Kann of Alexander Motylev. The European Champion had no problems whatsoever and even achieved a slightly better position, but things aren't going well for Alexander in Biel - everything turned on the following mistake:

31... ♘d6? Today seems to be the day when the d6-square was cursed for black knights.

31... ♘c5! , for example, and the position is totally equal.

32. ♘f4! Black simply can't avoid losing a pawn.

32... ♘c4+ 33. ♔c2 ♘e5 34. ♖e3 ♔d6 35. ♖g3 And the g6-pawn falls.

35... ♖f8 36. d4 ♖c8+ 37. ♔d1 ♘d7 38. ♖xg6+ And the rest was already a question of technique. Hou Yifan didn't miss her chance and is now only half a point behind the leader!

1-0

One of the sub plots of the upcoming Olympiad will be whether Hou Yifan can catch up with Judit Polgar. There's isn't far to go!

The leader, Maxime Vachier-Lagrave, had to suffer early on after being caught out in Anish Giri’s preparation.

He thought for 43 minutes on move 8, but ultimately achieved a decent position before he followed Motylev’s lead and spoiled his position with the same Nd6 move. Giri was able to exploit the slip and pick up a full point:

36... ♘d6? A blunder just as in the Motylev game. The knight ending is lost since White's king is much more active than Black's.

36... ♖e8+! 37. ♔d3 ♔g7 While Black is undoubtedly still somewhat worse he should be able to hold the position due to the fact his rook can become active at any moment. In the absence of rooks the white king is much stronger.

37. ♖b8 ♖xb8 38. ♘xb8 ♘xc4+ 39. ♔d4 ♘b6 40. ♘xc6 a4 41. ♔c5 ♘c8 42. ♔b4 ♘b6 43. ♔c5 ♘c8 44. ♔b4 ♘b6 45. ♔b5 ♘d5 46. ♔xa4 ♔g7 47. ♘b4 ♘e3 48. ♔b5 ♔f7 49. a4 ♔e6 50. a5 ♔d7 51. a6 ♔c8 52. ♔c5 And Black resigned.

1-0

Daniel King presented another excellent round-up of the day’s play, with comments from the players:

Who will dare put a knight on d6 in the final round?! The standings are now as follows:

1.Vachier-Lagrave, Maxime27661½½.10½½½12784
2.Hou, Yifan26290½½½1½½.½152778
3.Wojtaszek, Radoslaw2733½.½½0½½11½52751
4.Giri, Anish2750010½1½0½1.2711
5.Harikrishna, Pentala2726½½½.½01½0½42681
6.Motylev, Alexander2698½0½00½0.1½32592

Maxime's lead has been cut to a mere half point, with the pairings for Thursday's 10th and final round as follows:

  • Pentala Harikrishna - Hou Yifan                                 
  • Alexander Motylev - Anish Giri                                 
  • Maxime Vachier-Lagrave - Radoslaw Wojtaszek

As you can see, both Hou Yifan and Radoslaw Wojtaszek have the black pieces, but as Wojtaszek takes on the leader he has his tournament fate in his own hands.
