**Round 5**

**Van Wely - Svidler [D85]**

**1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. Nf3 Bg7 5. cxd5 Nxd5 6. e4
Nxc3 7. bxc3 c5 8. Rb1 O-O 9. Be2 cxd4 10. cxd4 Qa5+ 11. Bd2 **

The rivals begin their opposition with one of the main lines
of the Gruenfeld Defence. Trying to avoid an exchange of the
queens, White sacrifices the pawn and hopes to gain profit in the
future from his better development and mighty pawn centre.

**11... Qxa2 12. O-O Bg4 13. Bg5 **

In order to understand better the further events it’s useful
to give a look now at how this position developed in the game
Bacrot - Illescas Cordoba (Pamplona, 1997). After 13. Be3 Nc6 14.
d5 Bxf3 15. Bxf3 Ne5 16. Rxb7 Black played 16... a5!, staking on
the passed a-pawn, and the following complications 17. Rxe7 a4
18. Bd4 Nxf3+ 19. gxf3 Bxd4 20. Qxd4 a3 21. Kg2 Qb2 22. Qxb2 axb2
23. Rb1 Rfb8 brought him to a rook endgame where his far advanced
pawn on b2 defended him quite reliably from any possible
troubles.

**13... h6 14. Be3 Nc6 15. d5 Bxf3 16. Bxf3 Ne5 17. Rxb7 **

**17... a5! **

It looks as if this move did not occur previously in this
position. You see that the only difference from the above
mentioned game Bacrot - Illescas Cordoba is in the position of
Black’s h-pawn on h6 instead of h7. Previously Black played
17... e6 in order to equalise. After 18. dxe6 Nxf3+ 19. Qxf3 Qxe6
20. Rxa7 Rxa7 21. Bxa7 Re8 22. Re1 f5 he usually managed to
obtain a draw without particular problems, but it seems that in
case of 18. Qe2!? the position would be not so clear.

**18. Bc5 **

After 18. Rxe7 a4 to be followed with 19. Bd4 Nxf3+ 20. gxf3
Bxd4 21. Qxd4 a3 the play could have developed similarly to the
previously mentioned game, and the difference in the position of
the h-pawn would not influence the estimation.

**18... a4 19. Bxe7 Rfb8 20. Rxb8+ Rxb8 21. d6 **

It occurred to White that his d-pawn is also passed.

**21... Qe6 22. Qxa4 **

Practically this move was necessary. After 22. Be2 a3 23. Qa4
a2 24. f4 Rb1 Black’s a-pawn passed.

**22... Nxf3+ 23. gxf3 Qh3 **

An unpleasant threat of 24... Be5 makes White to part with one
of his two extra pawns and agree to a perpetual check.

**24. Qa5 Qxf3 25. Qd5 Qg4+ 1/2-1/2 Draw.**

**Gelfand - Gallagher [E94]**

**1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. Nf3 d6 5. e4 O-O 6. Be2 e5
7. O-O Na6 8. Re1 c6 9. Bf1 Bg4 **

As for B. Gelfand, in this variation of the King's Indian
Defence he prefers struggling for an equalisation with 9... exd4
10. Nxd4 Ng4 11. h3 Qb6 12. hxg4 Qxd4 13. Bf4 Qxd1 14. Raxd1 Be5
15. Bh6 Re8 which he played, for instance, in the game Van der
Sterren - Gelfand (Wijk aan Zee, 1998).

**10. d5 Ne8 **

Black hurries to remove the knight as soon as possible to
avoid a binding. In case of 10... c5 11. h3 Bd7 he had to reckon
with 12. Bg5!. The Swiss grandmaster has already some negative
experience in this line. After 12... h6 13. Be3 Be8 14. Qd2 Kh7
15. a3 Nd7 16. g3 f5 17. exf5 gxf5 18. Nh4! Black encountered
problems in the game Tukmakov - Gallagher (Lugano, 1999). A
similar situation appears often after 10... Nb4 11. Be2 a5 12.
Bg5!.

**11. h3 Bd7 **

**12. dxc6**

A new move. 12. Rb1 c5 13. a3 f5 14. b4 f4 which occurred
previously provided Black with a good play.

**12... bxc6 13. Bg5!**

A helpful intermediate move. The diagonal a1-h8 is locked
twice for the bishop g7.

**13...f6 14. Be3 c5 **

This move complies with Black’s plan to occupy the square
d4, besides, in case of a delay (14... f5 or 14... Nac7) White
could have gained an advantage with 15. c5!.

**15. Nd5 Nac7 16. b4 **

In case of 16. Nxc7 Qxc7 17. Qd5+ Kh8 18. Qxa8 White won
Black’s rook, but lost his own queen after 18... Bc6.

**16... Ne6 **

A capture 16... cxb4 made it already possible to play 17. Nxc7
Qxc7 (in case of 17... Nxc7 the way to an advantage was connected
with 18. Qxd6) 18. Qd5+ Rf7 19. Qxa8, because in case of 19...
Bc6 there was 20. Qxa7.

**17. Rb1 Kh8 **

Another useful move. In case of 17... cxb4 18. Nxb4 f5 19.
exf5 gxf5 20. Qd5 White’s position was preferable, while 17...
Nd4 allowed him to get a better play after18. bxc5 dxc5 19. Nxd4
cxd4 (19... exd4 20. Bf4) 20. Bd2 owing to his knight, occupying
a strong position on d5.

**18. Nd2 f5 19. exf5 gxf5 20. f4 **

A standard but rather important move. 20. Nb3!? deserved
attention, not fearing 20... f4 21. Bd2.

**20... cxb4 21. Rxb4 Bc6 22. Nf3 Qa5 23. Rb1 **

White begins a combination, longing to keep the eluding
advantage. After 23. Qd2 N8c7 24. Rd1 Bxd5 25. cxd5 Nxf4 the play
became equal.

**23... N8c7! **

Black refuses to take the sacrificed pawn. After 23... Qxa2
White had the move 24. fxe5 (Black was OK after 24. Nb4 Bxf3 25.
Qxf3 e4) 24... dxe5, and then 25. Nxe5! Bxe5 26. Bf2 Bh2+ (in the
endgame after 26... Ba4 27. Qe2 Qxe2 28. Rxe2 White’s chances
were also better) 27.Kxh2 Qxf2 28. Rxe6 White had an advantage.

**24. fxe5?! **

White surrenders the centre. Probably he had to agree to the
line 24. Nxc7 Qxc7 25. c5 dxc5 26. Nxe5 Bxe5 27.fxe5, because he
had a sufficient compensation for the pawn in form of the
advantage of two bishops and the play on black squares.

**24... dxe5 25. Ne7?! **

This move looks too artificial, hardly it can be absolutely
correct. On the other hand, in case of a passive 25. Bf2
Black’s pawns began an advance with 25... e4 and he had an easy
play.

**25... Be4 26. Nh4 **

White has to continue playing in the gambit style, because
after 26. Rb3 Rae8 his knight would have perished in Black’s
camp.

**26... Nf4 **

A good continuation, but it’s interesting what was prepared
by White in case of a mere 26... Bxb1. After 27. Qh5 Rf6 28. Rxb1
(in case of 28. Nhg6+ Rxg6 29. Nxg6+ Kg8 30. Ne7+ Kf8 31. Rxb1
Kxe7 32. Qxf5 h6 White seemed to have no sufficient compensation
for the piece) 28... Nf4 29. Bxf4 Qc5+ 30. Kh1 Qxe7 31. Re1
(there was no 31. Bg5 because of 31... Qf7), and now a mere 31...
Qf7 repulsed White’s threats. 26... f4!? looked quite
reasonable too, because after 27. Qh5 Rf6 there was no 28. Bb6
(after 28. Bf2 Bxb1 29. Rxb1 Rh6 Black repelled the attack and
kept the material advantage) because of 28... axb6 29. Rxe4 Qc5+,
Black keeping an extra piece.

**27. Bxf4 Qc5+ 28. Be3 Qxe7 29. Qh5 **

**29... Qf7? **

Black had to have ventured on 29... f4 30. Bxf4 (if 30. Bb6,
then after 30... Bxb1 31. Rxb1 Qf7 he got an extra exchange),
because then he would have 30... exf4!, and after 31. Bd3 Bd4+
32. Kh1 Be3 he escaped all threats and kept the extra material.
At the same time, the capture 30... Rxf4 allowed White to develop
a strongest attack with 31. Rxe4! Qc5+ 32. Kh2 Rxe4 33. Bd3 Qd4
34. Ng6+ Kg8 35. Ne7+ Kf8 (in case of 35... Kh8 there was 36.
Rb3!! with the threat of 37. Nf5!) 36. Qxh7 Qxd3 37. Ng6+ Ke8
(there was no 37... Kf7 because of 38. Nxe5+ Rxe5 39. Qxd3) 38.
Qxg7.

**30. Qxf7 Rxf7 **

The position is approximately equal. White’s chances are
probably some better owing to his passed c-pawn and the control
over the open d-file.

**31. Rbd1 Bf6 32. Nf3 Rg8 33. Kh2 Ne6 34. Rd6 Bxf3 **

Black wants to simplify the position. After 34... Re7 he had
to reckon with 35. c5 to be continued with 35... Rc8, whereafter
White had an unpleasant 36. Bc4.

**35. gxf3 Bh4 36. Re2 f4 37. Bf2 **

It’s better for Black to agree to exchange the dark-squared
bishops, because after 37. Bg1 Rfg7 38. Bg2 Ng5 the activity of
black pieces can grow considerably.

**37... Bxf2 38. Rxf2 Nd4 39. Rd5 Rg5? **

39... Rg3 40. Bg2 Re7 41. c5 Kg7 was stronger, bringing the
king up to the c-pawn.

**40. Bd3 h5 **

40... Kg7 was preferable, because after 41. c5 Kf6 42. Rd6+
Ke7 43. Ra6 Kd8 Black held, though a mere 41. Be4 allowed White
to keep his advantage.

**41. h4 Rg3 42. Be4 Re7 43. c5 Kg7 44. Rg2 **

The active black rook should be exchanged.

**44... Rxg2+ 45. Kxg2 Kf6 46. Rd6+ Re6 **

After 46... Kg7 47. c6 Rc7 48. Rg6+ Kf7 49. Rh6 or 46... Kf7
47. Rh6 Black was doomed as well. But now it’s even simpler.

**47. c6!**

A simple but elegant blow.

**47... Nb5 **

After 47... Rxd6 48. c7 White’s pawn would have passed.

**48. Rd8 Re7 49. Rh8 Rg7+ 50. Kf1 Nd6 51. Rh6+ Ke7 52. Rxh5
Nxe4 53. Rxe5+ Kd6 54. Rxe4 Kxc6 55. Rxf4 **

Two extra pawns should be enough for White to win.

**55... Kd5 56. Re4 Rb7 57. Kf2 Rb2+ 58. Re2 Rb8 59. f4 Rh8
60. Kg3 Rg8+ 61. Kf3 Rh8 62. Re5+ Kd6 63. h5 Rg8 64. Ra5 1-0
Black resigned.**

**Ponomariov - Milov [B43]**

**1. e4 c5 2. Nf3 e6 3. Nc3 a6 4. d4 cxd4 5. Nxd4 b5 6. Bd3
Qb6 **

The Swiss grandmaster avoids the unhappy development which
took place in the first round after 6... Bb7 7. O-O Qb6 8. Be3
Bc5 9. Nce2 Nf6 10. b4! Bxd4 11. Bxd4 Qc7 12. c4! in the game
Svidler - Milov (Biel, 2000).

**7. Nf3 Qc7 8.0-0 Nc6 **

Previously only 8... d6 and 8... Bb7 were seen in this
position.

**9. Re1 d6 10. a4 b4 11. Na2 Nf6 12. Bd2 a5 13. c3 bxc3 14.
Nxc3 Be7 15. Nb5 Qb8 16. Bf4 e5 17. Rc1 Bd7 18. Bg5 O-O **

**19. Bc4 **

White became an obvious advantage from the opening.** **

**19... Nb4 20. b3 Bxb5 21. axb5 **

A strange decision. After a mere 21. Bxb5 White had a long
lasting advantage.

**21... Rd8 22. Qe2 Qb7 23. Bd2 Rd7 24. Bxb4 **

The move 24. Ng5 Black could have repulsed with 24... Bd8, but
there was no necessity to hurry with the exchange on b4. There
were ways to strengthen the position with 24. Bc3 or 24. h3.

**24... axb4 25. h3 Bd8 26. Nh2 h5 27. Nf3 g6 28. g4 hxg4 29.
hxg4 Ra3 30. g5 Nh5 31. Bd5 Qa7 32. Rc8 Nf4 33.Qe3 Qxe3 34. Rxe3
Nxd5 35. exd5 Kg7 36. Re4 Rxb3 37. Kg2 Bb6 **

The pawn on b5 should not be underestimated. In case of 37...
f5 38. gxf6+ Kxf6 39. Rb8 Kf5 40. Rc4 Rb2 41. b6 e4 42. Nd4+ Ke5
White won with 43. Rxd8! Rxd8 44. Nc6+ Kxd4 45. Nxd8 Kxc4 46. b7.

**38. Rb8 Ba7 39. Ra8 Bb6 40. Rb8 Ba7 **

If 40... Bd8, then after 41. b6 White’s pawn went up to the
transformation square very quickly.

**41. Ra8 Bb6 1/2-1/2 Draw.**
