Peake GM v Kev-Blitz Match

Game 20

White      Black

Kev-Blitz  - GMP

0:1 (ICC 10 15 u)  6/11/2003

 

1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. cd Nxd5

I came across this when conducting opening preparations. I was quite surprised that it seems playable. The lines are very similar to the Grunfield in that Black has the thematic c5 counter against the White centre (unlike the Marshall) . It is also similar to the QGA. Black also has an ominous endgame advantage with his 2 to one on the Q-side. He has White's d-pawn restricted with e6, but does not have the black squared bishop fianchettoed. This is often exchanged by Bb4 check. I have tried it three times on the ICC ...the third time was against Kev.

5. e4 Nxc3

6. bc c5

7. Nf3 cd

8. cd Nc6

 Well Bb4 check exchanging pieces is a popular way of playing this, but there is no rush for me.

9. a3 Yes now White has in fact lost a move preventing the check. This  has been played 31 out of 228 times, but too slow for me. Why is White scared of Bb4 + ? Kev tends to over-elaborate with positional prophylaxis - type moves occasionally

[If 9. Bc4 b5   trick is available.]

9... Be7

10. g3  Novelty  ? This has never been played and is a bad idea. Kev is unfamiliar with this line and it is starting to show.

[10. Bd3 O-O 11. Bb2 Qa5 12. Kf1 Rd8 13. Qe2 Bd7 14. Rd1 Be8 15. h4 Qh5 16. Rh3 Bf8 17. Rg3 h6 18. d5 ed 19. ed Ne7

...1-0, Lipinsky Fabian 2390  - Kovacs Attila 2365 , Szeged 1998 It]

10... O-O

11. Bg2

[11. Rb1!? Qa5 12. Qd2 Qxd2 13. Kxd2 allows Queens to be swapped.]

11... Qa5 Black is keen for the Queen swap to reach a better ending. 

12. Bd2 Qa6 This looks artificial - but Black prevents White castling - Qe2 would swap Queens, Rb1 drops the a pawn so....

13. Bf1

[13. Bc3!? Bd7 14. Bf1 Qb6 15. Bc4]

13... Qb6 White's a and d pawns are under annoying pressure.

14. Rb1

[14. Bc3 Qc7 15. Qd2 Rd8 and b6 would be the best continuation.³]

14... Qd8 The point of Black's play ! - the d-pawn and a-pawn are threatened.

15. Bc1 White appears to have gone backwards to where he was on move ten. Qa5 Now Black forces the Queen swap.

16. Qd2 Qxd2

17. Kxd2 f5 An important blow against the White centre. White is still under pressure.

18. e5

[18. ef Rxf5 Black has good play.]

18... Rd8

19. Bb2 g5 Every move a threat is a great way to play chess if you can do it !!

20. Ke3?!

[20. h3 looks forced. h5 21. Bb5 g4 22. Bxc6 bc 23. hg hg followed by c5 puts White in difficulties.]

20... g4

21. Nd2?

 -1.61 Tiger 15.0

[21. Ng1 ! was best - though it looks awful. b6 22. Ne2 Bb7 23. Bg2 Bg5 24. Nf4 Rab8 threatening Nxe5 keeps Black better.]

21... Bg5

22. Ke2 Nxd4 Black's strategy has succeeded and he mops up a pawn.

23. Bxd4 Rxd4

24. Rb2?!

 -2.26 Tiger 15.0

[24. f4 appears best gf 25. Nxf3 Re4 26. Kf2 Be3µ]

24... b6

25. Bg2?!

 -6.01 Tiger 15.0

[25. f4! Bb7 26. Rg1 Be7 27. Nb3 Re4°]

25... Ba6 Now White is losing material - It's a nightmare for him.

26. Ke1 Rad8 It's great when every one of your pieces is doing a job, combining  together !

27. Nb3 Rd1#

White checkmated
