Edwin David – Tore Langmyhr

Midtnorgeserien 08. februar 2020

Kommentert av GM Mihajlo Stojanovic

5… gxf6

1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Nxf6+

One of the sharpest lines in the entire Karo-Cann opening Black can choose.

6. Bc4

Natural square for the bishop but perhaps it can work better from another square.

6. c3 Bf5 7. Nf3 e6 8. g3 is considered to be optimal set-up for White. Here Rg8 is not dangerous any more and Nh4 might come. If Black goes with Be4 and f5 then Ng5 could be very dangerous like in next instructive game: 8… Bd6 9. Bg2 Be4 10. 0-0 Nd7 11. Re1 f5 12. Ng5! Bxg2 (12… Bd5 13. Qh5 Qe7 14. Bxd5 cxd5 15. Rxe6+-) 13. Qh5! 1-0 in Wells,P (2490)-Nestorovic,V (2290) Harkany 1994

6… Bf5 7. Ne2 e6 8. Ng3 Bg6 9. h4 h5

10. Ne2

The knight looks excellent on f4, attacking both Bg6 and pawn h5 but this maneuver costs two moves.

White holds small but stable advantage with 10. c3 Bd6 11. Qf3 Nd7 12. Bf4 Bxf4 13. Qxf4 Qb6 14. 0-0-0 0-0-0

10… Bd6 11. Nf4

11… Bf5

11… Be4! saves pawn h5 because pawn g2 hangs as well. If 12. 0-0?! Nd7 13. Nxh5?! f5 Black`s attack worths more than a pawn.

12. Be3

White could immediately take 12. Nxh5 because if 12… Bxc2 13. Ng7+ Kf8 14. Nxe6+

12… Nd7 13. Nxh5

13… Rg8

Threatening Bg4

14. Nf4

14… Qc7

Really strong is 14… Qb6! It attacks pawn b2, threat is Qb4+ so to take Bc4 as well… and keeps option for Bxf4 and then Rxg2

15. Qd2 0-0-0 16. 0-0-0

16… Nb6

Perhaps the key moment of the game: where to go with the bishop?

17. Bf1

The most principled move – here bishop protects the pawn.

But trouble is that Black gets too much counter play 17. Bd3 Bxd3 18. Nxd3 Rxg2 does not look very promising for White 19. Qe2 f5

It was really difficult to spot that after 17. Bb3 Bxf4 (17… e5 18. Qa5!? motive easy to miss during the game) 18. Bxf4 e5 19. Be3 (19. Bg3 c5!) 19… Rxg2 (19… c5 20. Qa5 Again, so if cxd4 21 Bxd4) 20. Qe1! White has better position (20. Qe2 Bg4)

17… e5

Even stronger is 17… c5 because bad is 18. dxc5? Bxf4 19. cxb6 (19. Bxf4 Rxd2 20. Bxc7 Rxc2+ wins) 19… Rxd2 20. bxc7 Rxc2+ 21. Kb1 Rxf2+ with victory.

18. Nh5

18. Qa5!

18… exd4

19. Bh6

19. Bxd4 Bg4

19… Rh8

No good is 19… Bg4 20. Nxf6

20. Be2 Bg6

21. Kb1

Moving from Bf4 in case. Of course not 21. Nxf6?? Rxh6-+

21… Nd5

Fine bringing the piece closer to the opponent king.

The engine gives 21… d3! 22. cxd3 Nc4 23. Qc1 Nxb2 24. Qxb2 Rxh6 Black has clear advantage regarding the exposed White`s king.

22. Ng3

22… Rxh6!?

Attractive distraction (although White still can hold the position) of the queen from task of defending the king.

Direct 22… Qb6 23. Ka1 Nb4! works excellent, for example 24. Bd3 Rxh6! 25. Qxh6 Qa5 26. a3 Nxd3 27. cxd3 Bxa3! 28. bxa3 Qxa3+ 29. Kb1 Rd5 creates a mating net.

23. Qxh6 Bf4 24. Qg7 Qb6

25. Ka1

Amazing that after 25. Bd3 Nc3+ 26. Ka1 Qa5 (26… Nxd1 27. Rxd1 is worse for Black) 27. bxc3 Qxc3+ 28. Kb1 Qb4+ it is perpetual check on the board… such a big chess fight could finish peaceful!

25… Bxc2

26. Qxf7

White`s chance to save the game was 26. Bd3! Bxd1 (26… Bxd3!? 27. Rxd3 c5 is also very interesting) 27. Rxd1 with objectively better position for Black but with a quite demanding task of proving it.

26… d3 27. Bg4+ Kb8 28. Rde1 d2

29. Re8

If White can play Qd7 now (threatening Qc8 too) that will be victory for him. Unfortunately, no time for that move.

29… Be5!

30. Rxe5

After 30. Rxd8+ Qxd8 31. h5 Qa5!

(In the game of chess one mistake can ruin everything: 31… Qb6?? 32. Qe8+ Kc7 33. Qd7+ Kb8 34. Qc8#)

32. Qe8+ Kc7 33. Qc8+ Kb6 34. Qd8+ Nc7 it is not possible to prevent well Black`s threat Qc3!!

30… fxe5 31. h5

31… Qd4

Pawn d2 is ready to promote.

32. Nf5

If 32. Bd1 Bxd1 33. Rxd1 Qc4-+

32… Bxf5 33. Qxf5

33… Nb4!

Promotion of the queen is threat again.

34. Rd1

34… Qc4!

Finishing the attack in style.

35. b3

Does not helt 35. Qxe5+ Ka8

35… Qc1+ 36. Qb1 Nc2#

0 – 1
