Five Queens on the Board!

Arnaudov, Petar G (2442) - Moser, Eva (2436) [A80]
Max Gutmann Memorial, Augsburg (5) 2013

Notes by Boris Schipkov

1. d4 f5
The Dutch Defence.
2. Bg5 h6 3. Bh4 g5 4. e3








   
4...Nf6
White intends Qh5 checkmate.
5. Bg3 d6 6. h4 g4 7. Bd3 Nc6 8. Ne2 e5








   
9. Bb5
A novelty. The game Cuadrado Wentwort Hyde, G - Giulian, P ICCF email 2002 ended in a draw after 9. Nbc3 Bd7 (9...Qe7!?) 10. h5 Bg7 (10...a6) 11. Qd2 (11. Bh4) 11...Qe7 12. Bc4 Na5 13. Bd3 Nc6 14. Bc4 Na5 15. Bd3. Or 9. O-O Bg7 10. Nbc3 a6 (10...Bd7) 11. Bc4 Qe7 (11...Nh5!? and 11...Bd7!?) 12. Rb1 Bd7?! (12...Na5! is better, with counterplay) 13. b4, with a tiny edge in Hardfeldt, P - Stockhammar, P FICGS email 2010.
9...Qe7 10. c4
If 10. d5 then 10...a6 11.Ba4 b5, with equality. White could try 10. O-O.
10...Bd7
10...a6!? is interesting.
11. Nbc3








   
11...Bg7
More precise is 11...a6 12. Ba4 O-O-O 13. d5 Nb8, with counterplay.
12. d5 Nd8 13. Bxd7+ Qxd7 14. Qc2 O-O








   
15. e4?!
A dubious move. 15. Bh2!? is better, 15...Nf7 16. Ng3 f4 17. Nf5 Nh8 18. O-O-O Nh5 19. f3 g3 20. Nxg7 Kxg7 21. Bg1 Ng6 22. Kb1 Ne7 23. exf4 Nxf4 24. Be3 Nf5 25. Rde1, and White has a slight advantage.
15..f4 16. Bh2 Nh5
Stronger is 16...c6! 17. O-O-O Rc8.
17. O-O-O Nf7
17...f3!? is interesting, and White cannot open the diagonal g1-a7 for the bishop.
18. f3!
Now White can activate the dark-squared bishop.
18...g3 19. Bg1 Qe7 20. Kb1 Bf6 21. Nc1 Nh8








   
22. b4?!
Correct is 22. c5! dxc5 (22...Ng6 23. Nd3) 23. Na4 b6 24. Nxc5 Rfc8 (24...bxc5 25. Bxc5 Qd7 26. Bxf8 Rxf8 27. Nd3) 25. Na6, with a small edge to White.
22...Ng6 23. c5 Nxh4 24. Nb3
24. Nd3 deserves attention.
24...b6!
Planning to open the b-file to attack the white king.
25. Rc1 Ng7 26. Nb5 h5
Better is 26...bxc5! 27. bxc5 Rfb8, and Black has a small advantage.
27. a4 Qd7 28. Qe2 Rfc8 29. a5?
29. c6 is better, trying to make a draw.









   
29...bxc5!
Black opens the b-file and can attack the white king.
30. bxc5
Also hopeless is 30. Bxc5 Rcb8 31. Nxa7 dxc5 32. Nc6 Rxb4 33. Nxb4 Qa4!, winning.
30...a6?
Here Black can obtain a big advantage with 30...Rcb8! 31. c6 Qc8 32. Bxa7 Rxa7 33. Nxa7 Rxb3+ 34. Ka2 Qb8 35. Rb1 Rxb1 36. Rxb1 Qxa7 37. a6 Nxf3 38. gxf3 g2 39. Qxg2 Qxa6+ 40. Kb2 Bh4.
31. c6 Qe7 32. Na7?!
32. Nc3 is better, with counterchances.
32...Rcb8 33. Ka2 Rb4?!
33...Qf7!? is better.
34. Rxh4?!
White can play the strong 34. Ka3! Rbb8 35. Rc2, with counterplay.
34...Bxh4 35. Rc4
Or 35. Qxa6 Ne8 36. Ka3 Rbb8, and Black has a clear advantage.
35...Rbb8 36. Ra4








   
36...Bf6
The pawn chains are nice. Here Black can sacrifice the knight with 36...Ne6 37. dxe6 Qxe6 38. Qd3 Be7 39. Bb6 Bd8 40. Rc4 h4.
37. Qxa6 h4 38. Qb7
White sacrifices his queen. Possible is 38. Qf1!? Qf7 39. a6 h3 40. gxh3 Nf5 41. Nb5 Ne3, and Black is better.
38...Qf7
Worse is 38...Rxb7? 39. cxb7 Qe8 40. bxa8=Q Qxa8 41. a6, with equality.
39. a6








   
39...h3!
Eva Moser creates the passed pawns on the queenside.
40. gxh3 Qh5 41. Nb5 Ne8! 42. Nxc7 Nxc7 43. Qxc7 Qxf3 44. Bb6 Qg2+
Also good is 44...Qe2+ 45. Ka3 Qb5.
45. Ka3 Qxh3 46. a7 Re8 47. Qb7








   
47...f3
Black has a huge advantage thanks to the powerful passed pawns.
48. Bc7 f2 49. Bb8 f1=Q 50. Qxa8 g2 51. Qb7 g1=Q 52. a8=Q








   
52...Qc5+
An amazing position. Five queens on the board!
53. Qb4
Or 53. Ka2 Qc2+ (53...Qh2+ 54. Nd2 Qc2+ 55. Qb2 Qfb1+ 56. Nxb1 Qxb2#) 54. Ka3 Qa1+ 55. Kb4 Qhxb3+ 56. Ka5 Qaxa4#, checkmate.
53...Qa1#
White resigned. 0-1
