Why the best men in chess are stronger than the best women?

Carlsen, Magnus (2837) - Polgar, Judit (2673) [E81]
World Blitz Chess Championship, Dubai (14) 2014

Notes by Boris Schipkov

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3
The King's Indian Saemisch System.
5...O-O 6. Be3 a6 7. Nge2 c6








   
8. a4
A rare move. The most aggressive alternative is 8.g4 to attack on the kingside.
8...a5 9. Ng3 Na6 10. Be2








   
10...Qc7
A novelty. In the game Rumjantsev, J - De Filomeno, S, Kemer 2009, Black played 10...Nb4 11. O-O e5 12. d5 (12. Qd2!?) 12...cxd5 (12...Nd7) 13. cxd5 h5 14. Na2?! (14. Nh1!?, with a small edge to White) 14...Nxa2 15. Rxa2 h4 16. Nh1 Nh5 17. Nf2 Nf4, with good counterplay.
11. O-O e5 12. d5 h5?!
Black can play on the queenside with 12...Nd7!?.
13. Qd2 h4 14. Nh1 Nh5 15. Nf2








   
15...f5?!
After 15...Nf4 16. Rfd1 Nc5 17. Ra3 White has a small advantage.
16. Nd3
16. exf5!? is interesting, 16...gxf5 17. Bg5 Nc5 18. Bd1 Bf6 19. Bc2, with a small edge to White thanks to Black's weaknesses on the king's wing. Also possible is 16. Bg5 Nf4 17. Bd1 (17. Bxh4? Bh6 18. Kh1 g5 19. g3 gxh4 20. gxf4 Bxf4 21. Qe1=) 17...Nb4.
16...f4 17. Bf2 Ng3!
Judit Polgar finds nice tactical ideas.
18. Rfd1
If White takes the knight at once Black has a good game and can attack the white king: 18. hxg3 hxg3 19. Rfd1 (19. Be1? Bf6! 20. Nf2 Qh7) 19...gxf2+ 20. Kxf2 Qxb6 21. Kf1 Rd8.









   
18...c5?!
18...Nxe2+ is better, 19. Qxe2 h3 20. c5 hxg2 (20...dxc5 21. Nxc5 Nxc5 22. Bxc5 Re8 23. Rac1) 21. cxd6 Qxd6 22. Kxg2 g5, with counterplay.
19. hxg3 hxg3 20. Bxg3!
Simple and strong. The greedy 20. Be1? is worse, 20...Bf6 21. Kf1 Qh7 22. Bf2 gxf2 23. Nxf2 Nb4, and Black is better.
20...fxg3 21. Qg5 Qf7








   
22. Nb5
22. Qxg3 is more precise, 22...Bh6 23. Kf2 Kg7 24. Rh1 Rh8 25. Rh4 Qf6 (25...Bd7 26. Rah1 Qf6 27. Qh2 g5 28. Rh5) 26. Rah1, with a small edge to White.
22...Qf6 23. Qxg3 Bh6!
Black activates the dark-squared bishop.









   
24. Kf2
Here 24. Qf2!? deserves attention, 24...Bd7 25. g3 Nb4 26. Nxb4 axb4 27. b3 Rf7 28. Kg2 g5 29. Rh1 g4 30. Raf1 Raf8 31. Qe1 Qg6 32. Nc7 Rg7 33. Ne6 Bxe6 34. dxe6 gxf3+ 35. Bxf3 Qxe6.
24...Nb4?
A mistake. 24...Kg7! is better, 25. Rh1 Rh8 26. Rh4 (26. Nxd6 Qxd6 27. Qxe5+ Qxe5 28. Nxe5 Nb4 29. f4 Nc2 30. Raf1 Re8 31. g3 Rxe5 32. fxe5 Be3+ 33. Kf3 Bd4 34. e6 Ne3 35. Kf4 Nxf1 36. Rxf1 Bxe6) 26...Bd7 27. Nxd6! Nb4! 28. Nf5+ (28. Nxe5 Bg5=) 28...Bxf5 29. exf5 Qxh4 30. Qxh4 Be3+ 31. Kxe3 Rxh4 32. Nxb4 axb4 33. fxg6 Kxg6 34. g4 Kf7, with equality.
25. Rh1 Kg7 26. Qh4
White can sacrifice the exchange and get a clear advantage after 26. Rxh6! Nxd3+ 27. Bxd3 Kxh6 28. Rh1+ Kg7 29. Qh2 Kf7 30. Qh7+ Qg7 31. Nxd6+ Kf6 32. Rh4 Qxh7 33. Rxh7 Rb8 34. g3 g5 35. Ke3.









   
26...Qxh4+?
Correct is 26...g5 27. Qg3, with a small edge to White.
27. Rxh4 Bg5
Or 27... Rh8 28. Nxb4 axb4 29. Rah1 Ra6 30. b3 Bd7 31. g4 g5 32. R4h2 Kg6 33. Rh5 Kg7 34. Bd3 Kg6 35. Nc7, and White wins.
28. Rh2








   
28...Be3+?!
If 28...Rd8 then Magnus Carlsen attacks on the h-file with 29. Rah1 Bf6 30. Rh7+ Kg8 31. Nxb4 axb4 32. Rc7, winning.
29. Kxe3 Nc2+ 30. Kd2 Nxa1 31. Kc3
White wins, because the black knight cannot escape, and two pieces are better than one rook.
31...Ra6 32. Rh1 Bd7 33. Rxa1 Bxb5 34. cxb5 Raa8 35. b3 Rh8








   
36. b6
Also possible is 36. f4 exf4 37. Nxf4 b6 38. Rf1, winning.
36...Rh2 37. Rg1 Ra6 38. Nb2 Rxb6 39. Bb5
And White takes the rook after Nc4.
Why the best men in chess are stronger than the best women? Why in the Standard Top 100 Players in the FIDE rating list is only 1 woman, and in the Blitz Top 100 Players May 2014 in the FIDE rating list are 3 women? I know the truth. The main reason of the male predominance in chess and other games are different reactions of men and women to the physiological stress. Men have the better stress tolerance than women. Also in the stress situations in the brain of a man the cerebral cortex is activated to make a decision, in the brain of a woman the limbic system is activated to find a help from other people. Therefore in chess in the situations when a rival uses a novelty, or in the complex, new positions a woman makes more mistakes than a man.
Black resigned. 1-0
