Questions and Answers
Question: What is PGN?
Answer: The PGN format (Portable Game Notation) is an international standard for saving games as ASCII text. Many chess programs support this format.
Question: Why the best men in chess are stronger than the best women?
Answer: 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.

Question: Bishop or Knight: Which is better?
Answer: Bishop is somewhat better than Knight, if we consider all positions. In the closed positions Knight is better, in the open positions Bishop is better. Frequently in the endgames Bishop is better than Knight. Knight and Queen are stronger in an attack on King than Bishop and Queen. Also I think that in blitz chess Knight is slightly more dangerous than Bishop thanks to unexpected manoeuvres and forks.

Question: The Lasker-Pelikan after 7.Nd5 NxN 8.exd5 Nb8 which I use to play until a friend showed
me 9.Qf3 with the idea of 10.Qa3 and if necessary Bd2 and later Bb4. It looks silly
but black hasn't any clear way out (Dominique from France).
Answer: The last answer - My new article (19th April 2015) The Sicilian Defence B33, Variation 7.Nd5 Nxd5 8.exd5 Nb8 9.Qf3.
I think 9.Qf3 and 10.Qa3 is a slow manoeuvre. And f3 (or a3) is not good place for the queen. Let's see
1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Nd5 Nxd5 8. exd5 Nb8 9. Qf3 a6 10. Qa3 b6 11. Bd2?!
Better is 11. c4 Bb7 12. Nc3 Be7 13. Bd3 O-O 14. O-O Nd7 with equality.
11...Bb7 12. Nc3 Be7 13. O-O-O O-O 14. Kb1 Qc7 15. Be3 Rc8 16. h4 Nd7 17. Bd3 b5
with attack in Trkulja, G - Rajkovic, D, Zlatibor 1989 (0-1, 60).
Also possible is 9... a6 10. Qa3 Be7 11. Bd2 O-O 12. Bb4
12...Bg4 13. Bxd6 axb5 14. Bxe7 Qxd5 15. Qxa8 Qe4+ 16. Kd2 Qf4+ 17. Ke1 Qe4+ 18. Kd2 Qf4+ 19. Ke1 Qe4+ 20. Kd2 1/2-1/2, draw in Guyot, Ph - Popchev, M, Podgorica 1991.
Interesting is 12... axb5! 13. Qxa8 Na6 14. Bd2 Qc7 15. c3 Qc5 16. Be3 Qxd5 17. Qa7 f5 18. Rd1 Qe4 with good compensation for the exchange (June 2001).
