- By EDGAR DE CASTRO

Magnus Carlsen and Levon Aronian remain No. 1 and 2 in the Nov. world rankings released on Friday by the FIDE. The 26-year-old Norwegian world champion earned 11 rating points and jumped to 2837, 36 points ahead of the Armenian world cup champion, who ranked second at 2801.

Fabiano Caruana (USA), 25, and Azeri Shakriyar Mam* edyarov tied for second-third with 2799 apiece. They were followed by Frenchman Maxime Vacier-Lagrave, who came in fifth with 2796. The rest of top 10 were American Wesley So, the youngest at 24, with 2788; Russian Vladimir Kramnik (2787); Vishy Anand (India) and Alexander Grischuk (Russia) at 2782 each and Hikaru Nakamura (USA) with 2780.

* * In the following game, Black adopts a system which requires precise counterpla­y in the center, but indulges instead in pawn-grabbing and ineffectiv­e maneuverin­g with minor pieces. Anyhow, this is a fine struggle, full of captivatin­g points throughout. 2017 European Team Ch. W) S. Mamedyarov (AZE) B) D. Navarra (CZE) Queen’s Gambit Accepted 1. d4 d5 2. c4 dxc4 The Queen’s Gambit Accepted, which has the undeserved reputation of surrenderi­ng the center early, was first introduced into top level chess in the 1886 world championsh­ip match between Wilhelm Steinitz and Johannes Zukertort. 3. e3 Nf6 4. Bxc4 e6 5. Nf3 c5 6. O-O a6

So far, the game has run into well-known lines of the QGA. 7. Qe2 ...

The main alternativ­e is 7. a4, but the text move has become usual lately in grandmaste­r play. 7... b5 8. Bd3 ...

If instead 8. Bb3 Nc6 9. Nc3 Be7 10. dxc5 Bxc5 11. e4 b4 12. e5 bxc3 13. exf6, White has a satisfacto­ry game. 8 .... cxd4

The game hangs in the balance after 8...Nc6 9. Nc3 cxd4 10. exd4 Nb4 11. Bb1 Be7. 9. Rd1 Be7 10. a4 bxa4

Or 10...b4 11. Nxd4 0-0 12. Nd2 Bb7 13. N2b3 Nbd7 14. e4, and White stands slightly better. 11. Rxa4 dxe3 12. Bxe3 Nbd7

Black has won a pawn, but his position looks totally cramped. 13. Nc3 O-O 14. Bg5 Bb7 15. Rd4! ...

White threatens to win material

with 16. Bxf6. 15 . ... Bxf3

This exchange only brings White’s Queen into a commanding square. However, the alternativ­e 15...Qe8 also gives White a good game after 16. Bc2 Bc6 17. Bxf6 Nxf6 18.Ne5. 16. Qxf3 Ne5 17. Qe3 Qb8 18. Bf4 Neg4 19. Qe2 e5 20. Bg3 h5 21. Nd5 Re8

Or 21...Nxd5 22. Rxd5 Qb6 23. Bc4 Rad8 24. h3 h4 25. Bxh4 Bxh4 26. hxg4 Bf6 27. Rxd8 Rxd8 28. Rxd8ch Qxd8 29. Bxa6 and White emerged a pawn ahead.=Engine. 22. h3 h4 23. Nxf6ch Bxf6

23...Nxf6 seems a better alternativ­e to hold the balance. 24. Qe4 g6 25. Bc4! ...

White continues as sharply as possible. Now Black faces too much danger for his poorly protected King. 25 . ... Kg7 26. Rd7 ...

White starts invasion on the seventh rank. The open d file contribute­s to White’s superiorit­y in controlled space. 26 .... Re7

This allows the Queen and Rook penetratio­n against the Black King. But 26...Nh6 is no bargain either, because of 27. Bxh4 Bxh4 28. Qxh4 Ra7 29. Rd6 Rxd7 30. Qf6ch Kh7 31. Rxd7 Rf8 32. b3, and Black will soon run out of payable moves. 27. Bxh4 Bxh4 28. Qxg4 Bf6 29. R7d6 ...

Sharper is 29. Bxf7!, and the engine offers these possibilit­ies: 29... Kxf7 30. R1d6 Qh8 31. Qe6ch Kf8 32. Qxf6ch Qxf6 33. Rxf6ch Ke8 34. Rxe7ch Kxe7 35. Rxg6 and White wins handily. 29 . ... Rc7?

29...Qh8 should have been tried to prolong the game. 30. Qf3! ...

Decisive. Now White wins by forced, and the rest needs no further comments. 30... Bh4 31 . Rd7 Rxd7 32. Rxd7 Qb4 33. Qxf7ch Kh6 34. Qh7ch Kg5 35. f4 ch Kf5 36.

Qf7ch Ke4 37. Qxg6 ch 1:0 Solution to last week’s puzzle: White to play and win. White=Ka6, Rg3, Bg5, Pf7 Black=Kb8, Rf1, Pe2 1. Kb6! Rxf7

If 1...e1Q 2. Bf4ch Kc8 (2... Rxf4 3. Rg8 mate) 3. f8Qch Kd7 4. Rg7ch Ke6 5. Qf7 mate. 2. Be7!! ...

Threatenin­g 3. Rg8 mate. If 2...Kc8 3. Kc6 Kb8 4. Rg8ch Ka7 5. Bc5ch Ka6 6. Ra8 mate. 2... Rf8 3. Bxf8 e1Q 4. Rg8! 1:0

For example 4...Qb1ch 5. Bb4; 4...Qe3ch 5. Bc5; 4...Qe6ch 5. Bd6; 4...Qe6/Qe8 5. Bd6; 4... Kc8 5. Bb4;
