Sicilian Defence B90

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be3 e5 7. Nb3 Be6 8. h3 Be7 9. g4. For 9. f4 exf4 10. Bxf4 Nc6 11. Qe2 Nd7 12. 0-0-0 Nce5 see Navara – So, Prague 2015, match game 1. 9. ... d5 10. exd5 Nxd5 11. Bg2 Nxe3 12. Qxd8+ Bxd8 13. fxe3 Bh4+ 14. Kf1 Nc6 15. Nc5. “I decided to play this line of the Najdorf, because previously I had only used it in training games with Pentala Harikrishna”, then Navara said. 15. ... Bc4+ 16. Kg1 0-0-0 17. b3 Bg5 18. Re1 Bh4 19. Rb1 Bg5 20. Kf2. “I did not want to repeat moves, so I decided to advance my King. Analysis with the computer showed that White is not worse, although he does have to find some only moves”, Navara said. 20. ... Bh4+ 21. Kf3 e4+ 22. Kf4 g5+ 23. Kf5 Rhe8 24. Rhd1 Re5+ 25. Kf6. “Up to here was all preparation...”, Navara said. 25. ... Rg8. “During preparation, I joked that if the game ended in a quick draw, I would be disqualified for pre-arranging it, and if it was not drawm I’d be disqualified for following computer help ...”, Navara said. 26. bxc4 Rg6+ 27. Kxf7 Re7+ 28. Kf8 Rf6+ 29. Kg8 Rg6+ 30. Kh8!! “Who says ‘the Chinese Immortal’? No, it’s Navara – Wojtaszek that will remain in history of chess forever. Phenomenal!”, Grandmaster Andrey Deviatkin jubilated.


30. ... Rf6. If 30. ... Bg3? (with a direct threat of mate) then 31. Rd5! Be5+ 32. Rxe5 Nxe5 33. Rxb7! and White wins! 31. Rf1 Bf2 32. Rxf2 Rxf2 33. Rf1 Rxg2. Black should first have played 33. ... Re8+ and only then (after 34. Kxh7) 34. ... Rxg2 avoiding the Rook’s penetration. 34. Rf8+! Kc7 35. Nd5+. All chess engines quite rightly recommend 35. N5xe4(!), but it is understandable that Navara wants to win back the Exchange. 35. ... Kd6 36. Nxe7 Kxc5 37. Rf5+ Kxc4 38. Nxc6 bxc6 39. Rxg5 Rg3. “After 39. ... Rxc2 I did not see anything convincing at the board, although there are many ideas. Yesterday I had dinner with the Poles and pointed out that previously, I had only beaten Radoslaw twice, both in drawn Rook endings. So, that means today is the third...”, Navara said. Indeed 39. ... Rxc2 40. Kxh7 Kd3 looks like a draw. 40. h4 h6? A fatal faux pas. The artificial line 40. ... Rxe3 41. Kxh7 Rg3 42. h5 e3 43. h6 Kc3 44. Kg6 e2 45. h7 e1=Q 46. h8=Q+ Kxc2 would lead to a very drawish position. 41. Rg6 Rxe3 42. Kg7 Rg3 43. Kxh6 e3 44. Kg5? Navara relaxes in accuracy. After 44. g5 Rg4 45. h5 White’s two united passed Pawns apparently run faster than Black’s e-Pawn, e.g. 45. ... Re4 46. Rxc6+ Kd5 47. Rb6 Re6+ 48. Rxe6 Kxe6 49. g6 e2 50. g7 e1=Q 51. g8=Q+ and White should win. 44. ... Kd5? The decisive mistake. Correct was 44. ... Kc3! 45. Rxc6+ Kd2 46. Rd6+ Kxc2 47. Re6 Kd2 leading to a drawn game. 45. Kf4 Rh3 46. h5 c5 47. Rg5+! Kd4 48. Re5! 1 : 0. “After losing, Radek behaved impeccably and even took part in a post-mortem”, Navara said.

Radoslaw Wojtaszek – Fabiano Caruana
77th Tata Steel Chess Tournament; Rotterdam, January 15, 2015
Dutch Defence A88

1. d4 f5 2. c4 Nf6 3. g3 g6 4. Bg2 Bg7 5. Nf3 0-0 6. 0-0 d6 7. Nc3 c6 8. Re1 Na6 9. b3 Ne4 10. Bb2 Nxc3 11. Bxc3 Nc5 12. Ng5!? A novelty. The alternative 12. Nd2 d5 is roughly even, 赵雪 (Zhào Xuě) – M. Bartel, 41st Women’s Chess Olympiad, Tromsø 2014. 12. ... d5 13. Nh3 Ne4 14. Bb2 Be6 15. Nf4 Bf7 16. cxd5 cxd5 17. Nd3 a5 18. a4 b5!? Perhaps a little too ambitious. Black is willing to give up a Pawn of minor importance hoping to get up some sort of an attack on the Kingside. Worth considering was 18. ... Rc8 19. e3 Rc6 20. Rc1 Rxc1 21. Qxc1 Qb6 22. Qc2 Nd6 23. Rc1 Rc8 24. Qd1 Rxc1 25. Bxc1 with an edge for White (Monokroussos’ analysis). 19. axb5 Qb6 20. e3 Rfb8 21. Bf1 Qxb5 22. Ra3 Qe8 23. f3 Nd6 24. Qa1. Mounting pressure against the a5-Pawn. 24. ... g5 25. Bc3 g4 26. f4 Ne4 27. Bxa5 h5 28. Rc1 h4 29. Be1 Bf6 30. Nc5 hxg3 31. hxg3 Nxc5 32. Rxc5. White stands better; furthemore he is a Pawn ahead. With only 5 minites on the clock against opponent’s 45, Fabi skilfully finds a clever resource:


32. ... e5! 33. Rxa8!?? After long thought, Wojtaszek maximizes his practical chances of winning the game by playing a move which is not objectively the best one! The first choice of engines is 33. fxe5! Rxa3 34. Qxa3 Be7 35. Qb2! Bxc5 36. dxc5 with overwhelming compensation for the Exchange. 33. ... Rxa8 34. Qb1 exd4 35. Qxf5 Qxe3+? This move seems quite natural, but is actually inaccurate. After the less obvious 35. ... Qe6! 36. Qxe6 Bxe6 Black has good survival prospects. 36. Bf2 Qe6. Too late! 37. Bd3 Qxf5 38. Bxf5 Ra1+. Fabi found himself in time trouble and eventually it won the vertigo-dread of losing control. Here or on the next move Black should have played 38. ... Ra3. 39. Kg2 d3? 39. ... Ra3 was compulsory as the consequences of 40. b4 d3 are double-edged. 40. Bxd3 d4 41. b4 Bb3? A much cooler resistance results from 41. ... Ra4 42. b5 Rb4 seeking some chances of salvation. 42. b5+- Be7 43. Rh5 Rd1 44. Be2 Rd2 45. Bxg4 Rb2 46. Bf3 Bb4 47. b6! 1 : 0. For if 47. ... Be1 then 48. b7 Bf7 (48. ... Bxf2 loses to 49. b8=Q+ and 48. ... Rxf2+ fails to 49. Kg1 Rxf3 50. b8=Q+) 49. b8=Q+ Rxb8 50. Rg5+ Kf8 51. Bxe1 finis.

Hóu Yìfán had an excellent chance to take over solo second, but spoiled a winning position against Wojtaszek. Her 29. Qxc2 was very natural, eliminating a dangerous passed Pawn and consolidating her material advantage, but after a long series of exchanges her winning chances were minimal. Instead 29. Bxd5 Qxd5 30. Re8 (threatening 31. Qa4-a3!/Qa3-b4!) would have won. After 30. ... g5 (30. ... g6 31. Qa3! mates) 31. R8e5! (not 31. Qa3 this time, because after 31. ... Rxe8 32. Rxe8+ Kg7 33. Qf8 isn’t mate; here Black is even winning) 31. ... Qf3 (not 31. ... Bxe5?? 32. Ne7+) 32. Rc5 and now White will be two Pawns up, not just one, and will win.

侯逸凡 (Hóu Yìfán) – Radoslaw Wojtaszek
47th International Chess Festival “In Memoriam Hans Suri”; Biel/Bienne, July 21, 2014
Réti Opening A09

1. Nf3 d5 2. g3 c5 3. c4 d4 4. e3 Nc6 5. exd4 cxd4 6. Bg2 e5 7. 0-0 Nf6. For 7. ... Bd6 8. d3 Nge7 see Tomashevsky – Khalifman, 58th Russian Chess Championship, Moscow 2005. 8. d3 Nd7 9. Na3 Be7 10. Nc2 0-0 11. Rb1 a5 12. b3 Rb8 13. Re1 Re8 14. a3 Qc7 15. b4 axb4 16. axb4 b5


17. Nfxd4!! A deeply conceived sacrifice. 17. ... exd4. On 17. ... Nxd4 may follow 18. Nxd4 exd4 19. Bf4 Qd8 20. c5! and White has ample compensation for the sacrificed Knight. 18. Bf4 Nce5 19. Nxd4 bxc4 20. Nc6. The position has become much complicated as a result of White’s Knight sacrifice. Black has various ways of allowing her opponent to regain the piece, none of which seem to be good. 20. ... c3. A little too ambitious. Nolens volens, Black should play 20. ... Bxb4, although after 21. Rxb4 (or 21. Nxb4) 21. ... Rxb4 22. Nxb4 White keeps an edge. 21. Qa4. Possibly still winning, but now Miss 侯逸凡 (Hóu Yìfán) is starting to lose the thread. Probably stronger – and perhaps winning – was the computer move 21. d4, and also after 21. Rxe5 Nxe5 22. Bxe5 Bd6 23. Bxd6 Qxd6 24. Nxb8 Qxb8 25. Qc2 Qe5 26. Bc6 Re7 27. d4! Qxd4 28. Rd1 Qb6 29. Qxc3 h6 30. b5 White has much the better ending. 21. ... Rb6 22. Bxe5 Nxe5 23. Rxe5. Slowly but surely White – with an extra Pawn – has made progress. 23. ... Be6 24. Rbe1 Bf6 25. R5e3 Rf8 26. b5 Qd6 27. d4 c2 28. Be4 Bd5. Unsatisfactory, but what else to make it easier? 29. Qxc2. In serious time trouble, Miss 侯逸凡 (Hóu Yìfán) fears to play 29. Bxd5 Qxd5 30. Re5! (or 30. Re8 g5 31. R8e5!) 30. ... Qd7 (of course not 30. ... Bxe5?? because of 31. Ne7+, whilst 30. ... Qd6 31. R5e2 implies similar consequences to the text) 31. Rc5 with a huge advantage to White. 29. ... Bxe4 30. Rxe4 Rxb5 31. Re8 g6 32. Qc4 Qd5 33. Rxf8+ Kxf8 34. Rc1 Qxc4 35. Rxc4 h5 36. Kg2 Rb3 37. Nb4 Kg7 38. Nc2. I would have preferred 38. h4, since after 38. ... Bd8 39. Nc6 Bb6 40. Rc2 White’s extra Pawn is not so symbolic as in the game. 38. ... h4 39. Kf1 Rb1+ 40. Kg2 Rd1. Black is now safe. 41. Kf3 Rd2 42. h3 Rd3+ 43. Kg4 Rd2 44. Kf3 Rd3+ 45.
