|El ex campeón del mundo está demostrando en Shamkir que todavía tiene mucho para dar. Si bien la máquina Carlsen tiene las mejores probabiblidades de ganar el torneo, el indio, que parece tener seguro el segundo puesto, es quien le ha aportado belleza a la competición. Primero ejecutó una novedad de apertura, ¡en la centenaria Ruy López!, contra So, quien no pudo encontrar sobre el tablero la mejor defensa contra la innovación. Pero lo mejor estaba por llegar. Sendos sacrificios de calidad contra Adams y Mamedyarov, lo pusieron a sólo medio punto del campeón del mundo.

1. c4 These days the top players try to mainly surprise their opponents in the opening and to avoid the heavy home preparation. They also try to get some psychological advantage . This approach is quite unpleasant against a player who is not doing well in the opening. Anand chooses the English opening which he only played three times before in classical games - one being against Adams, by the way.
1... e5 2. g3 (2. Nc3 Nf6 3. Nf3 Nc6 4. g3 g6 5. d4 exd4 6. Nxd4 Bg7 7. Bg2 O-O Anand,V (2775)-Adams,M (2710) London 2012 )2... c6 Adams also replies with a surprise in return. He had used the reversed Alapin in 2008 and for Anand this is already new.
3. Nf3 (That only game of the Englishman went 3. d4 Bb4+ 4. Bd2 Bxd2+ 5. Qxd2 d6 6. Nc3 Nf6 7. Bg2 O-O 8. e3 Nbd7 Miezis,N (2540)-Adams,M (2735) Liverpool 2008 )3... e4 4. Nd4 d5 5. cxd5 Qxd5 6. Nc2 Nf6 7. Nc3 Qh5 8. Ne3 This position is already very fresh. It was played only once in an over-the-board game. White prepares to pressurize the exposed e4-pawn and opens the road for the queen.
(The complications arising after 8. d3 exd3 9. Qxd3 Na6 10. Bg2 Bh3!? 11. Bf3 Qg6 12. Bxc6+ bxc6 13. Qxa6 Rd8 are not everyone's cup of tea, Svidler,P (2753)-Topalov,V (2772) Flor & Fjaere 2014 )(8. h3 is another move. )8... Bc5 A solid reaction. In case of
(8... Bh3 9. Qb3! b5 10. Qc2 Bxf1 11. Rxf1 Qe5 12. f3 exf3 13. Rxf3 Black's position has too many loose ends, Berkes,F (2606)-Borisek,J (2508) Heraklio 2007 )(8... Na6!? deserves attention in order to torture the queen anytime it comes to c2. )9. Qc2 Bxe3 (Or else Black loses the pawn 9... O-O 10. Nxe4 )10. fxe3 Anand wants to use the half-open file to possibly lift the rook to f4 and increase the pressure on e4. And for something more...
10... Qe5 11. Bg2 Bf5 12. O-O O-O 13. b3 The novelty.
(A correspondence game went 13. b4 Nbd7 14. Bb2 Qe6 15. b5 Rac8 16. Qb3 Rfd8 17. Rac1 Nc5 18. Qxe6 Bxe6 19. Rc2 Bd7 20. bxc6 Bxc6 and Black managed to solve the problem of the e4 pawn, Littke,H (2254)-Kolek,P (2399), 2011 )13... Nbd7 14. Bb2 Qe6 One more move and Adams will cement his position for good with Bf5-g6. But...
15. Rxf5! A nice positional sacrifice of the exchange. White wins the central pawn for it and the bishop pair. It is interesting that both players did not evaluate the position similarly. Adams considered it perfectly OK, while Anand thought it is easier to play as White.
15... Qxf5 16. Nxe4 Qg6! The best defense. Else White will point his bishops towards the kingside with
(16... Nxe4 17. Bxe4 Qh5 18. Rf1 followed by Rf4-h4 and attack (Anand). )17. Rf1 Rfe8 18. Bxf6 Tit for tat. White destroys the pawn structure in front of the enemy king.
18... Nxf6 19. Nxf6+ gxf6 20. e4 Rad8 21. Rf4 Anand's plan is to bring the bishop to f5, play d2-d3, bring the rook to h4 and attack the kingside with Qd2-h6.
21... Qh5! Adams hurries to escape from the danger zone.
22. d3 Qe5 23. Bh3 Kg7 24. Kg2 h5!? An interesting pawn sacrifice. Black manages to temporary exclude the rook from the game.
(Something solid like 24... Rh8 was also possible. )25. Rf5 Qd4 26. Rxh5 Qe3 27. Rh4 (One point behind the pawn sacrifice is demonstrated by Anand. The rook cannot come back at once 27. Rf5? Rxe4! works well for Black with the idea 28. dxe4 Rd2 29. Qc4 b5 30. Qc5 Rxe2+ 31. Kh1 Re1+ 32. Bf1 Rxf1+ 33. Kg2 Rf2+ 34. Kh3 Qh6+ and Black wins. )27... Re5 28. Rf4 White's chances are connected with the kingside attack and for this reason he should not allow any trades of the heavy pieces.
(Another problem is revealed by the line 28. Bf5 Rh8! 29. Rf4? (Black would be happy to trade the rooks and kill the attacking potential of his opponent 29. Rxh8 Kxh8 when only Black can play for the win. )29... Rc5 30. Qb2 Rc1 and wins. )28... Rc5 29. Qb2 Rd6 30. Rf1 a5 Adams placed his pieces in a very good way and now improves the mobile pawns.
31. Bf5 b5 32. h4 (Anand also considered the pawn sacrifice 32. b4 axb4 33. Rf3 Qd4 34. Qd2 in order to return to his original idea of kingside attack, but at the end decided that it was too risky. )32... Rd8? "The decisive blunder" (Anand) "Awful move" (Adams). The English GM missed a nice tactical regroupment. Instead many moves lead to dinamic equality:
(32... b4 )(32... a4!? In both case White cannot effectively use his queen in the attack due to the weakness of the b3 and e2 pawns. )(They also considered 32... Qd4 good for Black, but this is questionable as it allows the white queen a kingside sortie 33. Qd2 Rd8 34. h5 and White is definitely better. )33. a3 b4 34. axb4 axb4 35. Be6! The bishop is transferred to the optimal c4 square from where it cements the queenside while attacking the f7 pawn. Black's position immediately becomes bad.
35... Rc3 (The bishop is full of poison: 35... fxe6 36. Qxf6+ is mate in seven. )(Noweven the endgame is lost for Black as Anand explained 35... Qd4 36. Qxd4 Rxd4 37. Bc4 followed by g3-g4, Kg2-f3-e3, and later g4-g5 which will win the pawn on f7. )36. Bc4 White cemented the position and can get rid of the opponent's queen easily. After that his queen comes into the game and the step-by-step attack is unstoppable.
36... Ra8 37. Rf5 Ra7 38. Rf3 Qc5 (38... Qh6!? was more stubborn. )39. Qd2 Qd6 40. Qe3 The former world champion is not in a hurry.
(40. Rf5 with the threat Rf5-h5 was faster as if 40... Ra8 41. e5! destroys the barricades. )40... Ra5 41. Rf2 Rc2 42. g4 Qd7 43. Qg3 Rc5 44. g5! The decisive break. It is again the Bc4 to blame for Black's misery.
(44. e5 would also do. )44... fxg5 45. Rxf7+ Qxf7 46. Bxf7 Kxf7 47. Qf3+ Kg7 48. h5 The rest is easy for Anand.
48... Ra5 49. Kf2 Rb2 50. h6+ Kg6 51. h7 An inspired and interesting battle!
(Black resigned as he loses the rook: 51. h7 Kxh7 52. Qf7+ Kh6 (52... Kh8

1. e4 e5 2. Nf3 Nf6 Mamedyarov has been very successful in his last six games in the Petroff: 5.5/6! Who dares claiming that the opening can be boring after that?
3. Nc3 Surprise! Anand has played the Four Knights back in 1992-96 via a different move order though.. .
3... Nc6 4. Bb5 Bb4 (Ruinstein's recipe is sharper and more forceful. Ivanchuk has used it twice against the Indian: 4... Nd4 5. Ba4 Bc5 6. Nxe5 O-O 7. Nd3 Bb6 8. e5 Ne8 9. Nd5 d6 with compensation for the pawn, Anand,V (2715) -Ivanchuk,V (2700) Monte Carlo 1995 )5. O-O O-O 6. d3 d6 7. Ne2!? (7. Bg5 )7... Ne7 8. c3 Ba5 9. Ng3 Ng6 Funnily enough, the position now is similar to some lines of the Ruy Lopez. Yep, the Berlin ones.
(Anand said that his second had shown him the following game played earlier this week at the World Teams: 9... c6 10. Ba4 Ng6 11. d4 Re8 12. Bc2 h6 13. h3 Be6 14. Re1 Bc7 15. Be3 d5 16. Nxe5 Nxe5 17. dxe5 Nxe4 18. Nxe4 dxe4 19. Bd4 Bd5 20. Bxe4 c5 21. Bxc5 Rxe5 22. Bxd5 Rxd5 23. Bd4 Qd6 24. Qg4 Rg5 25. Qf3 Qh2+ 26. Kf1 Qh1+ 27. Ke2 Qxg2 28. Qxg2 Rxg2 29. Kf3 Rh2 30. Re7 Rxh3+ 31. Kg4 Bd6 32. Rd7 Rd3 33. Rxd6 Re8 34. Rg1 g6 35. Rg3 Rd2 36. Re3 Rf8 37. Re7 1-0 (37) Wei,Y (2706) -Melkumyan,H (2676) Tsaghkadzor ARM 2015 )10. d4 Bb6 11. Re1 c6 12. Bd3 Re8 13. h3 h6 14. Be3 Be6 Both sides developed their pieces harmoniously and naturally.
15. Qc2 (Also possible is the development of the queen on the c1-h6 diagonal. 15. Qd2 Qc7 16. Nf5 Bxf5 17. exf5 Nf8 And now the typical Italian sacrifice with 18. Bxh6? does not work because of the cool 18... N8h7! (not because of 18... gxh6 19. Qxh6 Qe7 20. dxe5 dxe5 21. Nxe5 and White should be winning )19. g4 e4 20. g5 Nh5 21. Bxe4 gxh6 with advantage for Black, Adhiban,B (2481)-L'Ami,E (2593) Dieren 2009 )15... Qc7 16. a3 A novelty. White wants to expand on the queenside.
(A predecessor saw 16. c4 exd4 17. Nxd4 Ne5 18. Be2 Ng6 19. Rad1 1-0 (43) Nguyen,A (2496)-Markus,R (2436) Budapest 2000 )16... a5 17. c4 a4 It is not quite clear why the inserted moves a2-a3 and a5-a4 should favour White. More likely they should favour Mamedyarov.
18. Red1 Anand moves the rook away from a possible tempo on a5.
(However, the line after 18. Rad1 exd4 19. Bxd4 Ba5?! leads to favorable complications for White after 20. Bxf6! Bxe1 21. Nh5 )18... exd4 Because of the annoying threat of c4-c5 Black should do this sooner or later. Now the pawn structure modifies to one which is similar to some lines of the Bogoljubow defense.
19. Bxd4 (Black is OK after 19. Nxd4 Bd7 20. Ndf5 Bxe3 21. Nxe3 Nf4 )19... Ne5 20. Be2 Mamedyarov more or less solved the opening problems. If Anand has any advantage it is symbolic.
20... Bc5 (Instead, one good away to exploit the hole on b3 was 20... Bxd4!? 21. Nxd4 Ned7 followed by Nd7-c5-b3 with equality. (But not 21... Nfd7? 22. f4 ))21. Rd2 Nfd7 22. Rad1 Red8?! Up to now Mamedyarov defended flawlessly, but this move is a mistake. In a cramped position it is always good to trade some pieces.
(22... Nxf3+ was mandatory when Black is still good after 23. Bxf3 Red8 (Not 23... Rad8 24. Qxa4 Nb6 25. Qa5 ))23. Nh4! Now f2-f4-f5 is a constant threat and the knights are eager to get closer to the enmy king with Nh4(g3)-f5.
23... Bxd4 24. Rxd4 c5!? The only chance for counterplay.
(Or else Black loses a pawn after 24... Nc5 25. Nhf5 Bxf5 26. Nxf5 )25. Rxd6 Nc6 The d4 -square is usually good compensation in these positions, but...
26. Nhf5! Powerplay!
26... Nd4 27. Qd2 (Worse is 27. R6xd4 cxd4 28. Nxd4 Nc5 )(Or 27. Nxd4 Qxd6 and White does not have any (good) discovered attack. )27... Ne5 This was the position that Mamedyarov was heading to. The black knights seem perfect on their outposts, the active rook on d6 will be traded and the compensation is obvious. However, Anand had foreseen something in advance...
(Since otherwise Black is down a pawn for nothing 27... Nf6 28. Rxd8+ Rxd8 29. Nxd4 cxd4 (29... Rxd4 30. Qc2 )30. Qb4 )28. Rd5! Déjà vu! Like yesterday, the former world champion sacrifices the exchange for a pawn and attack and wins!
(Instead 28. Rxd8+?! Rxd8 29. Nxd4?! cxd4 would be dream come true for Mamedyarov. )28... Bxd5 29. cxd5 Qb6 (The trade of a knight pair multiplies the attacking potential of the first player. 29... Nxf5 30. Nxf5 Qa5 31. Qe3 Qb6 32. f4 Nd7 33. Qc3 and Black should not survive. )30. f4! Anand has a clear plan: advance the pawns in the center as much as possible, disconnect the flanks, checkmate.
(The endgame is also great for White 30. Nxd4 cxd4 31. Qxd4 Qxd4 32. Rxd4 but why to get here when there is mate instead? )30... Ng6 (Or 30... Nxe2+ 31. Qxe2 c4+ 32. Kh2 Nd3 33. Qg4 which wins a second pawn for White. )31. Bc4 Another déjà vu! The Indian GM used the same diagonal to grind down Michael Adams yesterday...
31... Qa5 32. Qf2 b5 Black tries his inly chance to distract the opponent.
(Nothing can stop the pawns: 32... Nxf5 33. Nxf5 Re8 34. e5 )33. Nxd4 (Also good is 33. Ba2 Nb3 34. Nh5 )33... cxd4 34. Ba2 b4 35. Nf5 bxa3 (Alas, after 35... b3 36. Bb1 the bishop will work again on the other diagonal. )36. bxa3 Qc3 37. e5 Perhaps the only slip in Anand's phenomenal play.
(37. d6 was more subtle, with transposition into the game after 37... Rab8 (37... Qxa3? 38. Qxd4 )38. Rd2 )37... Rab8 (Anotehr transposition is 37... Qxa3 38. d6 Rab8 39. Rd2 )38. Rd2 Qxa3 (The computer suggests 38... d3 as a good defense, but it is hard to believe that White is not mating after 39. d6 Qxa3 40. Bxf7+! Kxf7 41. Qa7+ Ke6 42. Ne3 For example 42... Rb1+ (42... Rd7? 43. Qxb8 )43. Kh2 Qb4 (43... Rd7 44. f5+ Kxe5 45. Qxd7 and wins. )44. Rf2! Qb7 45. Qd4 and the analysis can go for another twenty moves but I will leave that to you. My feeling says that the attack should be sufficient. (Even better than 45. f5+ Kd7 46. Qxa4+ Qc6 47. Qa2 Qc5 (47... Rb7 48. Qe6# )48. e6+ Kxd6 49. Qxb1 Qxe3 50. Rf3 Qe5+ 51. Kh1 which Black some chances of survival thanks to his passed pawn. 51... Kc6 52. fxg6 d2 53. Qc2+ Qc5 54. Qa4+ Qb5 55. Rc3+ Kb6 56. Qd1 White is better, but not necessarily winning. ))39. Nxd4 Now everything is under control.
39... Qc1+ 40. Kh2 Rbc8?! Losing the last hope for counterplay, according to Anand, but Mamedyarov only had seconds left to make this move.
41. d6 a3 42. Nf5 Rf8 43. d7 One more jewel in Anand's rich collection of masterpieces! Mamedyarov had had enough of it. After
(43. d7 Rcd8 44. Qd4 the only way to stop the checkmate (e5-e6) is to sacrifice a whole rook with 44... Qf1 45. e6 Qxf4+ 46. Qxf4 Nxf4 47. e7 )
