Hello everyone, I am IM Tania Sachdev and will be commenting round 6 of the World Chess Championship in Chennai
1. e4 Vishy started with 1.e4, he's definitely aiming for the kill today. but that does not necessarily mean a crazy variation. He's going to aim for a long nagging advantage.
1... e5 2. Nf3 Nc6 3. Bb5 Ruy Lopez, repeating a previous game from round 4
3... Nf6 4. d3 Bc5 5. c3 O-O 6. O-O Re8 7. Re1 a6 8. Ba4 This will transpose into closed Ruy Lopez positions if black play 8...b5 9.Bb3 d6. In these positions black aims at getting a successful ...d5 break. White aims at developing Nbd2-f1-g3
8... b5 9. Bb3 d6 10. Bg5 In these set ups this is the drawback of having the black bishop actively placed on c5 and not e7, the f6 knight gets pinned and its difficult to get out of it. Move 10 and we already have a new position. This hasn't been played before. Vishy did play against Aronian earlier this year at the Alekhine Memorial and went 10.Nbd2 instead of Bg5. The game ended in a draw without much trouble for black, so 10.Bg5 could be Vishy's improvement over his previous game. One of blacks plans could also be to play Rb8 followed by b4 to gain counter on the queenside.
10... Be6 Magnus challenges white's strong light squared bishop, also a typical motif in these lines. An interesting continuation would be 12.Be6 Fe6 13.b4 Bb6 14.a4 and if 12. Be6 Re6 13.d4. White can also continue with an alternative plan of 12.d4 Bb3 (12...Bb6?? d5) 13. ab3 ed4 14.cd4 Bb6 15.Nc3. The first line, after a4 white aims at creating a weakness for black on b5 after ab5 ab5 and then after Na3 it would be difficult for black to defend this pawn
11. Nbd2 h6 12. Bh4 Black can play 12... Bb6 just against white's d4 at any point. Normally taking Be6 with white has to be very careful and with some concrete idea. If it is not giving white something immediately black gains control over the center after fe6. Follow also the multi Twitter commentary here
12... Bxb3 13.ab3 is a typical recapture to open the a file
13. axb3 White's plan could be Nf1-Ne3 while black should try to get play on the queenside with a5-a4 or a break in the center with d5
13... Nb8 very interesting idea by Magnus, he wants to regroup with Nbd7 so he can get out of the pin. Note: for reports in Spanish visit Ajedrez Chessdom here
14. h3 turns out was not just a quiet move, white has the idea of Nh2-Ng4 subtly building pressure on the kingside
14... Nbd7 15. Nh2 Qe7 The idea is to reply Ng4 with Qe6. Once the light squared bishops are exchanged blacks queen on e6 is well placed.
16. Ndf1 white aims for the g3/e3 square aiming to get Nf5. Black after getting out of the pin has 2 ways to continue in the position either play for the d5 break or play on the queenside with a5-Bb6
16... Bb6 a typical move against whites d4/b4 at any point can continue with a5 to free the rook on a8 and for queenside activity. A sample line 17.Ne3 a5 18.Nf5 Qe6 19.Ng4 Kh7 looks optically dangerous for black but should not be any real problems. Black should play Qe6 soon to get out the pin and Kh7 is an important move against any sacrifices on h6
17. Ne3 Qe6 18. b4 black normally plays a5 so white gets rid of the double pawns and play opens on the queens side.
18... a5 19. bxa5 Bxa5 Black seems to be doing fine. though white has Nf5 but when at any time the knight jumps to f5 the d5 break for black could become a reality. For example 20.Nf5 Bb6 21.Ng4 Ra1 22.Nf6 Nf6 23.Qa1 d5 Interview with WGM Sopiko Guramishvili and WIM Ljilja Drljevic here
20. Nhg4 Bb6 21. Bxf6 Very surprising! A series of exchanges is coming after Qf6 white cannot jump with Nd5 as f2 is unprotected
21... Nxf6 22. Nxf6+ Qxf6 23. Qg4 black looks completely fin after 23...Be3 24fe3 Qe7 followed by c6
23... Bxe3 24. fxe3 Qe7 25. Rf1 c5 black threatens c4! I actually prefer black here thought its very close to equality
26. Kh2 c4 And we have c4, Magnus is pressing! Initially I thought 27. d4 is not possible, but I was wrong white's idea is 27...ed4 28.ed4 Ra1 29.Ra1 Qe4 30 Qe4 Re4 31.Ra8 Kh7 32. Rb8 and white wins back the pawn however its still very equal and much closer to a draw
27. d4 Another interesting alternative for black is 27...b4 and if 28.cb4 Rab8 29.Ra4 and now ed4 30.ed4 Qe4
27... Rxa1 28. Rxa1 Qb7 Threatening ...ed4. If white goes 29.d5 black can continue Rb8 with the idea b4 These positions are exactly what Magnus likes and is best at.
29. Rd1 even just 29...ed4 30.Rd4 Re6 and black is good, good enough for some real advantage or not is to be seen, though I can't imagine black actually being able to get anything real but with Magnus he's known to win positions which seemed impossible to win. Vishy's cautious docile play was quite unexpected. He did make a comeback against Topalov and Gelfand after losing first in the previous world championships. But today's game has not been quite in the spirit of I-NEED-TO-WIN
29... Qc6 30. Qf5 exd4 31. Rxd4 Re5 32. Qf3 white's idea is to reply 32...f5 with Qd1
32... Qc7 White can play Rd5 now trading rooks. As white's pawn structure is worse black has a better position, but its not enough to win
33. Kh1 Qe7 The game seems to be heading for a draw . Though structurally black is better. It is hard to imagine anything real for black. My guess for Vishy's uninspired play today is that after yesterdays loss he wants a break to get over it with the rest day tomorrow and will fight it out after that.
34. Qg4 Kh7 35. Qf4 g6 while white is completely stuck defending the e4 pawn and cant really move around black wants to continue improving his position with... Kg7-h5, however white can just keep doing nothing and black improving the position as he can still hard to imagine a real idea to win with black as much as he can
36. Kh2 Kg7 37. Qf3 Re6 38. Qg3 Rxe4 39. Qxd6 Rxe3 40. Qxe7 Rxe7 41. Rd5 Rb7 42. Rd6 f6 43. h4 Kf7 44. h5 gxh5 45. Rd5 Kg6 46. Kg3 Rb6 47. Rc5 f5 48. Kh4 Re6 49. Rxb5 Re4+ 50. Kh3 Kg5 51. Rb8 h4 52. Rg8+ Kh5 53. Rf8 Rf4 54. Rc8 Rg4 55. Rf8 Rg3+ 56. Kh2 Kg5 57. Rg8+ Kf4 58. Rc8 Ke3 59. Rxc4 f4 60. Ra4 And this is a blunder for white! Critical play was needed and b4 was the only correct move in the situation.
60... h3 61. gxh3 Rg6 Up to Ra4 Anand had full control on the situation and now it gets dangerous after for example 62. Ra7 f3 63. Re7+ Kf2 64. h4 Rg2+ 65. Kh3 Kf1 66. Ra7 Rg6 67. h5 Rg5 68. Ra6 f2 69. Rxh6 Kg1 70. Rf6 Rxh5+ Another endgame, another grinding for hours and Magnus is heading for a success.
62. c4 f3 and practically the game is over! Magnus pulls a rabbit out of a hat, endgame magic. Constantly posing small problems to Anand, he manages to get a winning position.
62... f3 63. Ra3+ Ke2 64. b4 f2 65. Ra2+ Kf3 66. Ra3+ Kf4 67. Ra8 Rg1 is the best move here, but even a cute underpromotion will work now, or of course at a later stage. And Anand resigns, 2 points advantage for Carlsen and a big win for the Norwegian. Thank you for following with me IM Tania Sachdev and see you at later rounds for more live commentary!
67... Rg1 0-1

Respekt vor der Leistung und vor dem Durchhaltevermögen des Herausforderers! Unnachahmlich hat er eine remisliche Stellung so lange geknetet, bis sein Gegner Ungenauigkeiten / Fehler machte. Ich war vor der WM eher der Meinung, dass aufgrund mangelnder Matcherfahrung Carlsens eher Anand die besseren Chancen haben würde, doch zur Halbzeit liegt dieser schon mit 2 Niederlagen zurück. Manche halten das schon für eine Vorentscheidung - mag auch so sein. Nun muss Anand wohl seine "Killervarianten" auspacken, um den Rückstand wieder aufzuholen. Den Ruhetag morgen wird er gut gebrauchen können.

Es ist schon faszinierend, wie Carlsen Anand in scheinbar völlig remislichen Stellungen doch noch zu Fehlern verleitet. Parallelen zur 5. Partie sind unverkennbar. Es ist sicher auch eine Fage der Kondition, also der Fähigkeit, sich auch nach Stunden noch voll konzentrieren zu können.
Zwar ist Anand noch Weltmeister, aber immerhin hat Carlsen außer der besseren Kondition auch noch rund 100 Elo-Punkte mehr. Am Brett hat Carlsen offenbar die Nervosität aus den ersten Partien abgelegt. Zeitweise saß er provokant lässig auf seinem Stuhl, die Beine fast auf dem Tisch; etwa wie ein Schuljunge beim Fernsehkucken.
Carlsen wäre der erste Weltmeister aus Europa seit Max Euwe, der von 1935-37 den Titel innehatte.
