World Chess Championship 2013 round 10: Magnus Carlsen is the new world champion

In my continuing coverage of the World Chess Championship between Anand and Carlsen, today I cover round ten, in which a draw gave 22-year-old Magnus Carlsen the FIDE World Chess Champion title. Congratulations to Carlsen, and thank you, Anand, for showing your fighting spirit by playing the Sicilian Defense today!

Game and notes below:

My opening predictions for today

I announced my opening predictions the night before today’s game.

My primary prediction was that Carlsen would play 1 e4 and Anand would play c5 for an aggressive Najdorf Sicilian, and that Carlsen would play a Be2/Nf3 line in response. My secondary prediction was that if Carlsen played something other than 1 e4, then Anand would try a King’s Indian as Black.

Summary of the game

It turns out that I was partially right in my prediction. There was a Sicilian Defense, and Anand did try entering a Najdorf. I was very happy to see this, because there was some discussion among my chess friends yesterday about whether Anand would simply play for a safe, quick draw, rather than try to fight back in the match for a win. Anand did try to fight back after all, playing the riskiest variation even against Carlsen’s avoidance of the Najdorf with the drawish Moscow Variation.

Objectively the middlegame was very equal for some time, as Anand set up a Hedgehog position against Carlsen’s Maróczy Bind setup. In fact, Anand implicitly offered a draw by shuffling his King back and forth. Carlsen decided to play on for a win, advancing on the Queenside with a4.

Shortly after that, Anand started slipping a bit, allowing Carlsen to improve White’s position, and at one critical point Anand made a big blunder that should have lost the game, hanging the important d6 Pawn to White’s capture by the e5 Pawn. But Carlsen prematurely captured the Pawn too early, allowing Anand to regain it and simplify into a Knight and Pawn ending that should be a draw.

However, White had chances because of the Queen side majority and more active King. Anand found very sharp counterplay that caused Carlson to decide to stop playing for a possible win, and shut the game down for a draw.

The state of the match

Carlsen is the new world champion!

White: Carlsen, Magnus
Black: Anand, Viswanathan
Result: 1/2-1/2

Side to move: white

Last move: 1.  variations:
Next move: 1. e4  variations:

1. e4 c5
 
A Sicilian, as I had predicted from Anand to play for a win as Black.
 
2. Nf3 d6
 
Anand wants to go into the Najdorf.
 
3. Bb5
 
But Carlsen promptly plays the drawish Moscow Variation.
 
3... Nd7
 
The most ambitious but risky response, avoiding both the trade of Bishops known to be drawish, and Nc6 which allows doubled Pawns.
 
4. d4 cd4 5. Qd4 a6 6. Bd7
 
One pair of minor pieces traded off now.
 
6... Bd7 7. c4
 
Establishing a Maroczy Bind pawn structure.
 
7... Nf6
 
[7... e5 A Najdorf-style e5 is fine here but Anand must have decided it is too drawish and he has to go for a Hedgehog to play for a win.]
 
8. Bg5
 
Stopping g6.
 
8... e6
 
Now we have a Hedgehog type of Pawn structure.
 
9. Nc3 Be7 10. O-O Bc6 11. Qd3
 
Preparing for Nd4.
 
11... O-O 12. Nd4 Rc8 13. b3 Qc7?!
 
Looks passive to me. [13... Qa5 More aggressive development.] [13... Bd7 Preserving the Bishop might have been a better winning try in this equal position.]
 
14. Nc6
 
Another pair of minor pieces traded off.
 
14... Qc6 15. Rac1 h6
 
To break the pin in order to enable the Knight to be redeployed, but does weaken the King side some.
 
16. Be3 Nd7 17. Bd4?!
 
[17. f3 Overprotecting the e4 Pawn was a thematic way to retain more tension and avoid more piece trades.]
 
17... Rfd8 18. h3 Qc7
 
Trying to redeploy the Queen.
 
19. Rfd1
 
OK, all the pieces are now developed. The position looks equal. How can either side make progress? In a regular Hedgehog with no pieces traded off, White tries to prevent Black b5 and d5 breaks while attacking on the King side with f4 and possibly e5 or f5.
 
19... Qa5 20. Qd2
 
Threatening Nd5.
 
20... Kf8 21. Qb2
 
Possible ideas along the diagonal to g7.
 
21... Kg8
 
Black can only sit and wait. White can take the draw or press on.
 
22. a4!?
 
Carlsen plays for the win rather than take the draw. Stopping b5. Also, White may have plans of playing on the Queen side also, with a possible b4 and then a5 or c5, if sufficiently prepared.
 
22... Qh5 23. Ne2
 
Maneuvering continues.
 
23... Bf6 24. Rc3
 
Aiming to double Rooks on the d file possibly.
 
24... Bd4
 
Another pair of pieces traded.
 
25. Rd4 Qe5!?
 
An active position for the Queen, but my first thought would be, might it be exposed to a possible f4? But Black can aim for b5 by keeping the Queen here. [25... Nc5 Looks like a safe way to protect the d6 Pawn while also hovering over White's Queen side a4 and b3 Pawns as well as e4 Pawn.]
 
26. Qd2 Nf6?
 
Doesn't this allow ganging up on the d6 Pawn and also leave the Queen side undefended? [26... Nc5 Black's Knight looks better on c5. 27. Re3 Looks tenable for Black.]
 
27. Re3
 
[27. Rcd3 This obvious move is not bad but Carlsen must have wanted to prevent b5. 27... b5 It's now or never for Black. 28. cb5 ab5 29. a5 Creating a Passed Pawn but Black should have counterplay.]
 
27... Rd7
 
Preparing to double Rooks as well.
 
28. a5
 
Nice. Somehow in the past couple of moves, White has improved his position considerably, while Black's has gotten clearly worse. White has b4 and f4 ideas in the air.
 
28... Qg5??
 
A losing blunder.
 
29. e5
 
Uh oh, White gets in the thematic e5 break.
 
29... Ne8 30. ed6?
 
Too quick to take the Pawn, missing the win. [30. Nc3 Computer says to just maintain the pressure, get in b4 and f4, and win the d6 Pawn at leisure.]
 
30... Rc6 31. f4 Qd8 32. Red3 Rcd6 33. Rd6 Rd6 34. Rd6 Qd6 35. Qd6 Nd6
 
We are in a Knight and Pawns ending now. White has a Queen side majority. Obviously, White has the advantage here.
 
36. Kf2 Kf8 37. Ke3 Ke7 38. Kd4 Kd7 39. Kc5 Kc7 40. Nc3
 
A critical moment. White may hope to somehow push b4, b5 and break through. It looks hard. Meanwhile, White has left the King side undefended though.
 
40... Nf5
 
Trying to go for White's g2 Pawn etc. But seems risky because of White's Knight getting to e4. [40... g5 How about immediately disrupting White on the King side? 41. g3 (41. fg5? hg5 Black has a passed e Pawn. Black should hold.) 41... gf4 42. gf4 Looks complicated also, and dangerous for Black.]
 
41. Ne4 Ne3
 
Trying for active counterplay.
 
42. g3 f5
 
Very loosening. Either this works or it doesn't. It turns out Anand's active plan to force a draw does work, even though it looks scary.
 
43. Nd6 g5 44. Ne8 Kd7 45. Nf6 Ke7
 
Abandoning the Queen side.
 
46. Ng8
 
[46. Nh5 Another option in which Black gets to Queen but White does not lose a Knight. 46... Kf7 47. Kb6 Kg6 48. Kb7 Kh5 49. Ka6 gf4 50. gf4 e5 51. Kb6 ef4 52. a6 f3 53. a7 f2 54. a8Q Kh4 55. Qf3 f1Q 56. Qe3 f4 Queen and Pawn ending that I presume is a draw.]
 
46... Kf8 47. Nh6
 
White sacrifices the Knight for some Pawns in order to get at the Queen side. [47. Nf6 Ke7]
 
47... gf4 48. gf4 Kg7 49. Nf5 ef5 50. Kb6 Ng2 51. Kb7 Nf4 52. Ka6 Ne6 53. Kb6 f4 54. a6 f3 55. a7 f2 56. a8Q f1Q
 
Wow, both sides have Queened but it's a draw.
 
57. Qd5 Qe1 58. Qd6 Qe3 59. Ka6 Nc5 60. Kb5 Nb3 61. Qc7 Kh6 62. Qb6 Qb6 63. Kb6 Kh5 64. h4 Kh4 65. c5 Nc5
 
A nice drawing finish.
