[center]BLACK: Vishy Anand[/center]
[center][/center]
[center]WHITE: Magnus Carlsen[/center][center]Position after 11...Bb4c3+[/center]

12.bxc3

• White has the advantage with the Bishop pair and more space, but he also has more pawn weaknesses.

12...Kc7 13.h4 b6 14.h5

• White moves to prevent kingside counterplay from Black before it begins.
• [font color="red"]14.Rd1 Nc5 15.Rd4 h6 16.Rh3 Bd7 17.Rg3[/font] still gives White the advantage with the active Rooks; each side has a bad Biswhop and White's other Bishop is inactive.

14...h6 15.0-0-0

• This is more to get the Rook to d-file than to bring into safety.

15...Bb7 16.Rd3 c5 17.Rg3 Rag8

• Black plays his best chance, which is still counterplay on the kingside. He puts both his Rooks behind the kingside pawns in order to enforce ...g5.
• If [font color="red"]17...Rhg8?! 18.Bd3 b5 19.f3[/font] then:
• If [font color="red"]19...f5 20.Bxf5!! exf5 21.e6+[/font] then:

• [font color="dodgerblue"]21.Bxh7 Rxh7 22.fxg5 Be4 23.Rhh3 Rhg7 24.a4[/font] gives White an extra pawn; Black maintains pressure on White's important g-pawn.
• [font color="darkblue"]20.hxg6!? Nxg6! 21.Rh5 Ne7 22.Rxg8 Rxg8 23.g3[/font] gives White an attack on Black's weak h-pawn.

• [font color="red"]21...Ne7 22.Rxg8 Rxg8 23.g3 Rd8 24.Be2 Be4 25.Rxh6[/font] gives White an extra pawn; Black's Knight has play against White' e-pawn and the Rook has command of the d-file.

22.Bc2 Kb7

• Black should take advantage of the fact that White cannot take command of the d-file and bring his King to where it can assist in the defense.
• If [font color="red"]22...Ne7 23.Rxg8 Rxg8[/font] then:
• If [font color="red"]24.g3[/font] then:
• [font color="red"]24...Ng6 25.Rxh6 Nxe5 26.Bf4 Kd6 27.Kd2 Rf8 28.Ke3[/font] gives White more freedom.

[center]BLACK: Vishy Anand[/center]
[center][/center]
[center]WHITE: Magnus Carlsen[/center][center]Position after 24.Bc2d1[/center]

• White may be afraid of ...b5 and wants the Bishop on e2 to protect against a pawn exchange on c4.
• If [font color="red"]24.Rg3 Ne7 25.Rxg8 Rxg8 26.g3 Ng6 27.Bd1[/font] continues to give the advantage; he will shortly capture on h6.

24...Rd8!

• Black will sacrifice the h-pawn to double his Rooks on the d-file.

25.Bc2!

• This is a foresighted move. White uses the Bishop to shield the d1 square from the Black Bishop.

• If [font color="red"]26.Bc2 Ka6[/font] then:

• [font color="#ECA11A"]27.Bxh6!? Rh8 28.Bxg6 fxg6 29.Rh4 Ba4 30.Kb2 Rd1 31.Rxg6[/font] is equal.
• If [font color="darkred"]26.Be2 Rd7[/font] then:
• If [font color="darkred"]27.f3 Rgd8 28.Bxh6 Ba4[/font] then:
• If [font color="darkred"]29.Be3[/font] then:
• [font color="darkred"]29...Ka6 30.Rgh3 Bd1 31.Bf1 Ba4 32.Be2[/font] is equal.
• [font color="purple"]29...Bd1 30.Bf1 Ba4 31.Be2 Bd1 32.Bf1 Ba4 33.Be2[/font] is equal.
• [font color="darkorange"]29.Bg5?! Rd1+ 30.Bxd1 Rxd1+ 31.Kb2 Nxe5 32.Rh4 Nd3+[/font] is equal.
• [font color="magenta"]27.Rxh6 Be4 28.Rh2 a4 29.f4 Rgd8 30.Rgh3 Ne7[/font] is equal.

25...Rdg8 26.Kd2 a4 27.Ke2 a3

• [font color="red"]27...Ne7 28.Rf4 Be8 29.Rf6 Rg4 30.Bd3 Ng8 31.Rf4[/font] gives White a small advantage; his g-pawn is taboo for Black's Rook.

28.f3 Rd8?!

[center]BLACK: Vishy Anand[/center]
[center][/center]
[center]WHITE: Magnus Carlsen[/center][center]Position after 28...Rg8d8[/center]

• This plan is now doomed. Black needs to get three attackers -- both Rooks and the Bishop -- firing at d1; with the White Bishop at c2, that is not possible.
• If [font color="red"]28...Kc7 29.Kf2[/font] then:
• [font color="red"]29...Rd8 30.Bc1 Bd7 31.Ke2 Rdg8 32.Ke1 Bc6 33.Kf2[/font] gives White a clear advantage from his pressure against Black's kingside.
• If [font color="darkred"]29...Kd8 30.Bc1 Kc7[/font] then:
• If [font color="darkred"]31.Ke2 Bd7 32.Bb1 Ba4 33.Bxa3[/font] then:
• [font color="darkred"]33...Ne7 34.Rxg8 Rxg8 35.g4 Rd8 36.Rh1 Nc6 37.Bc1[/font] gives White an extra pawn; the main center of gravity on the board is d1, a fact that helps give Black compensation for the pawn.
• [font color="burgundy"]33...Ra8 34.Bc1 Rhd8 35.Bd2 Kc8 36.Bxg6 fxg6 37.Rxh6[/font] leaves White with two extra pawns; Black has some compensation in activity.
• If [font color="magenta"]31.Bxa3?! Ra8![/font] then:
• [font color="magenta"]32.Bxg6 fxg6 33.Rxg6 Be8 34.Rg7+ Kc8 35.Rh1 Rxa3[/font] leaves Black a Bishop for two pawns.
• [font color="darkorange"]32.Bb2? Rxa2! 33.Bxg6 Rxb2+ 34.Ke3 fxg6 35.Rxg6 Bd7[/font] leaves Black a Bishop for a pawn,

29.Ke1 Rd7 30.Bc1?!

• White removes the Bishop from covering the dark squares on the d-file, which are important, to attacking the a-pawn, which is not.
• Better is [font color="red"]30.Rg3 Ra8 31.Ke2[/font] when:
• [font color="red"]31...Ba4 32.Be4+ Bc6 33.Bxg6 fxg6 34.Rxg6 Re8 35.Rhxh6[/font] leaves White two pawns to the good.
• [font color="darkred"]31...Ne7 32.Rg7 Rg8 33.Rxg8 Nxg8 34.Kf2 b5 35.Bb3[/font] leaves White taking aim at the pawns at c5 and a6.

30...Ra8?!

• Black misses the opportunity to equalize.
• [Font color="red"]30...Rhd8! 31.Bxh6 Rh8 32.Bxg6 fxg6 33.Rxg6 Ba4[/font] leaves the game level.

31.Ke2! Ba4 32.Be4+ Bc6?

• Black must now lose material.
• If [font color="red"]32...Ka7 33.Bxa8 Kxa8 34.Rxh6[/font] then:
• [font color="red"]34...Rd1 35.Bxa3 Ra1 36.Ke3 Nxe5 37.Rg7 Nxc4+ 38.Kf4[/font] leaves White an exchange up with Black pawn in danger.
• [font color="darkred"]34...Bc2 35.Bxa3 Bd3+ 36.Ke1 Ra7 37.Bc1 Rxa2 38.f4[/font] gives White the exchange plus a pawn; Black's Bishop defends the Knight that makes mobility difficult fot the Rooks.

33.Bxg6!

• White now has a winning advantage.
• [font color="red"]33.Bxh6? Bxe4! 34.Rxe4 Rb8 35.Bc1 Kc6 36.Rh1[/font] gives White only a small advantage.

33...fxg6 34.Rxg6 Ba4

• [font color="red"]34...Re8 35.Rhxh6 Ba4 36.Rxe6 Rxe6 37.Rxe6[/font] leaves White with three extra pawns.

35.Rxe6

• Although three pawns to the good, careless play can still cost White the full point.
• If [font color="red"]35.Rhxh6?! Rd1 36.Bxa3 Ra1[/font] then:
• [font color="red"]37.Rg7+ Ka6 38.Ke3 Rxa2 39.Bc1 Rd8 40.Rhh7[/font] White's Rook will get fat on Black's pawns, but White will have to work a little harder for his win than he needs to in the text.
• If [font color="darkred"]37.Rh7+?! Ka6[/font] then:
• If [font color="darkred"]38.Bxc5 Bc2 39.Rxe6 Bxh7 40.Rxb6+ Ka5 41.Rb5+[/font] then:
• [font color="darkred"]41...Ka6 42.Rb6+ Ka5 43.Rb5+ Ka4 etc[/font] draws by repetition.
• If [font color="magenta"]41...Ka4 42.Rb4+[/font] then:
• If [font color="magenta"]42...Ka5 43.Rb5+[/font] then:
• [font color="magenta"]43...Ka4 44.Rb4+ Ka5 etc[/font] draws by repetition.
• If [font color="darkorange"]43...Ka6 44.Rb6+[/font] then:
• [font color="darkorange"]44...Ka5 45.Rb5+ Ka6 etc[/font] draws.
• [font color="purple"]44...Ka7??[/font] loses immediately to [font color="purple"]45.Rb1+ .[/font]
• [font color="#CC6666"]42...Ka3??[/font] loses immediately to [font color="#CC6666"]43.Rb8+ .[/font]
• If [font color="magenta"]38.Rxe6!? Rxa2+![/font] then:
• [font color="magenta"]39.Ke3 Rxa3 40.Kd3 Rd8+ 41.Rd6 Rxd6+ 42.exd6 Ra1[/font] gives Black more activity; his drawing chances are excellent.
• [font color="darkorange"]39.Kf1 Rxa3 40.Rc7 Rxc3 41.Rxc5 Rg8 42.Kf2 Rc2+[/font] wins a pawn for Black.

35...Rd1 36.Bxa3 Ra1 37.Ke3 Bc2

• [font color="red"]37...Rxa2 38.Bc1 Re8 39.Rxe8 Bxe8 40.Rxh6[/font]gives White at least two extra pawns; this is still a position White should win, but it will be after further grinding.
• If [font color="blue"]37...Re8[/font] then White wins after [font color="blue"]38.Rg6 Rxa2 39.Bc1 Re7 40.Rhxh6 Rc2 41.Rxb6+[/font] when he has four extra pawns.

38.Re7+! 1-0

• If [font color="red"]38...Ka6 39.Rxh6[/font] then:
• [font color="red"]39...Ka5 40.Rb7 Rxa2 41.Bc1 Bb3 42.Rbxb6 Bxc4 43.Bd2[/font] leaves White three pawns to the good.
• a) If [font color="darkred"]39...Rc8 40.g4[/font] then:
• [font color="darkred"]40...Rxa2 41.Bxc5 Rxc5 42.Rh8 Rxc4 43.Ra8+ Kb5 44.Rxa2[/font] leaves White three pawns to the good.
• [font color="magenta"]40...Ba4 41.Ree6 Re1+ 42.Kf4 Rb1 43.g5 Rc7 44.g6[/font] leaves White no way to stop the running g-pawn without losing a Rook.
• b) If [font color="darkred"]39...Rb1 40.Bxc5[/font] then:
• [font color="darkred"]40...Rc8 41.Bb4 Rxc4 42.Ree6 Rcxb4 43.cxb4 Rxb4 44.Rd6[/font gives White the exchange and three pawns.
• [font color="magenta"]40...Rb8 41.Bd4 Rb7 42.Rxb7 Kxb7 43.g4[/font] gives White five extra pawns.
• Sri Anand resigns.
