[Event "Zurich Chess challenge Kramnik vs Aroni"] [Site "Zurich"] [Date "2012.04.24"] [Round "3.3"] [White "Kramnik, Vladimir"] [Black "Aronian, Levon"] [Result "1-0"] [ECO "C47"] [WhiteElo "2801"] [BlackElo "2820"] [Annotator "Ramirez,Alejandro"] [PlyCount "83"] [EventDate "2012.??.??"] [EventCountry "SUI"] 1. e4 {60 There is a certain irony when a valid comment is to state that both players of the match chose 1.e4 as a surprise weapon. After Aronian's 1.e4 in game two, Kramnik also chooses to employ it. True, Kramnik has played it before, but the last time he did so in a classic game was against Adams in the 2006 Dortmund SuperGM tournament. They drew.} e5 {60} 2. Nf3 {0} Nc6 {0 This is already the first decision, though Kramnik had assuredly planned this in advance. Against the more typical 3.Bb5, Aronian usually plays his pet Marshall Gambit, his primary choice to neutralize his opponent with black. Unless Kramnik wishes to draw, or somehow try to outbook one the world's foremost theoretician's in the line, he needs another plan.} 3. Nc3 {0} Nf6 {0} 4. d4 $1 {0 The exclamation is because there is no way Aronian could have expected this unless he has a crystal ball. For one thing, Kramnik has never played any form of Scotch Defense with black or white in his career. The opening motto of the match seems to be "expect the unexpected".} exd4 {120 Aronian's only foray in this line dates back to 2003, when he was 19 years old and rated 2581.} 5. Nxd4 {0} Bc5 {240} (5... Bb4 6. Nxc6 bxc6 7. Bd3 { Transposes to one of the main lines of the Scotch game. Aronian wants none of that. As he said after the game - he was playing for a win! This is a great advantage of the 'friendly' matches, as they allow players to really play for both results.}) 6. Be3 {60} Bb6 {0.00/0 60} 7. Qd2 {0.27/0 120 "Expect the unexpected" indeed! This variation has only been played twice by players even rated 2500, and only one is worth mentioning.} O-O {0.29/0 420} 8.

In some way, the Queen sacrifice that follows is somewhat forced.} (9... d6 10. g4 Nxd4 11. Bxd4 Be6 12. Rg1 Bxd4 13. Qxd4 c5 14. Qd2 Qa5 15. a3 a6 16. g5 Nd7 17. f4 b5 18. f5 Bc4 19. g6 fxg6 20.

First, he has the pair of bishops, which gives him a strong hold on some dark squares. Also, Black's pieces will swing into the game very quickly.} Ne3 {0. 54/0 1020} 15.

Bxa8 {1.50/0 0} Bb6 $1 {0.98/0 0 The problem of having an extra queen is that when it gets attacked you really have to move it. Black is building up slowly by using the Queen as a punching bag.} 19.

Re1 {0.64/0 0 Of course, every amateur will tell you that three pieces are worth more than a queen. However, in this specific instance, White also has two pawns, one of them passed! The struggle is far from over.} Rd8 {1.93/0 60} 21. Qe4 {1.07/0 0} g5 { 1.51/0 600 This is a strange move. Black seems to weaken unnecessarily.} 22. c3 {2.14/0 120} (22. b3 Bc5 23. Qb7 Ba3+ 24.

Kramnik eliminates some pieces and lets his pawns decide the issue.} (30. Qb5 $1 {is a surprising resource easily found by computers. However the Grandmasters were in time pressure and it is not so easy to calculate.} Nxb3+ 31. Kc2 Bc5 32. Re5 $18 {The bishop is trapped which means that the knight is doomed. Black has no more counterplay.}) 30... Rxe8 {2.39/0 3} 31. Qxd5 {2.19/0 1 In many ways, the smoke has cleared. Black's material is very reduced, so there is no possibility of creating serious threats against the king. Without these threats, the pawns will simply roll forward.} Rd8 {2. 13/0 93} 32. Qb5 {2.18/0 31} Rd6 {3.16/0 37} 33. Kc2 {2.86/0 63} (33. Qe5 $1 { was more accurate to prevent a little maneouvre from black, Bd8-f6, which grants him some coordination.}) 33... Kg7 {4.01/0 37} (33... Bd8 $1 {Aronian was down to his last few minutes here, and this backwards move is again, hard to find. White should still be winning in this position with accurate play, but the idea is to put the B on the a1-h8 diagonal, which combined with a N on c6 might potentially create threats against the king.} 34. Qb8 $1) 34. b4 {3. 70/0 17} Nb7 {3.26/0 0} 35. c4 {3.84/0 43 Now it's all over, Black has no coordination, and there is little hope to sacrifice one piece for both pawns.} Rf6 {4.05/0 4} 36. g4 {4.60/0 55} Nd8 {3.78/0 3} 37. c5 {4.06/0 11} Bc7 {6.48/ 0 1} 38.

Qd7 $1 {Traps the knight, but White no longer has to be very accurate, just minorly careful.}) 41... Na7 {3601} 42. Kd3 {0 The king marches in, and the knight cannot help unpin the rook. A very exciting game in which Aronian was maybe too optimistic throughout the entire game, as can be seen in some of the comments. They did provide quite the spectacle!} 1-0
