Tashir 01: Grischuk cleans up

[Event "Petrosian Memorial 2014"] [Site "Moscow RUS"] [Date "2014.11.04"] [Round "1.1"] [White "Ding, Liren"] [Black "Kramnik, Vladimir"] [Result "1/2-1/2"] [ECO "D35"] [WhiteElo "2730"] [BlackElo "2760"] [PlyCount "81"] [EventDate "2014.11.04"] [SourceDate "2014.01.04"] 1. d4 Nf6 2. c4 e6 3. Nc3 d5 4. cxd5 exd5 5. Bg5 c6 6. e3 (6. Qc2 {is a way to prevent the variation that happened in the game, but it also allows its own side variations.}) 6... Bf5 {Much to my personal displeasure people are starting to figure out that this endgame with the double-pawns on f6 and f7 is not that bad for Black.} 7. Qf3 Bg6 8. Bxf6 Qxf6 9. Qxf6 gxf6 10. Nf3 Nd7 11. Nh4 {There isn't much in the way of set theory in this variation. White has long-term pressure against the f-pawns but Black is very solid, he has the pair of bishops and he will have many active pieces after maneuvering to the right spots.} Be7 12. g3 Nb6 {The knight is going to d6 where it can later choose on e4 or c4 depending on the circumstances.} 13. O-O-O Nc8 14. Bd3 Nd6 15. Kc2 Kd7 16. f3 Bxd3+ {You know that White must have a hard time converting anything in this position, or even proving an advantage, when Black can get away with just trading off the g6 bishop.} 17. Kxd3 f5 18. Ng2 h5 19. h4 Rag8 20. Rh3 {Black has pressure on g3 and it's very hard to do anything with White besides have a pretty knight on f4. Ding Liren simply doesn't find a way forward from him.} Ne8 21. Ke2 Bd6 22. Kf2 Nf6 23. Ne2 a5 24. b3 Re8 25. Rhh1 Re7 26. Nef4 Rg8 27. Rd2 Ree8 28. Rc2 Kc7 29. a4 Kd7 30. Rh3 Rg7 31. Nd3 Kc7 32.

Nc3 Qd6 10. Be3 Be7 11. Nd2 Nd5 (11... Nb4 12. Nc4 Qd8 {is an old game between Gufeld-Taimanov, 1963.}) 12. Nde4 Qd8 13. Nxd5 exd5 14. Nc5 { White has the better side of this symmetrical pawn structure as he is better developed.} O-O 15. Rc1 f5 $5 {Mixing it up! This will cause long-term weaknesses but the immediate activity might be uncomfortable to deal with for White.} 16. Nd3 (16. g3 f4 17. Bxf4 Rxf4 18. gxf4 Bd6 $13) 16... Bd6 17. f4 $6 {It wasn't necessary to play the same game.} (17. Bf3 f4 18. Bd2 {kind of asking Black "so what".} Be6 (18... Nxd4 19. Bxd5+ Kh8 20. Rc4 $1 {Is "the point" as Black cannot save his f4 pawn.} Ne6 21. Qh5 {and White's clearly controlling the board.}) 19. Bc3 Qf6 20.

Bxc5 Qxc5 26. Bf3 {White still retains an edge in this endgame with the passed pawn and pressure on d5, but with only one weakness to protect Morozevich's defenseive task is not the hardest.} Rc8 27.

With so many pieces still on the board and as much development as Black has there must be a way to obtain enough counterplay to justify the weakness in the center of the board.} 12. Nce2 Be5 13. Nxc6 bxc6 14. Bxe5 Rxe5 15. Ba4 c5 16. Bxd7 Qxd7 {The hanging pawns are a liability in the endgame, but we are not quite there yet and White does not have too much to work with.} 17. Rc1 Rc8 18.
