[Event "Reykjavik Open 2015"] [Site "Reykjavik ISL"] [Date "2015.03.13"] [Round "5.1"] [White "Mamedyarov, Shakhriyar"] [Black "Gretarsson, Hjorvar Steinn"] [Result "1-0"] [ECO "D37"] [WhiteElo "2756"] [BlackElo "2554"] [Annotator "Sagar Shah"] [PlyCount "51"] [EventDate "2015.03.10"] {With this win, Mamedyarov becomes the sole leader of the tournament. 5.0/5. The thing that this most impressive about this game is not just the fact that Mamedyarov beat a strong 2554 opponent in just 26 moves but all his moves were just so precise. There was not even one sub optimal move. All of them were the engine's first choice. This just shows how strong this Azerbaijani player really is.} 1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nc3 Be7 5. Bf4 {The Bf4 variation in QGD has become very popular after Vishy Anand used it successfully in the World Championship.} O-O 6. e3 Nbd7 7. Qc2 {This is not as popular as c5 but is an important alternative and leads to a much more fluid positions out of the opening.} (7. c5 {was Anand's choice.}) 7... c5 8. Rd1 Qa5 (8... cxd4 {is the other option and White replies with} 9. Rxd4 {Such moves are very typical of Mamedyarov. Though this is opening theory, I have often seen him lifting his rook and placing it right in the center of the board!} Qa5 10. Bg3 Nb6 11. Nd2 dxc4 12. Bxc4 Nxc4 13. Nxc4 Qa6 14. O-O $1 $14) 9. Nd2 {This move is quite common in the Cambridge springs variation. White would like to break the pin on the c3 knight, at the same time he is ready to take on c4 with his knight and Nb3 could be possible in some cases.} cxd4 10. exd4 {At first sight this position looks very weird to me. Mainly because Black is ahead in development. White has his pieces clumsily placed. What exactly is the rook doing on d1? But praxis and experience has shown that slowly White will unwind and he will find his pieces on exactly the squares he wanted them to be on.} dxc4 {Just about everyone has taken on c4. The question to be asked is, Why should one take on c4 and speed up White's development? Let's have a look at the other options.} (10... b6 $2 11. Nb3 Qa6 12. cxd5 $16 {is no good.}) (10... Nb6 $2 11. Nb3 {leads to huge material losses or traps the queen.} Qa6 12. cxd5 Nc4 13. d6 $18) (10... Bb4 $6 11. Bd3 $14) (10... Nb8 $5 $146 {could be a very worthy alternative. The knight is relocated in such a fashion that it can jump to the ideal c6 square.} 11. Nb3 Qd8 12. c5 b6 $132 {Black seems to be doing fine! We might see this move 10...Nb8 in some top level game pretty soon! :)}) 11. Nxc4 Qd8 (11... Qf5 12. Qxf5 exf5 13. Be2 $14) 12. Bd3 Nb6 13. O-O Nxc4 $6 (13... Nbd5 {would be ideal but there are some issues with the h7 pawn.} 14. Nxd5 exd5 (14... Nxd5 $2 15. Bxh7+ Kh8 16. Be5 $16) 15. Ne5 $14 (15. Ne3 $5 $14 )) 14. Bxc4 {A few moves ago we said that the White pieces looked pretty disorganized. Have a look at them now. They are so perfectly placed.} Qb6 { From this point onwards, Mamedyarov's play is worth studying.} 15. Rfe1 $1 {A very nice move bringing the rook into the game.} Re8 (15... Qd8) (15... Rd8 16. d5 $36) 16. Nb5 $1 {A fork on c7 is threatened.} Nd5 17. Bxd5 Qxb5 (17... exd5 18. Nc7 $18) 18. Be4 $1 {A threat to the h7 pawn.} g6 (18... f5 19. Bd3 {The e6 pawn would be quite weak.}) 19. Re3 $1 {Fantastic move! The rook is perfect on the thrid rank. Not only can it go to the kingside but it can also swing over to the queenside and create some damage.} a5 {Not seeing anything good that can be done, Gretarsson comes up with the idea of playing a5-a4 in order to take away the b3 square from the rook. He can then develop his bishop to d7. But this is just too slow.} (19... Bd7 20. Rb3 $16 {loses a pawn.}) 20. Be5 { Trying to probe the Black kingside.} a4 (20... f6 21. Bxg6 $1 fxe5 22. Bxh7+ Kh8 23. Rh3 $18) 21. Rg3 {The threat now is to sacrifice a few things on g6!} f5 {This is sort of forced but now the e5 bishop can never be dislodged.} 22. Bd3 Qd7 23. Qe2 {Threatening Bb5.} Bh4 (23... Ra5 24. Qd2 Bd8 25. h4 $18 {With a powerful attack.}) 24. Bb5 Qe7 25. Rc3 $1 {The rook is threatening to infiltrate on c7.} Bd7 26. Bxd7 {After Black takes the bishop, the rook comes in on c7 and combined with the bishop, it will soon end in mate. I agree that Gretarsson's play was not the best, yet the simplicity with which Mamedyarov played was just mind boggling. His moves were such that they could be easily understood but extremely difficult to imitate. This is the sign of a true genius!} 1-0
