1-0 Karjakin, Sergey (UKR) 1-0 Mamedyarov, Shakhriyar (AZE)
Game 1 has yielded a draw already, GM Jakovenko and GM Gelfand will go into the next round
tied 0.5-0.5 as will Ruslan Ponomariov and Vugar Gashimov, but GM Vladimir Malakhov upset the #3 seed Peter Svidler using the black pieces, as Mamedyarov and Karjakin seem to be in a drawn game..whoops blunder on move 49...Rb2 by GM Mamedyarov...he was holding a draw...but this has been a long tournament and GM Karjakin is younger, stamina is REALLY key in these long tournaments, people think chess is just sitting there, it's not, you need a strong body to go with the strong mind, why GM's usually peak around 25-30, Karjakin is just 19.
GM Svidler vs GM Malakhov

1.e4 e5 2.Nf3 Nc6 3.Bb5 Good day everyone, welcome to the World Cup live commentary. The game of our choice if a match between Karjakin and Mamedyarov. Both players have been very convincing in the previous four rounds, in particular the Azeri player never had to play the tiebreak games, having won six out of eight games with classical time control.
We have Ruy Lopez on the board, but Mamedyarov also used to defend with the Kan Sicilian.
3... a6 4.Ba4 Nf6 5.O-O Nxe4!? Perhaps a small surprise, as Mamedyarov usually employs Steinitz variation and/or g6 hybrids, but he used the Open Ruy Lopez in his younger days.
6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.Nbd2 After several "tabya moves", we reach the first crossroad. White has a range of different systems, beginning with the most popular 9. c3, which we remember from the epic matches between Karpov and Korchnoi, then 9. Be3, and finally 9. Qe2 with idea Rd1 and c4.
9... Nc5 GM Ivan Sokolov, one of the world's greatest experts in Open Ruy Lopez, tried 9...Be7 here. But Nc5 is leaving white Knight on d2 for the time of being, and that piece is shutting the dark-squared Bishop on c1. Also, black is keeping the option of exchanging the Bb3.
10.c3 Be7 Grandmasters Yusupov and Marin, also great experts for the Open Spanish, trusted in this logical and developing move.
Earlier, Mamedyarov preferred 10...d4, after which white has a choice - to chase the small advantage with something like 11. Bxe6 Nxe6 12. cxd4 Ncxd4 13. a4 Be7 14. Nxd4 Nxd4 15. Ne4, or try the attack with 11. Ng5 Qxg5 12. Qf3 O-O-O 13. Bxe6+ fxe6 etc.
10...Bg4 is the third solid option.
11.Bc2 White is taking the opportunity to preserve the light-squared Bishop.
11... d4 More common is 11...Bg4, but the game move was also played by the former world champion Vladimir Kramnik in one of his games.
12.Nb3 12. cxd4 Nxd4 13. Nxd4 Qxd4 14. Nf3 Qxd1 15. Rxd1 O-O
12... d3 13.Bb1 Of course, 13. Nxc5 was also tested on numerous occasions, but 13...dxc2 14. Qxd8+ Rxd8 15. Nxe6 fxe6 16. Be3 Rd5 17. Rfc1 Nxe5 18. Nxe5 Rxe5 19. Rxc2 and it looks like black can hold this endgame without much trouble.
13... Nxb3 14.axb3 Bf5 15.b4 Probably a novelty, 15. Be3 was automatic in all previous games, and even Karjakin played it in the game against Yusupov.
15... O-O 16.Re1 Qd5 17.h3 Rfd8 Black should carefully consider all pros and cons when making such move, because after pushing b3-b4 white has Ba2 to press on f7.
18.g4 After 18...Be6, black should count with 19. Re3, but maybe 19...h5, conveniently supported by Be6, would provide sufficient counterplay against the rushed white pawns. 18...Bg6 19. Ba2 allows white to grab a powerful diagonal and perhaps prepare e6 advance.
18... Be6 19.Re3 h5 Mamedyarov goes for the variation where his pieces are more active.
20.Qxd3 20. Rxd3 Qc4, it looks like the Queen is clumsy, but white can't do any harm to that piece. Further, the Queen is pressing g4.
20... Qxd3 21.Bxd3 hxg4 22.hxg4 But now there is no time for 22...Bxg4 as white has the nasty 23. Be4 pin. Then 23...Bd7 24. Rd3 Be8 25. Rxd8 Rxd8 26. Bf4 (a6 hanging) Nb8, with a positional advantage for white.
22... Bd5 Karjakin is still pondering his next move. White has an extra pawn, but the pieces are still poorly coordinated. In addition, white will have to constantly care about e5 and g4-pawns, and in some lines black can push a6-a5 to get rid of his own weakness and open another front.
23.Bc2 It was not easy to suggest the best move for white. 23. Be4 saves the e5-pawn for the time of being, but black has immediate a5 which offers a solid counterplay.
23. Be2 a5! 24. Bxb5 axb4
23... Bxf3 24.Rxf3 Nxe5 25.Rh3 Now not 25...Nxg4? as 26. Bh7+ Kf8 27. Be4 wins the exchange.
25... g6 26.g5 With idea to nail the black pawn on f7, but also Be4 and/or Bf4.
26... Re8 Probably clearing the d8-square for other Rook and preparing Bf8-g7.
27.Bf4 Bf8 28.Re3 28. Be4 deserved attention.
28... Bd6 29.Bb3 29. Be4 Nf3+!? leads into a nice variation, where black seems to be able to survive.
29... Nc4 30. Rxe8+ Rxe8 31. Bxd6 Nxd6 32. Rxa6 gives tremendous counterplay to black.
30.Bxc4 Bxf4 31.Rf3 Bh2+ This fine point serves to drive white King away from f2 and earn a tempo if Re2 is possible sometimes. But 31...bxc4 32. Rxf4 Re5! also looked good, as then the threat is Rxg5 with check.
32.Kxh2 bxc4 33.Rf4 Re5 Black should be fine in this endgame as long as his Rooks are active.
33...Re2 34. Kg3 Rxb2 35. Rxc4 and white is somewhat better.
Re5 is better, because after 34. Rxc4 Rxg5, white should think how to prevent Kg7-Rh8.
34.Rxc4 Rxg5 35.Ra5 Rxa5 36.bxa5 Ra7 37.Kg3 Kf8 38.Kf4 Ke7 39.b4 Kd7 To protect c6 before activating the Rook.
40.Ke5 Rb7 Perhaps with idea Rb5-f5. Black should eliminate the white f-pawn.
41.Rd4+ Testing the black to see where the King goes. Kc6 is better than Ke7.
41... Kc8 42.Kf6 Rb5 43.Rf4 Rd5 Black is waiting for 44. Kxf7 g5
44.Kxf7 g5 45. Rg4 Rf5+ and 45. Rf3 g4
45.Rf6 Rd3 Mamedyarov accepts to trade a-pawn for c3. 45...Kb7 46. Kg6 g4 47. Rf4 and there is no check on f-file nor black can transfer the Rook behind the g-pawn.
46.c4 Obviously, Karjakin was not convinced that 46. Rxa6 Rxc3 with next Rb3 and/or g4-g3 would bring him the full point. He wants to give the b-pawn and push c5-c6 in an attempt to lock the black King.
46... Rd4 47.c5 Rxb4 48.c6 Kd8 49.Rf5 An attempt to attack the black King. 49...g4 50. Rg5 Rf4+ 51. Ke6 Re4+ is forcing white to search for other ways.
50. Rd5+ might be a better way, Kc8 51. Rg5 Kb8 52. Rg8+ Ka7 when the King is sidelined.
49... Rb2? An error, because white suddenly can push f4 thanks to the clumsy position of the black King. Better was 49...g4
50.f4 Rf2 The point is that after 50...gxf4, black's own pawn is distracting the Rook from checking white King, and white wins with 51. Rg5.
51.Rd5+ Kc8 52.Ke7 With two forcing moves, white cleared his pieces from the f-file and is ready to take fxg5 in the next move. Black is hopeless against the g-passer and Mamedyarov resigned. 1-0
