Sinquefiled Cup: the day of missed opportunities 

All three games of the penultimate round of the sinquefiled Cup were drawn. At least two players - Caruana who already assured first place and the world champion Magnus Carlsen missed winning chances. The fatigue must be taking over the players. 

CARUANA - NAKAMURA
Spanish game
1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0–0 Nxe4 5.d4 Nd6 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8 The Berlin endgame took place in the tournament for the second time and again in Nakamura's encounter. American again got tortured but this ime with an opposite color.  9.h3 Ke8 10.Nc3 h5 In the previous round Topalov played 10...Ne7 against Hikaru. 11.Bf4 Be7 12.Rad1 Be6 13.Ng5 Rh6 14.Rfe1 Bb4 15.g4 hxg4 16.hxg4 Ne7 17.Nxe6 Rxe6 18.Kg2

18...Rd8 After the game American noted more precise is 18...Bxc3 19.bxc3 Rd8 - as it was played in Anan-Karjakin encounter at the Candidates-2014 and earlier in rapid Karjakin-Grischuk. 19.Rxd8+ Kxd8 20.Rd1+ Kc8 The problem with 20...Ke8 is 21.Ne2! with the idea of 21...Ng6 22.Bg3 Nxe5 23.Nd4 (black king takes a good for the rook square) 23...Re7 24.Nf5. 21.Bg3!? Bxc3 22.bxc3 Rg6 Apparently this isn't the most precise move as long as Whte develops initiative with the next move. 23.Rd4!

23...f5!? 24.Bh4!? a more logical continuation - 24.exf6 gxf6. 24...c5 25.Rf4 Nd5 26.Rxf5 Rxg4+ 27.Bg3 Kd8!? / 27...Kd7 would be followed by 28.e6+!. 28.Kh3 / 28.e6 Nf6 29.Rxc5 c6 gives nothing =. 28...Rg6 / 28...Re4 looks risky. 29.c4!? Ne7? After some tough decisions Black blunders. Perhaps 29...Nc3! ould hold. 30.Rf8+ Kd7 31.f4! Ke6 / 31...Rh6+ 32.Kg4 g6 is refuted 33.Bh4! Nf5 34.Kg5 Rxh4 35.Rxf5. 32.Bh4 Rh6 33.Re8 g5 34.fxg5 Rg6 35.Kg4 Kf7 36.Rh8 Ra6 37.Rh7+ Kf8 38.Rh6?! Apparently 38.Bf2! would bring White decisive advantage. 38...Ng6 39.Kf5!? Kg7? Black should have played 39...Ne7+.

40.Bf2? Caruana couldn't explain why he missed such a simple win after the game: 40.Rxg6+! Rxg6 41.e6, Black is forced to play 41...Kh7 42.e7 Rg8, and any rational move wins here. 40...Ne7+ And Nakamura escaped. 41.Ke4 Ra4 42.Re6 Nc6 43.Kf5 Rxc4 44.Rg6+ Kf8 45.Rf6+ Kg8 46.g6 Rxc2 47.Be3 Nd4+ 48.Bxd4 cxd4 49.Rf7 d3 50.Rd7 Rf2+ 51.Kg5 Rg2+ 52.Kf6 Rf2+

53.Kg5 In caase of 53.Ke7? d2 54.Kd8 c5 55.e6 c4 56.e7 c3 (or 56...Re2) 57.e8Q+ Rf8 Black wins. 53...Rg2+ 54.Kf6 Rf2+ 55.Kg5 Rg2+ 1/2

The encounter between world's #1 and #2 would especially please rook engame fans.

CARLSEN - ARONIAN

41...h5? Most probably 41...Ra3+ 42.Ke4 Rxh3 с идеей 43.Rc6 Ra3 44.Rxc5 Kf6.. would lead to a draw. 42.gxh5 Ra3+ 43.Ke4 c4 44.Kd4 c3 45.Kd3 Kh7 / 45...Rb3 winning is 46.Kc2 Rb5 47.Rg6+! Kf7 48.a6 Rxh5 and here for instance 49.Rc6.

46.h6? GM Ben Finegold consulted the computer and showed the way to victory in the commentators' booth: 46.Kc2! Kg7 47.h6+ Kh7 48.h4 Kh8 49.Ra7 Kg8 50.a6 Kh8 51.h5 Kg8 52.Rg7+ Kh8 53.a7 Ra2+ 54.Kb1. 46...Rb3! 47.Kc2 Rb5! 48.Kxc3 Rf5

And despite three (!) extra pawns, White is not able to win. Black defends easily: a5-pawn is attacked from the side, checks don't allow white king to help the rook and if white places the rook on a8 and the pawn on a7, Black will put the rook behind (on a6). 36 more moves were made before Carlsen accepted the draw.

In Vachier-Lagrave-Topalov encounter Bulgarian GM played confidently most of the game, but closer to the time control he failed to raise all possible problems for the rival. 

VACHIER-LAGRAVE - TOPALOV

Here Veselin had to play 36...Bf8!.
