Aeroflot R5: Black victories

by Alejandro Ramirez
3/31/2015 – We are a little over the halfway mark in the Aeroflot Open, and the excitement continues. Sasikirian drew two of his games in a row, allowing three people to catch up with him. Van Foreest won by default against Salgado (who withdrew from the tournament), while Nepomniachtchi and Dubov won with Black to catch up with 4.0/5. Meanwhile Mamedyarov, the top seed is struggling with 50%.

Three draws on the top boards. No one reaches 4.0/4, and only two players are now 3.5/4. One of them is the leader before this round started, Sasikirian, who drew Kovalenko.

The other person with 3.5... well he got there in a slightly different way. He was scheduled to play Ivan Salgado from Spain. With Black and being considerably lower rated, the Dutch player certainly had a tough game ahead of him. However the Spaniard didn't show up, still for reasons unknown, and forfeited his game. We will be trying to find out more about the situation and provide it in the next report.

The two leaders drew their game at the top, leaving an opportunity for the horde with 3.0/4 to win their game and catch up to first place.

Only two players managed to do this, and they both did it with the black pieces!

Nepomniachtchi convincingly outplayed Kobalia. He was able to trap his opponent's bishop on a5, away from the action, and even though that bishop never perished, it simply wasn't able to help the rest of his army on the other side of the board. It was also always a target on a5. Nepo won a pawn and cleaned up on the kingside.

Meanwhile in the Kovalenko-Dubov game, White bet all his chips on his kingside attack, while Black had an annoying passed b-pawn to create counterattack with. It became pretty clear pretty quickly that White wasn't going to breakthrough on the kingside, and Black's pawn cost White a piece and the game.

Back in board eight the game between Mamedyarov and Anton Guijarro was crazy, with Black's king waltzing to f5 with a lot of pieces still on the board... to help out on the attack! A game that we recommend you replay through. A tough loss for Mamedyarov but a good victory for the young Spaniard.

Speaking of young talented Spaniards, Ivan Salgado Lopez seems to have withdrawn from the tournament despite his great start.

The four leaders will face each other. With a little over half the tournament over, it is still anyone's event to win. Even players with 2.5/5 (50%!) can hit a hot streak, win the next four rounds and tie for first.

He was able to eliminate White's center and he has no real structural weaknesses: he will be able to play d6 and c5 securing good positions for all of his pieces, the a7 pawn is not easily attacked. 15.Rhe1 Rde8 16.Nd2 White initates a knight maneuver that is as bad as it is long. c5 17.Nb3 Bb7 18.g3 d6 19.Na5 Ba8 By now it is quite clear the knight doesn't belong on a5. 20.Bf1 Ng4 21.Bh3 h5 22.Be3 Rhf8 23.f4 Kd8 The h2 pawn and the e3 bishop are hanging. White's pieces are discoordinated. 24.Rd3 24.Bg1 Bf3 25.Rxe8+ Rxe8 26.Rf1 Ba8 concedes the e-file and the game. 24...Bd4? 24...Nxh2 was simply a free pawn. 25.Bxg4 hxg4 26.Nb3 Bxe3+ 27.Rdxe3 Rxe3 28.Rxe3 Rh8 29.Re2 Bf3 30.Rf2 Re8 Black is slightly better due to his powerful piece placement and easier play. However White has decent chances of holding. 31.Kd2 Kd7 32.Na1 Re4! 33.b3 Rd4+ 34.Ke3 Re4+ 35.Kd2 Rd4+ 36.Ke3 Rd1 37.Nc2 Rh1 38.Kd2 Rd1+ 39.Kc3 c6 40.Ne3 Rh1 41.Nf1 Black's rook is trapped, but it does not matter. White has no activity and the passed pawn on the d-file will provide enough distraction for White's pieces. d5 42.Nd2? 42.b4 was probably the only way to keep fighting, but things still look grim. 42...d4+ 43.Kc2 Ke6 44.Kb2 44.Kd3 Re1 45.Nxf3 Re3+ 46.Kc2 gxf3 44...Kf5 45.Kc2 Re1 46.Kb2 Be2 White has lost any semblance of coordination and Black's pieces are strong enough to push the d-ppawn. 47.Kc2 d3+ 48.Kb2 Rd1 49.Nb1 Rxb1+ 49...d2 also works, but the played move is much , much easier. 50.Nxd2 Rxd2+ 51.Kc1 Rxa2 52.Kb1 Rd2 53.Kc1 Rd1+ 54.Kc2 Bf3! with a winning pawn endgame if White takes on f3! 0–1
