International master Vladimir Barsky prepared a review of the tenth round of the world championship among juniors. Polish GM Jan-Krzysztof Duda increased the gap, suddenly rapidly beating rival at the end, which has earned the reputation of “stringy-neutral”.
Y.-K. Duda – N. Abasov
Berlin – a favorite toy of professionals and those seeKing to replenish their ranks. On 12-meter run White chose a rare continuation, and at least for one of the contenders started an independent 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 9.h3 Ke8 10.Nc3 h5 11.Bf4 Be7 12.Rfe1 Be6 13.Ne4
Our database revealed only one party on this subject: 13…Rd8 14.c3 c5 15.Nfg5 Rh6 16.b3 Bd5 17.Rad1 Rg6 18.Kf1 Rd7 19.c4 Bxg5 20.Nxg5 Bxg2+ 21.Kxg2 Rxd1 22.Rxd1 f6 23.exf6 gxf6 24.Rd5 fxg5 25.Rxf5 gxf4+ 26.Kf3, draw, L. Milov – Zwahr, Deizisau 2015.
14.c3 14…Rh5 15.Nfg5 Rd8 16.g4 hxg3 17.fxg3 Rh6
The computer proposes to solve the problems of protection by tactical: 17…Bxg5 18.Bxg5 (harmless 18.Nxg5 Ne7) 18…Rd3! 19.g4 Rhxh3 20.gxf5 Bxf5 21.Nf2 (nothing better for White) 21…Rdg3+ 22.Kf1 Rxg5 23.Nxh3 Bxh3+, and two pawns are sufficient compensation for the quality. Abasov just takes the Rook from under the double blow.
18.Nxe6 Rxe6 19.Rad1 Rd5
Using a small tactical tricks for Black to move the knight to d5: 19…Rxd1 20.Rxd1 Ne3!, and if 21.Bxe3 (21.Rd4 Nd5), then after 21…Rxe5 Black regains the piece and fully equalize the position. Now White is trying to get a small advantage.
20.Kf2 Kd7 21.c4 Rxd1 22.Rxd1+ Kc8 23.g4 Bh4+ 24.Kf3
A gross mistake, after which Black’s situation becomes immediately desperate. The only Knight retreat – 24…Nh6. White is better, but a clear path to strengthen its position not visible, for example: 25.b4 (25 noteworthy.Bxh6 gxh6 26.Kf4, but after 25.g5 Nf5 26.Kg4 g6 Black has everything in order – the Bishop h4 unable to win) 25…b6 26.a4 Re7.
After this move, which the Azerbaijani grandmaster obviously missed, his position was hopeless: 25…Bxg5 26.Nxg5 Rg6 (26…Rxe5 27.Nxf7 – hangs the Rook and threatening mate on d8) 27.Nxf7 b5 28.Rd8+ Kb7 29.Re8 Nc8 30.c5, etc. Black resigned. Insidious Berlin – one mistake and is long protect a little worse for the end Black had to immediately lay down their arms.
Close to victory was Ulvi Bajarani, but this time fate had kept the Russian grandmaster.
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.f3 c5 5.d5 0-0 6.e4 b5 7.e5 Ne8 8.f4 exd5 9.cxd5 d6 10.Nf3 Nc7 11.Bd3 c4 12.Bc2 dxe5 13.d6 Bxd6 14.fxe5 Bb4 15.Qxd8 Rxd8 16.Be4 Nd5 17.Bg5
Black very boldly, provocatively played in the opening, and now to maintain an approximate equilibrium they were required accuracy: 17…Bxc3+ 18.bxc3 Rd7 19.0–0–0 Bb7 20.Bf5 g6 21.Bxd7 Nxd7 with sufficient compensation for the quality.
17…f5?! 18.exf6 Nxc3
Serious problems in Black and in case of 18…Bxc3+ 19.bxc3 Re8 20.0–0–0 Rxe4 21.Rxd5 Nc6 22.Rf1.
19.bxc3 Re8 20.f7+!?
Hard to resist such a cute combination, but it’s easier straight 20.0–0–0 Rxe4 21.Rd8+ Kf7 22.fxg7 Kxg7 23.Rxc8 Ba3+ 24.Kb1, and it is unclear how Black be untied. However, and now the game is dictated by Whites.
20…Kxf7 21.0–0 Rxe4 22.Nd2+ Kg6 23.Nxe4 Bb7 24.cxb4 Bxe4 25.Bd2 Nd7 26.Bc3
It was possible in any case to ruin the opponents pawn structure: 26.a4 Bd3 27.Rfe1 bxa4 28.Rxa4. But White decides to harass the enemy King.
26…Nf6 27.Rae1 Re8 28.Re3 Nd5 29.Rg3+ Kh5 30.Bd2 h6 31.Rxg7 c3
Sight lost To victory… led 32.Bxc3! Nxc3 33.Rf6 (threatening 34.g4+ Kh4 35.Rxh6#) 33…Rh8 34.Re6: White or want to give a mate – 35.Re5+ Kh4 36.g3+ Kh3 37.Rh5# or attack the Knight move Rc7 and win the figure. Was White and in a more prosaic way: 32.Be1 (with the threat of mate in one move) 32…Ne3 33.g4+ Nxg4 34.Bxc3, destroying the only card Black.
The chances of winning left 33.Rf3 Re1+ 34.Kf2 Re2+ 35.Kg3 Be4 36.Rf2 Rxf2 (36…Re1 37.Kh3) 37.Kxf2 Nxb4 38.Ke3.
33…Nxb4 34.Ba3 c2 35.Ra1 Nxa2 36.Rxa2 Re1+ 37.Kf2 Re2+ 38.Kf3 c1Q 39.Bxc1 Rxa2 Draw.
In the girls tournament first defeat suffered permanent leader Zhansaya Abdumalik from Kazakhstan.
Bivol – J. Abdumalik
In the opening of the Russian chess player has made substantial advantage: the Bishop g2 is very strong, it is difficult for Black to complete development. It’s time to open the line.
20.c5! Nxc5 21.Nxc5 dxc5 22.Bxc5 Re8 23.Nc4 e4 24.Bb6
This move suggests, but rather 24.Bd6! Bd8 25.Ba3! Bc7 26.Rac1.
24…Bxb6 25.Nxb6 Rb8 26.Rac1 Be6
Black could take advantage of a rival to a minimum, if the “held” dangerous funcitioning Bishop: 26…f5! 27.Nd5 Ne5.
27.Bxe4 Bxh3 28.f3 Be6 29.Nd7 Rbd8 30.Nc5 Rxd1+ 31.Rxd1 Bxa2 32.Bxb7 a5
In the case of 32…Bc4 33.Bxa6 (but not 33.e4? Be2) 33…Bxa6 34.Nxa6 Rxe2 35.Rd8+ Nf8 36.Nc5 Re7 (loses 36…Rxb2 37.Nd7) 37.b4 White has good winning chances.
Excessive subtlety; it was necessary to immediately engage in the pawn A5: 33.Ra1 Bc4 34.e4 Ne5 35.Kf2 and Black loses a pawn.
It is clear that the pawn on E2 can not be taken – 33…Rxe2? 34.Rd8+ Nf8 35.Nd7, but after 33…Rb8! (with the threat Bxb3) 34.Bd5 (or 34.Rd7 Nf8) 34…Rb5 35.Ne4 Bxb3 36.Bxb3 Rxb3 37.Rd8+ Nf8 38.Rb1 Nc5+ 39.Kg2 g5 40.Nd7 Kg7 41.Nxf8 a4 42.Ra8 Rd1! Black escaped, a White Knight appears with f8.
34.Rd2! Bb1 35.Bd5 Bf5 36.Ra2 h5 37.e4 Be6 38.Rxa5
Perhaps, more skillful 38.Nxe6 fxe6 39.Bc4 Ra8 40.Ra4 Kf7 41.b4 Nd7 42.Be2! (but not immediately 42.bxa5? Nb6). However, and so Whites did okay.
38…Bxd5 39.exd5 Rd8 40.Ne4 Rb8 41.Nc5 Rd8 42.Nb7 Rd7 43.Rb5 Nh7 44.Kf2 g5 45.d6 Kf8 46.Rb6 Nf6 47.Nc5 Rd8 48.Rc6 Ke8 49.b4 Rb8 50.b5 g4 51.b6 Kd8
52.b7 Nd7 53.Nxd7 Kxd7 54.Ke6 Rb6 55.fxg4 hxg4 56.Ke3 f6 57.Kd4 f5 58.Kc5 Kd7 59.Rb4 Black resigned.
The misfire of the leader took advantage of the Ukrainian chess player Natalia Bush – she has a big head carried out attack on the enemy King, won and led the race. The main events unfolded after that.
Buksa – S. Ibragimova
Both sides are attacKing Whites only come in the center, and the Black figures burst into the rival camp through the Queenside. So far, the strongest White piece associated with protection, but the Queen h3 at any moment ready to entrust defensive function of the castle to go on the attack. Black to move and now it was very important to block the road to the White Queen: 45…f5! 46.Qg3 Kh7 47.F4 Nf7 48.Qh3 Qf5! In this case, the chances of Azerbaijani chess players would be higher, because almost any endgame in Black’s favor.
Correct was 46.Qe6+ Kh8 47.Rg1 Nf4 48.Qc8+ Kh7, getting the same position that later happened in the party.
And here it was necessary 46…f5!
Impressive White won after 48.Bxf6! Options here are long and difficult to calculate, but beautiful: 48…Bxf6 49.Qc7+ Kh6 (49…Bg7 50.Ne8) 50.Nf7+ Kh7 51.Ng5+ Kh6 52.h4 Bxg5 (after 52…Bg7 53.Re8 Ra8 54.Re7 Rg8 55.Rxg7 Rxg7 56.Qb8 Black King “in the box”) 53.hxg5+ Kxg5 54.Qe7+ Kh6 55.Qf8+ Kg5 56.Re5+ Qf5 57.g3! suddenly the attack still connects g1 and Rook!
Defending against stale mate and at the same time bringing the Knight to the shock position.
Harder 49…Qc4! (connecting the Queen to the defense) 50.Rd1 (but not 50.Nxf6?+ Rxf6) 50…Ne5.
50.Nxf6+ Rxf6 51.Rxe5 Rxf3
And after 51…Rf7 52.Qd5 Kg8 53.Re6 Black bad.
52.Bf6 Rxf6 53.Re7
Delayed resistance 53…Qf2, threatening Qxg1+! Of course, after 54.Rxg7+ Kh6 55.Rh7+ Kg5 56.Qd5+ Rf5 57.Qd8+ Rf6 position Black close to lost, but the tension remains in position, and in infinite time anything is possible.
54.Rxg7+ Kh6 55.h4! Clear the final point. Black resigned.
