The eleventh round of the world Junior championship in review of international master Vladimir Barsky.
Leader Jan-Krzysztof Duda from Poland did quite calm Black tie with the German Junior Matthias Blobaum and the gap from him to half points reduced Francesco Rambaldi (Italy) and Mikhail Antipov (Russia).
Rambaldi – W. Bajarani
Black too risky played in the opening and had to give up the quality. And then began a kind of game of “cat and mouse”: sometimes the computer evaluated the superiority of the White “+10″, but Francesco could not strike a decisive blow.
It was time to open a “second front” on the Queenside: 33.Rxb4! axb4 34.g7+ Ke8 35.Qxb4 Qe7 36.Qb6!, and Black has no defence against Bg6+; for example: 36…fxe5 37.Bg6+ Kd7 38.Qxb7+ and 39.Qxb8.
33.Qh7 Qg7 34.Nf3 b6 35.Rg4 Bd7 36.Rh4 Rd8 37.Nd4
Francesco, there are several straightforward – trying to break through the center, and it was necessary again to draw their attention to the Queenside: 37.c3! Bc5 (b6 pawn can’t be given) 38.Qxg7+ Kxg7 39.Rh7+ Kf8 40.Bb5!, and after exchanging light-squared Bishops in Black no one will hold the checkpoint pawn “h”.
37…f5 38.Bb5 Bxb5+ 39.Nxb5 Rd7 40.Nd4 Rd6 41.c3 Bc5 42.Re1 Bxd4 43.cxd4 Rc6 44.Qh5 Ne7 45.Qg5 Qxg6 46.Qf4
It was a beautiful way to victory: 46.Rh8+ Kg7 47.Qh4 f4 48.Rh6! Qxh6 49.Qxe7+ Kg6 50.Qe8+.
46…Qg7 47.Rh5 Kf7 48.Qh4 Ng6 49.Qg3 Nf8?
Azerbaijani grandmaster ingeniously defended, and after 49…b5! 50.Qb8 Kf6 got real chances for a draw. White cannot take the pawn (51.Qxb5? Nf4), direct ways to strengthen the position not visible, but Black already appears counterplay. But at this point Ulvi missed an easy shot.
50.Rxf5+! exf5 51.Re7+ Kxe7 52.Qxg7+ Ke8 53.Qe5+ Ne6 54.h4, and Black soon resigned.
Antipov – M. Chyhayev
Russian Derby on the third table. In roughly equal positions Mikhail Antipov better disposed of the figures and “preministerial” his opponent.
Black there to win a pawn with 28…f6 29.Qc2 fxe5, but after 30.Nd2 White has good compensation through control of White spaces and Black has also a weak King. But in order Maxim Chigaev was another interesting maneuver – 28…Na6!? In the case of exchange of Queens Black’s chances, perhaps, preferable White needs to spend some momentum to bring the Rook into the game. If the Queen moves – 29.Qb2,…Nb8 29, and the Knight in a roundabout way come to d7 increase the pressure on the E5 pawn.
The idea is the same – getting rid of the cords, to guide the Knight to d7. But here White has the opportunity to improve the position of his pieces.
29.Bc4 Rd1+ 30.Kh2 Qd8 31.Qe3 Qc7
Deserved attention waiting move type 31…Kf8, not allowing White to intensify the Knight.
32.Nd4 Qd8 33.Nc6
Objectively the position is about equal, but from repetition of moves (33.Nf3) Antipov dodges.
33…Qd2 34.Rh3 Qc2 35.Rh4 Qb1 36.Rd4
Serious threats to the King of h2 is not new, and White, meanwhile, had returned to the Rook in the center and took an open line. A little bit Antipov accumulates positional advantages.
36…Rh1+ 37.Kg3 h5 38.Bd3 Nxd3?!
Perhaps the first serious inaccuracy. Active Knight was better to save and play 38…Qc1.
39.Rd8+ Kh7 40.Qe4+ Kh6 41.Qe3+ Kh7 42.Qxd3+ Qxd3+ 43.Rxd3
Not there, the E5 pawn is much more important! After 43…Kg6! 44.Rd7 Re1 45.Ne7+ Kh7 46.f4 Bh6! Black has sufficient counterplay. Now Antipov technically overtaKing opponents.
44.a4 Bf8 45.Rd7 Kg6 46.Nd8!
Maybe Black was counting on 46.Rxa7 Bc5 47.Nd8 Bd4 48.Nxf7 Kf5!, and they have, despite the absence of two pawns, excellent counter chances. Move in party for them is much more unpleasant.
The decisive error. Much harder 46…Rf1! 47.Rxf7 Bg7 48.Rxa7 Bxe5+ 49.Kf3 h4 with good chances for a draw.
47.f3 Bb4 48.Rxf7 Be1+ 49.Kh3 Rb4 50.g3 h4
Not saved and 50…Rxa4 51.Rf6+ Kh7 52.Nxe6.
51.Rf6+ Kh7 52.Rf4 Black resigned.
Goryachkin – E. Bogdanov
After an unsuccessful tournament cut again pleased their fans Aleksandra goryachkina. The champion of Russia outside the box played White against the King’s Indian defense and has made a large material advantage. The opponent rushed in a desperate counterattack, but he coolly reflected all threats.
29.Bd2! Qh2+ 30.Kd3! Ne5+ 31.Kc2 Qe2 32.Rad1 Ba6 33.Qxc7+ Kg6 34.Qxd6+ Bf6 35.Rge1 Bd3+ 36.Kc1 Qg2 37.c7 Be4 38.Qxe5! Black resigned.
In the girls tournament second defeat in a row suffered Zhansaya Abdumalik is in a difficult position missed a powerful blow to the opponent.
Abdumalik – D. Derakshani
Iranian chess player has chosen for such an important meeting gambit of Anisha and leaving the King in the centre, pumped threats on the Kingside. Of course, Zhansaya was able to exchange Queens and fully to protect yourself from all the trouble, but after 30.Qg2 Qxg2+ 31.Kxg2 White and if there are overweight, it is symbolic – a little more space. And revealing the shortcomings of building Black allowed preventive maneuver 30.Qf2! Raf8 31.Rfb1!, and the approaching Black comes to a standstill, as the g5-g4 (immediately or after sacrifice on f3) White 32 helps.Bf1 with the capture of the Queen.
If Black 30.Qf2! answer 30…g4, then after 31.f4! exf4 (bad and 31…Nxf4 32.gxf4 Rxf4 33.Qg3) 32.e5! Whites were the first to begin the attack, and she turns out to be very dangerous.
30.Rf2?! g4! 31.f4 Nxg3!
A great solution! For the Knight get Black while only two pawns, but soon takes a third, and a fourth… And most importantly – they have now a very easy game.
32.hxg3 Qxg3+ 33.Rg2 Qc3 34.Re1 Rxf4 35.Qe3 Qxb4 36.Rb1 Qxa5 37.Rxb7 Qa1+ 38.Kh2 Qd4 39.Qg3 Raf8 40.Qh4+?!
New inaccuracy control on the go. Immediate 40.Qb3 bad for 40…Rf2; but he saved 40.Be2! h5 (the Knight can’t take: 40…Qxd2? 41.Rxd7+!) 41.Qh4+ R8f6 42.Qg5 or more thin 40.Kh1! (the idea is that after Rf2 capture on g2 will happen without the Shah, and White wins an important tempo to create counterplay) 40…R8f6 41.Qb3 h5 42.Rxd7+! with a draw.
40…R8f6 41.Be2 Kd8 42.Ba6 Rf2
And here White rescued tricky waste 43.Kh1!, for example: 43…Qe3 44.Rxf2 Qxf2 45.Qxf2 Rxf2 (without the Shah.) 46.Nc4 Ra2 47.Nb6 Be8 (or 47…Rxa6 48.Rxd7+ Ke8 49.Rb7) 48.Rb8+ Ke7 49.Nc8+ Kf6 50.Bc4 Rd2 51.Nxd6 White-balanced.
43…Rxg2+ 44.Kxg2 Qxe4+ 45.Kg1 Qd4+ 46.Kg2 Qf4 47.Rb2 Ke7 48.Rf2 Qxf2+ 49.Qxf2 Rxf2+ 50.Kxf2 d5
Five pawns for a Knight is too much.
51.Kg3 Kf6 52.Nd2 Kg5 53.Nb3 h5 54.Nc5 h4+ 55.Kg2 Bf5 56.Bb7 Be4+
In the case 57.Nxe4+ dxe4 58.Bxc6 Kf4 Black also won, for example: 59.Bb5 e3 60.Be2 h3+ 61.Kh2 e4 62.Bd1 g3+ 63.Kxh3 e2 64.Bxe2 Ke3 65.Kf2 Bf1 66.Bg2 e3 – one of the pawns is held in Queens.
57…g3+ 58.Kh3 Bf5+ 59.Kg2 Kg4 60.Bxc6 h3+ 61.Kg1 62 d4.Nb3 63 d3.Nd2 Kf4 64.Nc4 e4 65.Nb6 Be6 66.Na4 e3 67.Nb2 Bf5 White resigned.
Zezulkina – A. Bivol
Alina Bivol came out of the opening by a margin, but then yawned simple and nice tactical shot.
After careful 23…Qa6! White can play 24.Bc3 because after 24…Bxc3 25.Qxc3 Ra3 26.Qc2 Bxh3! remain without pawns. However followed
23…Re8? 24.Be3! fxe3
We have to give quality, as after 24…Qa6 25.Rxa2 Qxa2 26.Bd4 (with the threat of capture of the Queen) 26…Bxd4 27.Nxd4 Qa6 28.Ra1 Qb6 29.Qc3 Black has a very bad position.
25.Rxa2 exf2+ 26.Rxf2 Ng6 27.Bc2 Nf4 28.Qe3
Practical solution: give White a pawn, but the exchange of Queens.
28…Nxd5 29.Qxb6 Nxb6 30.Ne3 Be6 31.Rd2
The pawn was better to leave in place, but after an approximate 31…Bc3 32.Rdd1 Bd7 33.Nd4 play White much easier here – quality is quality. Although, of course, the chances for a draw here Black large, they need only to somehow “absorb” their Knights.
32.Rdd1 Nc4 33.Nxc4 Bxc4 34.Ra1 Rb8 35.Nd4 Nd8 36.Ra6 Bxd4+ 37.Rxd4 Nf7 38.Ra3
The C3 pawn is lost, and White’s position becomes technically won.
38…Kf8 39.Rxc3 Ra8 40.Rd1 Ke7 41.Bd3 Ne5 42.Bxc4 Nxc4 43.Rd5 Ra1+ 44.Kh2 Rb1 45.e5 dxe5 46.Rxb5 Nd2 47.Rc6 Nf1+ 48.Kg1 Ng3+ 49.Kf2 Ne4+ 50.Ke3 Nd6 51.Rbb6 Rb3+ 52.Kd2 Ne4+ 53.Kc2 Rg3 54.Rb7+ Kd8 55.Rxh6 Black resigned.
Leader Natalia Buksa (Ukraine) played a draw with Russian Alexandra Makarenko and now a whole point ahead Zhansaya Abdumalik of Kazakhstan) and Natalia Zezulkina (Belarus). Ahead of two decisive rounds.
