Growing expert of women chess, as you can remember his reports and comments during the World Women Team Championship, 2012 European Womens Individual. Also 2012 Chess Olympiad and many others. Evgenij is going to provide us with analysis of the most interesting moments happened in the games during the WJCC as well.

You can follow his comments below;

Today’s report was literally made “on a go”, so it doesn’t contain a lot of talking, but a few commented games from the leading group instead.

Yu, Yangyi (2662) - Salem, A.R. Saleh (2570) [C45]

The principle battle, after which we finally got the sole leader in the tournament. 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Bb4+ 5.c3 Bc5

1

The main point of "losing a tempo" on a previous move is to deprive white's knight from the most natural square it opts for. The line wasn't the main theoretical trend whatsoever, but has been played on rare occasions by as strong players as Adams, Bacrot and Aronian to name the few. 6.Be3 Bb6 7.Nf5 g6 8.Bxb6 axb6 9.Ne3 Nf6 10.f3 Qe7 11.c4 Qb4+ 12.Qd2 Qxd2+ 13.Kxd2

2

Resulting endgame is somewhat better for White, although Black's position remains quite solid. 13...d6 14.Nc3 Kd8 15.Be2 Preparing slow regroupment of White's forces as Black has difficulties finding a counterplay. [Black doesn't seem to have a lot of trouble after 15.f4 Re8 16.Bd3 Nb4 17.Bb1 Nd7 18.Ned5 Nxd5 19.cxd5 Nc5 20.Bc2 f5 21.exf5 Bxf5 22.Rae1 Rf8 23.g3 c6 24.b4 Na6 25.dxc6 bxc6 26.b5 cxb5 27.Bb3 Nc5 28.Nxb5 Kd7 29.Nd4 Be4 30.Rhf1 d5 31.h4 Nxb3+ 32.axb3 Ra2+ 33.Kc3 Rc8+ 34.Kb4 Rc5 35.Rc1 Rd2 36.Rcd1 Rb2 37.Rc1 Kd6 38.Rfd1 Rg2 39.Nb5+ Kc6 40.Nd4+ Kd6 41.Nb5+ Kc6 42.Nd4+ 1/2 Wang Hao (2743)-Aronian,L (2813)/Stavanger NOR 2013/ 15...Re8 16.Rac1 Nd4 17.Rhd1 c6 18.Bf1 Kc7 19.Ke1 

3

19...Ne6 There's nothing wrong with this move, but knowing how terribly squeezed Black had been in the present game, I'd recommend [19...Nf5! for those who's going to look for improvement in this line - 20.Nc2 Nd7 21.Kf2 Ne7 preparing to start counterplay with f7-f5 under a bit more favorable circumstances compared to the game.] 20.b4 Nd7 21.Kf2 Ng7 22.Rd4 f5 23.a4

4

23...Nf6?! Strange decision, as [23...f4 24.Nc2 Ne5 looks much more natural to me.] 24.Rcd1 Re6 25.g3 fxe4 26.Bh3 Re7 27.Rxd6!? This starts an interesting tactical struggle, in which White eventually manages to get an upper hand. 27...Nge8! [Bad would've been 27...Bxh3? 28.Rxf6 Bd7 29.Ned5+! cxd5 30.Nxd5+ Kd8 31.Nxe7 Kxe7 32.Rxb6 with huge advantage for White.] 28.Rd8 exf3 29.b5 Black is paralyzed and has to look for the way to crawl out with his pieces. 29...Rb8?! [29...Re5!? , intending to play Rh5, would've been an interesting try. After 30.a5 bxa5 31.c5!? (After 31.b6+ Kxb6 32.Rxc8 Rxc8 33.Bxc8 33...Kc7! 34.Bh3 Rh5 35.Bf1 Rxh2+ 36.Kxf3 Nd6 Black seems to have fair chances to get out of trouble.) 31...Rxc5 32.b6+ Kxb6 33.Na4+ Ka7 34.Bxc8! position is rather unbalanced.] 30.a5 [30.c5 bxc5 31.b6+ Kxb6 32.Rxc8 Rxc8 33.Bxc8 Ka5! doesn't seem to be clear either.]

5

30...Nd7? A blunder. Perhaps Black went too optimistic about his position and thought this way he's going to win material, but the move is so "ugly looking" that I do believe it simply has to be something for white! [The correct 30...bxa5 31.b6+ Kxb6 32.Rxc8 Rxc8 33.Bxc8 Kc7 34.Bh3 Nd6 would still keep the tension as Black certainly has compensation for the piece, at least in terms of a practical game.] 31.Rxc8+! Kxc8 [Even worse is 31...Rxc8 32.Ncd5+ cxd5 33.Nxd5+ Kb8 34.Nxe7+-] 32.Ned5! cxd5 33.Nxd5 Rg7 [33...Re2+ 34.Kxf3 Rxh2 35.Nxb6+ Kc7 36.Rxd7#] 34.Nxb6+ Kc7

6

35.Nxd7 Now it's all over as black king can't escape the mating net. 35...Ra8 36.b6+ Kc6 37.Rd5 Rxa5 [37...Re7 38.Ne5+ Rxe5 39.Bd7#] 38.Rxa5 Rxd7 39.Bxd7+ Kxd7 40.Kxf3 1–0

Eliseev, Urii (2550) - Bai, Jinshi (2412) [C80]

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0–0 Nxe4 6.d4 b5 7.Bb3 d5 8.dxe5 Be6 9.Nbd2 Nc5 10.c3 d4 11.Bxe6 Nxe6 12.cxd4 Ncxd4 13.a4

7

13...Bb4 [13...Bc5 14.Ne4 Bb6 15.axb5 axb5 16.Rxa8 Qxa8 17.Nxd4 Qxe4 18.Nxe6 fxe6 19.Be3 Bxe3 20.fxe3 Qxe5 21.Qf3= Vachier Lagrave,M (2703)-Ivanchuk,V (2764)/Warsaw 2010/] 14.axb5 Nxb5 15.Qa4 c5?! This sets Balck's bishop a bit out of play, so I'd say both alternatives are safer. [15...Be7; 15...Bxd2] 16.Nc4 0–0 17.Rd1 Nbd4 18.Nxd4 Nxd4 19.Be3 a5 20.Rac1

8

20...Rc8 [20...Ra6!? looks like an improvement on Black’s play, where 21.Bxd4 cxd4 22.Qc2 leads nowhere after 22...Qd5 23.Qd3 Rg6 24.Ne3 Qxe5 25.Qxd4 Qxd4 26.Rxd4 Rd6=] 21.Kh1 Qh4?! [Black could've escaped nasty pin on d file with the help of little tactical trick - 21...Qe7! 22.Bxd4 cxd4 23.Rxd4 f6 24.Qb3 Kh8 25.Re4 fxe5 26.f3 Rf4 , albeit the resulting position is still a bit unpleasant for a practical game.] 22.Nd6 Rcd8 23.Qa2! Now white queen joins the action, while Black's bishop is permanently stuck on b4. 23...Ne6 24.f4! Qe7 [Of course the pawn is poisoned - 24...Nxf4?? 25.g3! Qg4 26.Bxf4+-] 25.Qc4 Now all the White pieces are perfectly organized for a kingside attack, which was carried out in style by uprising russian talent. 25...Rd7 The worst thing about Black's position is the fact he can't afford any sensible counterplay, hence is doomed to passivity. 26.f5 Nc7 27.Qf4 Bringing the queen closer to the opponents king and intending to play f5-f6. 27...Rfd8

9

28.Qg3?! Not the most exact way as it allows some complications. [Straightforward 28.f6 would do the job a bit easier, as after the forced 28...Qf8 29.fxg7 Qxg7 white has a nice rook lift - 30.Rc4! , transferring the rook via the 4th rank with decisive effect.] 28...Ne8 29.f6 Qe6 30.Rf1 g6 31.Nf5 c4! Eventually getting the bishop into play! 32.h3 White had to slow down a bit, so Black obtains certain counterplay. 32...Rd3 33.Nh6+

10

 
33...Kh8? [Correct was 33...Kf8 , keeping f7 defended. The possible continuation would've been 34.Qf4 Rxe3! 35.Qxe3 Rd3 36.Qf2 (36.Qa7 allows 36...Rxh3+ 37.gxh3 Qxh3+ with perpetual) 36...Qxe5 and Black has enough compensation for the exchange so the position is balanced.] 34.Qf4? [Much stronger would've been 34.Qg4! where after 34...Qxg4 35.Nxf7+! Kg8 36.Nh6+ Kf8 37.Nxg4! brave knight does all the job! After 37...h5 38.e6! hxg4 39.Bh6+ Kg8 40.f7+ Kh7 41.Bg5 White is winning as e6-e7 is unstoppable.] 34...Rxe3? [All the fight would be in front after the correct 34...R8d7 - once again it was vital to defend the crucial f7 pawn. Instead Black went for a tactical operation which could've been nicely refuted by Eliseev, albeit in the game it wasn't that simple...] 35.Qxe3 Bd2 36.Nxf7+! Qxf7 37.e6?! Perhaps a time-trouble oversight, as [37.Qb6! and e6 on the next move would've finished the game at once!] 37...Qxf6
 
11
 
38.Qc5? [38.Qe2 was still good enough for an advantage, although after 38...Bxc1 39.Rxf6 Nxf6 40.Qe5! Rd1+! 41.Kh2 Kg7 42.e7 Kf7 43.Qxf6+ Kxf6 44.e8Q Bf4+ 45.g3 Rd2+ 46.Kg1 Bxg3 Black should be able to survive.] 38...Bb4? [Black could eliminate the main danger by 38...Qxe6 as 39.Qf8+ is not a checkmate (as, I assume, both of players were actually thinking)] 39.Qxc4 Qxb2? Decisive mistake. [Black's future would be much brighter after 39...Qe5 , intending Bd6. for instance 40.Rc2 Bd6 41.Qc3 Qxc3 42.Rxc3 Kg8 and it's only Black who can be better there.] 40.Qh4! Now White gets his pawn to e7, which proves to be too much for Black to cope with. 40...Rb8 41.e7 Qe5? Not the most stubborn, but at least it loses in the spectacular way. [41...Nf6! was the only chance to fight further, as the straightforward 42.Qxf6+ Qxf6 43.Rxf6 Bxe7 44.Rf7 Bd6 still offers Black some hope to survive.] 42.Rf8+ Kg7 43.Rcf1! h5 [Black could've tried 43...Qd5 where after 44.R1f7+ Qxf7 45.Rxf7+ Kxf7 46.Qf4+ Kxe7 47.Qxb8 Nf6 still some technic is required. I'd say White's king transfer to e6 would do the job in this case.]
 
12

44.Qg5! Not so much complicated but still nice little trick 44...Qxe7 [44...Qxg5 45.R1f7+ Kh6 46.Rh8#] 45.Qxe7+ Bxe7 46.R1f7+ Kh6 47.Rxe7 Rb1+ 48.Kh2 Nd6 49.h4! With mate in few moves to follow. 1–0

Bulmaga, Irina - Nguyen, Thi Mai Hung

An example from the girls tournament - nice schematic attack by Irina Bulmaga. 

13

19.h4! White has to hurry up to prevent Black's counterplay via c-file. 19...Nb6 [The radical method of fighting White's initiative on the kingside doesn't promise equality either - 19...f6 20.exf6 Qxf6 21.Qd2 followed by h4-h5 in the right moment should offer White better chances.] 20.Bg5 Qf8 21.h5 Nc4 22.g3 b5 Too careless. Black should've tried 22...h6 although after 23.Bc1 g5 24.b3 N4a5 25.Bc2! White is still much better. 23.Kg2 h6 Otherwise White is going to bring both rooks to h-file with deadly threats.

14

24.hxg6! fxg6 [24...hxg5 25.Nxg5 would transpose into the game.] 25.Bxg6 hxg5 26.Nxg5 Nd8 27.Qh5 Qe7 28.Rh1 Ra7 29.Rh4! Preparing rook's transfer to f4. 29...Nxe5 30.Qh7+ Good enough, but even stronger would've been [30.Re1 adding even more woods into a fire. Black's going to suffer huge material losses in order to avoid getting mated - 30...Nef7 (30...Nxg6 31.Qxg6 Qf6 32.Rh8+ Kxh8 33.Qh7#) 31.Bxf7+ Nxf7 32.Qh7+ Kf8 33.Nxe6++-] 30...Kf8

15

31.Rf4+ Nef7 32.Nxf7 Nxf7 33.Bxf7 Qxf7 34.Rxf7+ Rxf7 35.Re1 And White successful converted the advantage. 35...Rc6 36.Qh4 Bf6 37.Qh6+ Ke7 38.Qe3 Kd7 39.Re2 Rg7 40.f3 Re7 41.f4 Rc4 42.Rd2 b4 43.axb4 Rxb4 44.Qa3 Rb6 45.Qa4+ Kd8 46.g4 Reb7 47.g5 Bg7 48.Qa5 Ke7 49.f5 exf5 50.Re2+ Kf7 51.Qxd5+ Kg6 52.Kf3 Rxb2 53.Kf4 Bf8 54.Qg8+ Bg7 55.Re6+ 1–0
