Comments by GM Vitaly Kiselev
This game was played by the World Champion Title runner-up and the
Russian Champion. Both opponents won in the previous rounds and would be
glad to continue playing in the same way. They played Slav Defense, but
White chose not a very principle continuation having played cd and
maintained a rather stable position that looked like exchanged Slav
Defense. This tournament the Indian chess player prefers to chose
peaceful positions without complications. The game turned out to the
position with opposite castlings with a little better black pawns
structure. White decided to maintain the dynamic equality by taking a
pawn, but Black managed to force the draw by repeting the position that
was actually done in the game. As Alisa Galliamova confessed at the
Press Conference: "To draw the game with Koneru playing Black is a good
The game between the two leaders drew a special
attention of the fans. They played a Spanish Defense (Marshall Attack)
that can be applied only possessing appropriate theoretical knowledge.
We could see that Anna Muzychuk was perfectly prepared, however after
15.Qе2 she took time to think over for the first time and, as she
confessed later, this variation was not studied thouroughly. That is why
she missed the opportunity to force the draw that was possible after
17...Nf4. The Chinese chess player was precisely defending and the 25th
move turned out to be decisive when Muzychuk let her opponent exchange
rooks and convert the game to a technically winning endgame.
Tatiana Kosintseva - Elina Danielian
This time the Armenian chess player playing Black had to face the younger sister of Kosintsevs. Elina Danielian repeated the opening by playing Caro-Kann Defense. Tatiana played 4.Се3 in the closed varition and did not repeat the variation from the game of the 1st round of Nadezhda where the latter played Nd2 against Elina. Black played the typical for such positions plan and moved the Knight first to h6 and then to f5, where White exchanged this Knight. Black remained with doubled pawns on "h" file, but received the two bishops advantage as compensation. Elina Danielian has implemented a very strong cplan by moving her bishop from g7 to c5; the bishops became strong and Black received an obvious advantage. Then Black managed to double the rooks along the second line but they missed the opportunity to get an advantage by exchanging two rooks for a queen. As a result Elina Danielian made a mistake and after the time control they got a drawish rooks endgame.
Lufei Ruan - Ekaterina Kovalevskaya
Ekaterina Kovalevskaya was very firm and played Sicilian Defense. Ruan Lufei played 3.Bb5 variation and sharpened the position by sacrificing a pawn. They received an unusual position with a strong Black pawns center and White's activity. The Russian chess player had problems with King's position and already by the 20th move her time was getting over. She started playing faster and did not find defending moves. After the time-trouble they got the Knight endgame 2 against 1 pawns on the King's side. By their precise play Black themselves ensured a draw.
Antoanetta Stefanova - Alexandra Kosteniuk
The Queen's Indian Defense with the move 4.Cb4 was played in the game. Antoaneta Stefanova defended from the check by the means of the Knight instead of a more popular bishop defense. An interesting pieces battle developed on the chess board, Black got an advantage due to the weakness of the pawns structure on the White's king side, however, instead of the problematic 35...Qd7 Black played 35...Qe7, White managed to beat off the Black's attack by the precise defense. After the queens exchange they faced the endgame where White had better chances, but after the precise play from both sides the game was drawn.
Kateryna Lahno - Nadezhda Kosintseva
White chose Reti's opening, but finally they received a non-standard position that looked like Catalan opening. The game developed in a very interesting fight; exchanges followed closer to the time-trouble and after the control they received the endgame with opposite color bishops. The material advantage (Black had an extra pawn) did not play a big role and was not so important due to the white piece's activity. In the time-trouble Black started playing inaccurately and got a worse position. At the end of the second time control Black made another mistake and had to defend worsee endgame. White managed to win by playing precisely in the ending.
