Six players with mathematical chances to take home the title

Six players remain in contention for first place going into the final round of the Women's Candidates Tournament. Bibisara Assaubayeva and Vaishali Rameshbabu share the lead on 7½/13 after Assaubayeva defeated Anna Muzychuk with the white pieces, while Vaishali survived a difficult position against Tan Zhongyi to secure a draw.

Zhu Jiner, who entered the round tied for first place with Vaishali, missed an opportunity to move into sole first place and even went on to lose against Aleksandra Goryachkina, while Kateryna Lagno stayed in contention by defeating Divya Deshmukh.

Assaubayeva was the main beneficiary of the round. Having been a half point behind the leaders before the round, she now enters the final day level at the top after scoring her third win in the last four games. Her tournament had appeared to be slipping away after back-to-back defeats in rounds five and six, but she has responded strongly in the closing stages.

Round 13 results

Assaubayeva's game against Muzychuk began in ideal fashion for the Kazakh GM.She used very little time in the opening and by move 13 had already reached a position that was both pleasant and free of significant risk.

An exchange of knights on d5 left Muzychuk under pressure, and before long Black had little choice but to part with a pawn.

Although Assaubayeva remained in control for most of the game, the path to victory was not completely straightforward. There were moments when Muzychuk might have been able to hold the balance, but an inaccuracy with 32...a6?, proved decisive.

Assaubayeva was then able to create a passed b-pawn, leaving Muzychuk unable to defend weaknesses on both wings at once. Muzychuk still has a slim chance of winning the tournament, but now trails the leaders by a full point.

Vaishali, who had started the round as co-leader, retained her share of first place thanks to a resilient defensive performance against Tan Zhongyi. The Indian grandmaster found herself under pressure for long stretches and needed to defend accurately to secure the draw. The half-point was enough to keep her at the top.

Zhu Jiner came close to emerging as sole leader, but instead suffered a painful defeat against Aleksandra Goryachkina. The game had initially developed in her favour, and at one stage Zhu held an extra pawn in a promising position.

Earlier in the game, Goryachkina would have been content to force a draw by repetition on move 27, but Zhu chose to continue playing in search of the full point. For a while, that decision appeared justified, as she maintained the initiative. However, the presence of Goryachkina's outside passed pawn ensured that the game always remained dangerous.

The turning point came suddenly when Zhu made the serious mistake 51.Re5?, after which Goryachkina found the precise defensive resource 51...Kh8

From that moment, the evaluation changed completely, and Goryachkina converted the advantage to score an important victory.

Kateryna Lagno's win over Deshmukh means she also remains in the race going into the final round. Her tournament has followed a curious pattern, as every decisive result has been followed by a return to an even score. Three times she moved to plus one and immediately lost the next game, while after dropping to minus one in round twelve, she immediately bounced back with a win.

Against Deshmukh, Lagno dominated from the outset and steadily overwhelmed her opponent's position.

Deshmukh has endured a difficult finish to the tournament. Since defeating Muzychuk in round eight after escaping from a lost position, she has lost four of her next five games.

The final round is set up for a tense finish. Vaishali, who will have white against Lagno, and Assaubayeva, who will have black against Deshmukh, both control their own fate: a win would guarantee at least a playoff for first place. Zhu can still catch the leaders with a victory if either of them only draws. There also remains the possibility of an even larger tie at the top if several of the chasing players win.

60m English New ideas in the Najdorf_E

‘New ideas in the Najdorf – a Power Play 18 Update’ aims to complement Daniel King’s popular DVD from last year ‘The Sicilian Najdorf - a repertoire for Black’. Such a dynamic and popular opening as the Najdorf is developing the whole time. On this download, Daniel King updates lines that were included on his DVD but also responds to viewers’ requests, considering lines that he omitted from his original repertoire. The lines examined on this update are: • 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 6 h3 e5 7 Nde2 • 5….a6 6 Bc4 in combination with the English Attack (Be3, f3 etc) • 5…a6 6 Be3 and the …a5 variation • 5…a6 6 Be2 and 9 Re1 • 5 f3 (instead of 5 Nc3) It isn’t necessary to have seen the original Najdorf DVD to understand the lines examined here – but it would help as they form part of a complete repertoire.
