Wijk Aan Zee (The Netherlands): World champion Viswanathan Anand mishandled a winning endgame and drew with former women's world champion Yifan Hou of China in the 11th round of 75th Tata Steel Chess tournament here. Desperately needing a victory to bridge the gap with tournament leader Magnus Carlsen of Norway, Anand outplayed Yifan right from the opening but a shocking blunder in what appeared to be a winning position cost the Indian an important half point.
Carlsen remained in sole lead after surviving some anxious moments against Wang Hao of China who pressed for a victory against the world number one. The Norwegian took his tally to 8.5 points out of a possible eleven and he is now trailed by Levon Aronian of Armenia who defeated Hikaru Nakamura of United States. With Aronian on 7.5 points, Anand slipped to sole third spot with seven points in all and now the chances of world champion catching up with tournament leader are absolutely slim.
In other games of the day, P Harikrishna enjoyed a superior endgame but could not convert it in to a full point against Erwin L'Ami of Holland. Another draw took Harikrishna to a respectable 5.5 points in the category-20 super tournament. The day featured four decisive games in all and reaping rewards was Sergey Karjakin of Russia who defeated Ivan Sokolov of Holland. Another Dutch Loek Van Wely went down to Peter Leko while local star Anish Giri demolished the defenses of Fabiano Caruana of Italy to register his first victory in the tournament.
Desperately needing a victory, Anand outplayed Yifan right from the opening.
With just two rounds to come, the tournament looks of academic interest with Carlsen having a full point lead. Anand meets L'Ami in the next round and will be hoping for an improved performance. It was a Najdorf Sicilian by Anand as black and Yifan went wrong early while trying to launch an offence against the centralised black king. Anand neutralised the initiative and post the trading of queens enjoyed a decent advantage.
A further error by Yifan left her a pawn less and immaculate manoeuvres by Anand quickly led to a winning knight and pawns endgame. However, with the win in sight, Anand made an optical error and found himself in a drawn king and pawns endgame. Harikrishna also should have won against L'Ami but his technique did not come good in the ensuing minor pieces endgame. L'Ami held his fort together and salvaged a half point.
