Viswanathan Anand of India retained his world chess title Tuesday by winning with black against Bulgarian challenger Veselin Topalov. The score was 5.5-5.5 before the last game. Each player needed only one win to secure the match. Anand's 56-move win came in the last of a possible 12 games between the two, allowing the 40-year-old Indian grandmaster to retain the title he won in 2008. Anand lost the first game against Topalov but quickly recovered to drew level in the second. The Indian won the fourth game and took a one point lead before Topalov stroke back for a second time in the eighth game. The remaining games ended in draws. Topalov, 34, won the right to challenge Anand after a 4.5-3.5 victory last year over Gata Kamsky of the US. A purse of 2 million euro (US$2.56 million) is to be split between Anand and Topalov.
