According to organisers, Anand, who is a special guest at the ICM, will simultaenouly take on 40 mathematicians from across the globe in a game of chess.
Anand is embroiled in a controversy over his citizenship after the University of Hyderabad had delayed its plan to confer an honorary doctorate on him following questions raised by the Union Human Resourses Development Ministry over the chess wizard's nationality.
Although he holds an Indian passport, the HRD Ministry raised questions on Anand's nationality because he lives in Spain.
Upset with the HRD's ministry's view on his nationality, Anand today declined to accept the honour at least for now.
