(Reuters) - An eight-year-old became the youngest player to defeat a grandmaster in classical chess on Sunday when Ashwath Kaushik beat Poland's Jacek Stopa at the Burgdorfer Stadthaus Open in Switzerland.

Indian-born Ashwath, who lives in Singapore, defeated 37-year-old Stopa to break the record set a month earlier by Leonid Ivanovic from Serbia when he beat grandmaster Milko Popchev, according to the Chess.com website.

Ivanovic is also aged eight but was born five months before Ashwath.
