In a remarkable achievement, Singapore's eight-year-old Ashwath Kaushik made history by defeating 37-year-old grandmaster Jacek Stopa in a game of classical chess. Kaushik became the youngest to defeat a grandmaster, a record set by Leonid Ivanovic from Serbia just days earlier. Despite being a Singaporean, Ashwath was born in India and has been living with his family for six years in Singapore. But is Ashwath the first to beat a grandmaster at such a young age? Who are the other youngsters to have beaten grandmasters? And how does he measure up to someone like R Praggnanandhaa? Rupha Ramani gives you all the answers.
