R Praggnandhaaa, the mind-work and legwork involved is the kind of life he loves living. Who would complain if the incentive of all that comes in the form of checkmating the world champion? World number one Magnus Carlsen, number 10 Anish Giri and number 22 Wei Yi are names who recently found it tough to read the mind of India's chess wizkid Rameshbabu Praggnandhaa, 'Praggu' to his close ones. At the Chessable Masters last week, he beat all of them in the knockouts, before taking the battle in the final against world number two Ding Liren down to the wire. The Indian genius lost the title-clash in the blitz tiebreak. Soon after that, close to the wee hours of the morning, the next thing on Praggu's mind was his 'Computer Application' examination at school in a few hours.
