CHENNAI: The ongoing lockdown has been a boon to a few who have finished their pending jobs while others have begun new chapters in their life. Grandmaster SP Sethuraman belongs to the first category while his good friend - GM B Adhiban - falls into the second.While Sethuraman has given final touches to his maiden book, Adhiban is taking the first steps in becoming an author.Almost six years after GM Parimarjan Negi wrote a book on chess openings, Sethuraman too has written on the same aspect of the game. Playing tournaments round the year made it difficult for the 27-year-old to give that extra time for his first book. But the current lockdown allowed Sethuraman to wrap up the book from his end.“I was approached by Thinkers Publishing , based out of Belgium, last year to write this book specifically on openings. I was hesitant since it is a time-consuming exercise but chose to still go with it,” Sethuraman told TOI.During the course of penning the book, Sethuraman managed to take tips from Negi on how to go about the whole exercise. “He shared with me some clues which came in handy,” said Sethuraman.He now joins the list of chess players who have gone on to get published. The book, titled “Play 1.e4! - A Complete Repertoire For White Against Najdorf & Taimanov” takes a holistic look at the openings in the game. Sethuraman feels players with varied ELO ratings will benefit from his work. “Openings are one of the most important aspects of the game and each player gives a lot of weightage to it. We have given a lot of analysis which will benefit players of all categories. It has been a great learning experience for me as well,” said Sethuraman.While Sethuraman has laid emphasis on openings, Adhiban’s book will focus more on middle and end games. “I am still in the process of deciding how I will go about the whole thing. But yes, becoming an author is something I always wanted and the last few weeks have given me the time to work on it,” he said.
