It’s “the Indian earthquake in Toronto”, said Russian chess legend Garry Kasparov as he lauded teen Grandmaster D Gukesh for becoming the youngest ever challenger for the world title, a triumph which marks the “shifting tectonic plates” in the game’s global order.

Gukesh, 17, bettered the record created by none other than Kasparov 40 years ago. The Russian was 22 when he qualified in 1984 to clash with compatriot Anatoly Karpov, making him the youngest challenger of that time.
