Nigel has CERTAINLY heard of Dommaraju Gukesh.
From my Guardian column of 20 April this year:
What occurred to Nigel Short at the Bangkok Open this week was much worse. The former world title challenger is a regular at Thailand’s annual event, won it in 2017, began this week with 3.5/4, and as the No 2 seed looked set for a strong performance. In round five Short steadily outplayed India’s youngest and newest IM, 11-year-old D Gukesh, and reached a won ending two pawns up.
Then, disaster. Short gave a rook check, forgot to press his clock and after a few minutes his flag fell. He wrote on Twitter: “Lose with dignity … is a bit hard when your opponent is fully aware that you have not pressed your clock and jumps up and down with glee the moment your flag falls.”
