An invasion of insects sparked losing errors from Ian Nepomniachtchi against Wesley So in their semi-final
An invasion of mosquitoes defeated Russia’s world title challenger Ian Nepomniachtchi on Friday evening when his online opponent, the US champion Wesley So, was only looking for a draw.
It was the first four-game set (of two) of a semi-final between the grandmaster pair. They had drawn the first three, and it seemed the match would go into Saturday’s second session at 2-2. The other semi-final between Magnus Carlsen, the world champion, and Teimour Radjabov, of Azerbaijan, was level before a two-day final on Sunday and Monday.
