An “extraordinary” moment in Gukesh-Ding WCC Game 13 and knight-switching proof games
18 Dec. 2024
During Game 13 of the World Championship match between Gukesh and Ding, I was watching the livestream on Chess24 where the commentators (both terrific) were GM Peter Leko and GM Daniel (Danya) Naroditsky. When Gukesh played 15.Sh5 (see diagram below), an eagle-eyed Leko pointed out that this knight on the right-edge came all the way from b1 while the knight standing on c3 originated from g1. The two commentators were amused as well as amazed by such an unusual occurrence, with Leko calling it “extraordinary” and Danya saying his mind is blown. As a problemist I was reminded of certain proof game compositions where two equivalent pieces must paradoxically switch places, to attain a position as quickly as possible. Then to my surprise Danya expressed a similar thought.
