Tamas Fodor — Michael Adams, Hull 2018. White to play. One from the puzzles section of Smerdon’s book, which I witnessed myself. Adams’s last move, 60…Kf6-f7 set a trap. White’s next was a queen move that walked right into it. What was the losing move? Email answers to chess@spectator.co.uk by Monday 1 June.
