Just noticed this, chrise@1. Thanks. Quite specialist for a general cryptic, needing to know chess notation and the starting squares for pieces. I have added it to a thread I started in November 2020 on the English Chess Forum entitled 'Times Cryptic Chess Clues', though other newspapers have provided examples too.
I started the thread with a clue which I also thought quite specialist, though Chambers does have the definition.
