My response of c5 d7 to his e4 c5 was to indicate a knight's move on an open board, no other pieces, and to let him know that he was on the right lines, that's if, indeed, he was talking about chess and not something else.
His reply about "Fairies and fu-aad" confirmed he knew it was about chess, that's after I'd looked them up.
Riddle:
Curse that Sicilian, he has forced me to change my position, a move most disadvantageous to me.
"Sicilian" a clue to indicate "Sicilian defence" a term used in chess.
But underquark has not resolved the riddle yet.
