Talks about daughter and son's rapid search for mates (5,5)
I believe the answer is:
speed chess
'mates' is the definition.
Both the definition and answer are singular nouns.
I also know that 'mates' relates to this answer.
'talks about daughter and son's rapid search' is the wordplay.
I cannot quite see how this works, but
'about' could be 'c' (circa) and 'c' is found within the answer.
'daughter' could be 'd' (genealogical abbreviation) and 'd' is found in the answer.
'son's' could be 'ss' (genealogical abbreviation for son) and 'ss' is located in the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for speed chess that I've seen before include "which leaves little time for mate" , "movement of men with expedition" , "attempt to mate quickly" .)
