Expert at managing men on board? (11)
I believe the answer is:
grandmaster
'board?' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's a link between them I don't understand?
'expert at managing men' is the wordplay.
'expert' becomes 'master' (master is a kind of expert).
'at' means one lot of letters go next to another (I've seen this in other clues).
'managing men' becomes 'grand' (I can't justify this - if you can you should believe this answer much more).
'master' put after 'grand' is 'GRANDMASTER'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for grandmaster that I've seen before include "Senior chess player - senior mason" , "Chess player of the highest class" , "A top chess player" , "Expert on board" , "Exceptional player" .)
