Courage seen in never moving king, queen, or rook (5)
I believe the answer is:
nerve
'courage' is the definition.
(nerve is a kind of courage)
'in never moving king queen or rook' is the wordplay.
'never' anagrams to 'NERVE'.
However, I'm unsure how this is indicated.
'seen' acts as a link.
Can you help me to learn more?
(Other definitions for nerve that I've seen before include "Fearlessness" , "Body fibre conveying sensations to brain" , "Fibre carrying impulses from brain to body" , "Dangerous type of gas" , "Cheek; self-possession" .)
