Good opening with scope for clever move on board (6)
I believe the answer is:
gambit
'clever move on board' is the definition.
I can't judge whether this definition defines the answer.
'good opening with scope' is the wordplay.
'opening' suggests taking the first letters.
'with' means one lot of letters go next to another.
'scope' becomes 'ambit' (synonyms).
The first letter of 'good' is 'g'.
'g'+'ambit'='GAMBIT'
'for' is the link.
Can you help me to learn more?
(Other definitions for gambit that I've seen before include "Tactic intended to gain an advantage" , "Opening action" , "tricky move" , "in school scrap" , "Tactical move" .)
