Early on, moves on board to generate opportunity (7)
I believe the answer is:
opening
'opportunity' is the definition.
(I know that opening is a type of opportunity)
'early on moves on board' is the wordplay.
'early' says to take the initial letters (I've seen 'earliest of' mean this).
'moves on board' becomes 'pening' (I can't explain this - if you can you should believe this answer much more).
The initial letter of 'on' is 'o'.
'o'+'pening'='OPENING'
'to generate' acts as a link.
Can you help me to learn more?
(Other definitions for opening that I've seen before include "- - time (pub)" , "Initial" , "First -- beginning" , "launch" , "Kicking off" .)
