Takes on expert grabbing 100 points (7)
I believe the answer is:
accepts
'takes on' is the definition.
('accept' can be a synonym of 'take on')
'expert grabbing 100 points' is the wordplay.
I cannot quite see how this works, but
'100' could be 'c' (Roman numeral) and 'c' is located in the answer.
'expert' could be 'ace' (ace can informally mean very good) and 'ace' is found in the remaining letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for accepts that I've seen before include "Consents to receive" , "Says yes" , "Takes; approves" , "Takes (an offer)" , "Believes" .)
