Perhaps less than a match? (4)
I believe the answer is:
game
'a match?' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for game that I've seen before include "computer pastime?" , "Willing; recreation" , "hangman say?" , "have a flutter" , "Willing; plucky" .)
