Judges playing conkers? (7)
I believe the answer is:
reckons
'judges' is the definition.
(reckoning is a kind of judging)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for reckons that I've seen before include "Counts or guesses" , "Judges" , "Conkers (anag.)" , "Estimates" , "Suspects" .)
