Discontented player receives zero points for difficult question (5)
I believe the answer is:
poser
'difficult question' is the definition.
(I've seen this before)
'discontented player receives zero points' is the wordplay.
'discontented' means to remove the middle letters (the word's contents are removed).
'receives' is an insertion indicator (inserted letters are received).
'zero' becomes 'O' (O resembles 0).
'points' becomes 'se' (two compass points).
'player' with its centre removed is 'pr'.
'o'+'se'='ose'
'pr' placed around 'ose' is 'POSER'.
'for' acts as a link.
(Other definitions for poser that I've seen before include "Question; one trying to impress" , "Conundrum - model?" , "This person's affected" , "Toughie" , "Pseud" .)
