Bishop always gets pint (4)
I believe the answer is:
beer
'pint' is the definition.
(I've seen this before)
'bishop always' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'always' becomes 'eer' (poetic way of saying ever).
'b'+'eer'='BEER'
'gets' acts as a link.
(Other definitions for beer that I've seen before include "It may be 13 across-ed!" , "Ale, lager etc" , "Fermented alcoholic beverage" , "See 4 down" , "Fermented alcoholic drink" .)
