Bridge champion gets a hiding (8)
I believe the answer is:
spanking
'a hiding' is the definition.
(I've seen this before)
'bridge champion' is the wordplay.
'bridge' becomes 'span' (synonyms).
'champion' becomes 'king' (I've seen this in other clues).
'span'+'king'='SPANKING'
'gets' acts as a link.
(Other definitions for spanking that I've seen before include "Fantastic" , "Physical punishment" , "excellent" , "Lively" , "Outstanding - traditional punishment for children?" .)
