Bridge feat (4)
I believe the answer is:
slam
'bridge feat' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for slam that I've seen before include "Criticise - bang - very good result at bridge" , "Shut loudly and forcibly" , "ambitious bid" , "Crash (door closed)" , "Severely criticise; shut (a door) forcefully" .)
