Bluster; card game (4)
I believe the answer is:
brag
I believe this clue is a double definition.
'bluster' is the first definition.
(I know that bluster can be written as brag)
'card game' is the second definition.
(brag is an old card game)
(Other definitions for brag that I've seen before include "Card game, like poker" , "Blow one's own trumpet" , "Show off, crow" , "Boast about garb" , "'Show off, boast (4)'" .)
