Pay close attention mostly to one stirring game (4,5)
I believe the answer is:
stud poker
'game' is the definition.
(stud poker is a kind of game)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for stud poker that I've seen before include "Card gambling game -- Turk's dope (anag)" , "Gambling game with some cards turned face up" , "Variation of five-card gambling game" , "It involves dealer" .)
