Plays for time in certain theatre seats (6)
I believe the answer is:
stalls
This might be a double definition.
'plays for time' is the first definition.
(to play for time is to stall or delay)
'theatre seats' is the second definition.
(I've seen this before)
'in certain' acts as a link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for stalls that I've seen before include "Evasive moves" , "Booths" , "Posh seats in the theatre" , "Compartments in stables or theatres" , "Deliberately delays" .)
