Put in position at home to play for time (7)
I believe the answer is:
install
'put in position' is the definition.
(I've seen this before)
'home to play for time' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'to play for time' becomes 'stall' (I've seen this before).
'in'+'stall'='INSTALL'
'at' is the link.
(Other definitions for install that I've seen before include "Set up, ready for use" , "Set in place" , "Station" , "Put in - invest" , "Emplace" .)
