Unusual way to play a squash shot? (3-3-4)
I believe the answer is:
off-the-wall
I believe this is a double definition.
'unusual' is the first definition.
'way to play a squash shot?' is the second definition.
(Other definitions for off-the-wall that I've seen before include "Original" , "like a newly escaped convict?" , "Conspicuously or grossly unconventional" .)
