Where to place armour for first part of fight? (5,3)
I believe the answer is:
round one
I believe this is a double definition.
'where to place armour' is the first definition.
(armour goes around yourself)
'first part of fight?' is the second definition.
(first round of a boxing match)
'for' acts as a link.
(Other definitions for round one that I've seen before include "Start of fight" , "Where armour should be" , "start of contest" .)
