Chooses well-designed spot (4)
I believe the answer is:
opts
'chooses well' is the definition.
'opts' can be an answer for 'chooses' (I've seen this before). I'm not sure about the 'well' bit.
'designed spot' is the wordplay.
'designed' indicates an anagram (designed with the letters).
'spot' is an anagram of 'OPTS'.
Can you help me to learn more?
(Other definitions for opts that I've seen before include "Selects as an alternative" , "Makes a choice from a range" , "Chooses from a range of possibilities" , "Makes choice from post" , "Settles" .)
