Obstruction indicates it's my point perhaps (6)
I believe the answer is:
stymie
'obstruction' is the definition.
(I know that stymie is a type of obstruction)
'it's my point perhaps' is the wordplay.
'point' becomes 'E' (compass point).
'perhaps' is an anagram indicator.
'its'+'my'+'e'='itsmye'
'itsmye' anagrammed gives 'STYMIE'.
'indicates' is the link.
(Other definitions for stymie that I've seen before include "Hinder, obstruct, thwart" , "Frustrate" , "Tricky situation" , "balk" , "Block or thwart, as on golf course" .)
