Look good beside pike (6)
I believe the answer is:
glance
'look' is the definition.
(glancing is a kind of looking)
'good beside pike' is the wordplay.
'good' becomes 'g' (abbreviation).
'beside' is a charade indicator (letters next to each other) (I've seen this in other clues).
'pike' becomes 'lance' (I can't explain this - if you can you should believe this answer much more).
'g'+'lance'='GLANCE'
Can you help me to learn more?
(Other definitions for glance that I've seen before include "it has a metallic lustre" , "Peek" , "Momentary look" , "Look quickly at -- cricket stroke" , "A dart of the eye" .)
