Seem a master as you show foresight (4,5)
I believe the answer is:
look ahead
'you show foresight' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'seem a master' is the wordplay.
'seem' becomes 'look' (synonyms).
'a master' becomes 'ahead' (I can't justify this - if you can you should believe this answer much more).
'look'+'ahead'='LOOK AHEAD'
'as' is the link.
Can you help me to learn more?
(Another definition for look ahead that I've seen is " Eyes front".)
