Led after stage of game, being very controlled (5,6)
I believe the answer is:
level headed
'game being very controlled' is the definition.
I can't tell whether this definition defines the answer.
'led after stage' is the wordplay.
'led' becomes 'headed' ('head' can be a synonym of 'lead').
'after' says to put letters next to each other.
'stage' becomes 'level' (synonyms).
'headed' put after 'level' is 'LEVEL-HEADED'.
'of' acts as a link.
Can you help me to learn more?
(Another definition for level headed that I've seen is " Composed".)
