'strategy' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'concerning encounter' is the wordplay.
'concerning' becomes 'moon' (I am not sure about this - if you are sure you should believe this answer much more).
'encounter' becomes 'face' (facing is a kind of encountering).
'moon'+'face'='MOONFACE'
