'extremely cunning' is the definition.
(arch can mean mischievous or cunning)

'skill to take in short game' is the wordplay.
'skill' becomes 'art' (both can mean a talent).
'to take in' is an insertion indicator.
'short game' becomes 'ches' (I can't explain this - if you can you should believe this answer much more).
'art' enclosing 'ches' is 'ARCHEST'.

'that's' is the link.
