Others with skill go back to square one (7)
I believe the answer is:
restart
'go back to square one' is the definition.
(I've seen this in another clue)
'others with skill' is the wordplay.
'others' becomes 'rest' (eg the rest of a group).
'with' says to put letters next to each other.
'skill' becomes 'art' (both can mean a talent).
'rest'+'art'='RESTART'
(Other definitions for restart that I've seen before include "Resume" , "begin afresh" , "Jumping the gun will mean" , "Commence again" , "Begin anew" .)
