Left after last chess games (5)
I believe the answer is:
sport
'games' is the definition.
(I've seen this before)
'left after last chess' is the wordplay.
'left' becomes 'port' (left side of a ship - opposite of starboard).
'after' is a charade indicator (letters next to each other).
'last' says to take the final letters.
The last letter of 'chess' is 's'.
'port' put after 's' is 'SPORT'.
(Other definitions for sport that I've seen before include "Eg, rugby" , "Recreation, play" , "Exhibit publicly; eg soccer" , "Eg, football; fun" , "Physical recreation" .)
