Musical; board game (5)
I believe the answer is:
chess
I believe this is a double definition.
'musical' is the first definition.
(Benny Andersson and Bjrn Ulvaeus musical)
'board game' is the second definition.
(I know that chess is a type of board game)
(Other definitions for chess that I've seen before include "This is played on board" , "activity aimed at downfall of a king" , "Benny Andersson and Bjorn Ulvaeus musical" , "Ancient war game whose name may have derived for the Persian for 'king'" , "Pure-skill board game" .)
