Kings and queens on the board? (5,6)
I believe the answer is:
chess pieces
'kings and queens on the board?' is the definition.
I can't judge whether this definition defines the answer.
'kings and queens on the board?' is the wordplay.
'kings and queens' becomes 'pieces' (I am not sure about this - if you are sure you should believe this answer much more).
'on' is a charade indicator (letters next to each other).
'the board?' becomes 'chess' (chess board is a kind of board).
'pieces' after 'chess' is 'CHESS PIECES'.
Can you help me to learn more?
(Another definition for chess pieces that I've seen is " bishops?".)
