Make wrong move with queen taking rook? (3)
I believe the answer is:
err
'make wrong move' is the definition.
(to err is to make a mistake or blunder)
'queen taking rook?' is the wordplay.
'queen' becomes 'ER' (short for Elizabeth Regina ie Queen Elizabeth).
'taking' is a charade indicator (letters next to each other).
'rook?' becomes 'R' (chess abbreviation).
'er'+'r'='ERR'
'with' acts as a link.
(Other definitions for err that I've seen before include "Miscalculate" , "Miss the mark" , "Bungle" , "Sin" , "Make a wrong move" .)
