forking the rook while checking the king
A shogi tactic where a player simultaneously checks the opponent's king and attacks the rook, forcing the opponent to lose the rook.
I executed a king-check rook-fork and captured the opponent's rook for free.
王手 means 'check' (threat to the king), while 王手飛車 is a specific tactic combining check with an attack on the rook.
飛車 is the rook piece; 王手飛車 is a compound term for the tactic involving both the king and the rook.
Compound of 王手 (check) + 飛車 (rook), literally 'king-check rook-fork'. The term is specific to shogi and describes a double threat.
