  • Activity
  • Coordination

Mysterious rook move is a piece-play concept: coined by Nimzowitsch to refer to the placing of a rook on a closed file in anticipation that the opponent is going to open the file. This move may either achieve a position with a rook on an open file, or it may alternatively hinder the opponent's intentions (prophylaxis). Ask whether the piece is active, coordinated, and serving a real plan.
