The "Minefield" is a constraint-based puzzle that trains precise board vision and knight maneuverability. Your mission is to navigate the knight across the board to a target square, strictly avoiding all squares attacked by enemy pawns. This drill forces you to calculate safe paths and visualize "no-go" zones, a critical skill for maneuvering pieces through a crowded middlegame.
