Hello Puzzlers, Let's start with some analysis. The black queen is pinned along the d5-f7 diagonal to the black king. Doctor Z is ready to operate. My solution: 1. Rd1 (creating a double pin) if 1. -Qxc4 (Queen takes queen.) 2. Rxd8+ (Rook takes rook.) Kg7 3. bxc4 (Pawn takes queen.) if 1. -Qf7 (Queen retreats.) 2. Rxd8+ (Rook takes rook.) Kg7 3. Qxf7+ (Queen takes queen.) Black loses a rook in the exchange. Edward In a message dated 4/4/2013 3:04:31 P.M.
