Hello all, Doctor Z has his scalpel ready. My solution: 1. N g5+ (Knight checks king and frees the rook on the e-file threatening the black knight. White is taking control of the e and d files with rooks.) The black king could move to escape check. 1. -K e7 2. Qx e6 (Queen takes knight.) Kf8 3. Qf7++ (Queen checkmates with protection from knight.) 1. -Kg7 2. Nx e6 (Knight takes knight.) Kf7 3. Nxd8 (Knight takes queen.) R a xd8 (Bishop cannot take knight since pinned.) 4. Rd7+ Rxd7 (Rook takes rook.) 5. Qxd7+ (Queen takes rook.) B e7 (blocks check) 6. Qx e7+ (Queen takes bishop.) Kg8 7. B e5 (Bishop controls the long diagonal.) Rh7 8. Q e8++ (King cannot reach g7 because of bishop.) 1. -K e8 or -Kg8 2. Qx e6+ (Queen checks king.) 1. -Kf8 2. Nx e6+ (Knight takes knight.) Black knight can take the white knight on the first move. 1. -Nxg5 (Knight takes knight.) 2. Rd7+ (Rook checks king.) Qxd7 (Queen takes rook.) 3. Qxd7 (Queen takes queen.) or 2. -Kg8 3. Qxg6+ (Queen takes pawn.) Kf8 3. Qg7++ or 2. -Kf8 3. Bxg5 (Bishop takes knight.) Rh7 4. Rxd8+ (Rook takes queen.) Rxd8 (Rook takes rook.) 5. Qxf6+ (Queen takes bishop.) Kg8 6. Qxd8+ (Queen takes rook.) Kg7 / Kf7 7. R e7++ (Bishop covers escape squares.)
