    P.S. In the (a) variation, if, after 1.Qxh6 Rxb2 2.Rxg6+, Black plays 2. …Ng7, then 3.Re8+ Qxe8 4.Qxg7#.

    1. Qxh6

    1…Ndf6 2. Bxf6 Nxf6 [2…Ng7 3. Re8+ Qxe8 (3…Nxe8 4. Qh8#) 4. Qxg7#] 3. Rxg6+ Qxg6 4. Qxg6+ Kf8 [4…Kh8 5. Qxf6+ Kh7 6. Re7+ Kg8 7. Qg7#] 5. Qxf6+ Kg8 6. Re8+ Kh7 7. Rh8#

    1…Ned6 2. Bxf6 transposes into the line above.

    1…Rxb2 2. Rxg6+ Qg7 [2…Ng7 3. Re8+ Qxe8 4. Qxg7#] 3. Rxe8+ Kf7 4. Rxg7+ Kxe8 5. Qh8#
