Not so fast, but much shorter: :-)

1... Qe2+ 2.Kg3 Bxg2 3.Qxg2 Nh5+ 4.Kh3 Nxf4+ 5.Kg3 Qxg2+ 6.Kxf4 Rfe8 7.Re1 Rxe1
8.Ba3 g5+ 9.Kf5 Re5#
1... Qe2+ 2.Kg3 Bxg2 Qe1 Ne4+ 4.Kh4 Ne5 5.Qg3 g6 6.Qg5 Nxg5 7.Kg3 Ne4+ 8.Nxe4
Qf3+ 9.Kh4 Qg4#

(See my other message to know, how I found these solutions with ChestUCI)

Best regards,
Franz.
