    The dance of the knight:
    1.Ne6 threatens Ng7 # or if 1. ... Be5 2.Ng7+ Bxg7+ 3.g4#
    1. ... Bf2+ only way to avoid the mate
    2. Nc5 threatens g4# or if 2. ... Bxc5 3.Kb7 and 4.g4#
    2. ... Bg3 only way to block the g-pawn
    3.Nd7 threatens Nf6# or if 3. ... Be5 then 4.Nxe5 and 5.g4#
    3. ... Bf2+ only other move
    4.Nb6 threatens g4# or 4. ... Bxb6+ 5.Kxb6 and 6.g4#
    4. ... Bg3 only other move
    5.c4! threatens Nd5 and Nf6#
    5. ... Bxc4 only way to avoid Nd5 path
    6.Nd7 this move on the 5th move would have failed because of a later Rxc3 and at least another check on the white king (found this only after I tried that as the solution), now the bishop blocks this path
    6. ... Bf2+ only option
    7.Nc5 threatens g4#
    7. ... Bg3 only option
    8.Ne6 threatens again Ng7# or Be5 Ng7+ Bxg7 g4#
    8. ... Bf2+ only option
    9.Nd4 Bg3 (as above)
    10.Kb8! here the absence of the Rxc3 and Rxc8+ becomes apparent. Now black has no defense against 11.Ne6, 12.Nf4+ and 13.g4#

    David and Mephisto are correct. The problem was composed by M. Vukcevich.

    on move 12, wouldn't you just do Ng7 ++, because he can take the knight with the bishop on move 12
