You must have done something wrong with Chest, as Nc4 is a mate in 6, according
to CM9000. Actually, there are SIX moves that lead to mate in 6 -- Nf3, Rh3,
Rg3, Nc2, Nf7 and Nc4.

Additionally, CM9000 says that Ng6 is a mate in 11 (or possibly better):

1.Ng6+ Ke4 2.Re5+ Kd4 3.Nc2+ Kc4 4.Rb4+ Kd3 5.Nd4 Nc3 6.Nf4+ Kd2 7.Nf3+ Kc1
8.Rc5 Kb1 9.Rxc3 Ka2 10.Nd2 Nd7	11.Ra3#
