According to Chest this is a mate in 7 and has 2 key moves: Nxa8 and Nbxd7: Nxa8 Ne3+ Kc1 N7d5 Ndb7+ Bxb7 Nxb7+ Ke7 Nhxg8+ Rxg8 Nxg8+ Ke6 Nec5# Nbxd7 Nb5 Nxf8 Nc3+ Kc1 Bd7 Nhf7+ Qxf7 Nexf7+ Nxf7 Nxf7+ Kc8 Ncb6# Although there are 7 different checking moves, the key moves are to capture a queen, and allow black to check white.
