If it is right they are: 1 Kc3 Rd3 Kc1 Nf1 2 Kc3 Rd4 Ke3 Nb2 3 Kc3 Rd4 Ke5 Nb2 4 Kd3 Re2 Kd1 Ng4 5 Kd3 Rc3 Kd1 Na1 6 Kd3 Re3 Kd1 Ng1 7 Kd3 Rc4 Kb3 Ne2 8 Kd3 Re4 Kf3 Nc2 9 Kd3 Rc4 Kb5 Ne2 10 Kd3 Rc4 Kd5 Na2 11 Kd3 Re4 Kd5 Ng2 12 Kd3 Re4 Kf5 Nc2 13 Kd4 Rc3 Kd2 Na5 14 Kd4 Re3 Kd2 Ng5 15 Kd4 Re3 Kf2 Nc5 16 Kd4 Re3 Kf4 Nc1 17 Kd4 Re5 Kf4 Nc7 18 Kd4 Re5 Kf6 Nc3 Guido
