Dear George,
I don't think that 6.Nc7+? is the refutation, because instead of 6...Kf8? black
must play 6...Kd8! threatening both to capture the knight on c7 and to checkmate
on f2. The only move for white is 7.Bg5+ and after 7...Qxg5 8. Nxa8 Qf6! white
is doomed, eg. 9.f3 Qxb2 10.Nd2 Qc1-+ or 9.Qc1 Qxf2 10.Kd1 Be3 11.Nd2 b6-+
Greetings
Alex
