Soylent Green’s analysis is of course correct, but it does not deal with interesting defences by Black. Thus, after 1. Bc7 Ka6 2. g7, Black can play 2… Nd8, intending 3…Be6. White has to play 3. B x d8, and only then Black plays 3…Ba4. After 4. Kc4 (forced), Black then plays 4…Be8, setting a trap: 5. g8=Q Bf7 6. Q x f7 stalemate. However, White can instead play 5. g8=B! and should win.
1.Bc7+ Ka6 2.g7 Ba4 3.Kc4 Bb5+ 4.Kc3 wins

Absolutely right!
2…Nd8 is a very nice move and the puzzle is not so easy as it seems.
Thank you!
nice puzzle
