White to play & win...
This game from 1891 has been used as an advanced-beginner level puzzle for many years now. The two players started out with Philidor’s defence followed by the setting up of powers for attack.
1.e4 e5 2.Nf3 d6 3.Bc4 f5 4.d4 Nf6 5.Nc3 exd4 6.Qxd4 Bd7 7.Ng5 Nc6 (Position shown below)
The final Nc6, if not any of the earlier moves (Hello Bd7!), is a highly debatable move.
From this position, White announced a mate in 5 moves. Find out how! The power of a well feared combo comes to the fore in the solution. Can you see it?
The solution will be added as a comment later.
