White to play and win

Solution

A good challenge. I found it quite hard- a lot of inviting moves, but a quandary about which to play and in which order.

Eventually I cracked it, realising I didn't need to go too far into the line, and once I saw the concept of c2-c4, I knew I was there.

So, 1 fe! Bb5 2 Nf6+! Kd8 3 c4! and it is game over.

Checking afterwards, Houdini tells me 1 Nf5 also wins, but slightly messier; and 2 c4 is equivalent.

I had never heard of Heinrich Wolf before: his Wikipedia entry shows he is a virtual near contemporary of Marshall's, against whom he had a positive score.
