A beautiful, rich yet accessible study, with multiple appeareances of De Villeneuve Esclapon's drawing motif. Highly recommendable!

It took me some time to solve it, initially having walked in virtually all traps.

The first principal choice is between 1. Ne3+ and 1. Nf4+. Of course, 1. Rg1 and 1. Rh2 both fail to 1. ..., Nf3+.

1. Ne3+

The refutation of 1. Nf4+ is not at all obvious: 1. Ke4 and now:
a) 2. Nf2+, Kxf4 3. Rxh4+, Kg3 4. Rg4+, Kh2 5. Rh4+, Kg3 6. Rh3+, Kf4 7. Nf4+, Kg4 8. Nf2+, Kf4 draw
b) 2. Nxg2, Nxg2+ 3. Kf2, Ne3! The saving resource 4. Nxe3, Bd4
b1) 5. Re1, Bc5 De first V-E: perpetual pin!
b1) 5. Rh3, Kd3! prevents 6. Ke2. The second V-E! draw!

1. ... Ke4
2. Nxg2, Nxg2+
3. Kf2, Nf4
4. Re1+!

After 4. Rxa1. Nxh3+ 5. Kg3, Ng5 the black knight is safe.
After 4. Nxf4, Bd4+ 5. Kg3, Be5 and again after either 6. Rh4 or 6. Rf1 we see De V-E's perpetual pin. In the latter case, Black must not forego 6. ..., Kf5! in order to prevent 7. Kg4.

4. ..., Kf5
5. Nxf4, Bc3

Here, after 5. ..., Bd4+ 6. Kf3 there is no pin and Black loses prosaically.

6. Rc1, Bd2

Seemingly rescuing Black. But:

7. Rc5+, Kxf4
8. Ke2

trapping the bishop! After both 8. ..., Bb4 and 8. ..., Be3 the piece drops off after 9. Rc4+.
