Crazy position from Scherbakov's new book on the triangle

Black to play and draw. I had my engine running for at least a few minutes and it was unable to solve it. The engine should find the whole line, not just a few moves of course.

Clearly, GM Scherbakov has put in a lot of time and effort on this book. Worth purchasing if the triangle system interests you from either color.

Is this the drawing line:

1... Nh3+ 2. Kh2 Nh5 3. gxh3 Qg3+ 4. Kh1 axb3 5. Rxa7 Rxa7 6. Rxa7 Bb5

Yes! There are things to work out even after Bb5. Did you use an engine?

Actually I just played around and found it. But usually I use IDeA...it finds anything.

Great job then!

I wonder how engines will fare without Idea.
