I am still working on your position. 9.Kc8 is very difficult. I hope I read the moves correctly. Very good test position.


1. Bxc5+ Kxc5 2. d4+ Kxd4 3. Nb5+ Kxe5 4. Nd3+ Kxf5 5. Nd4+ Kg6 6. Nf4+ Kg7 7.Nf5+ Kf8 8. Ng6+ Ke8 9. Kc8 gxf3
Position after this line.

You've said it.
Stockfish 1.7 even finds the best move rather soon with Zugzwang detection on and maximum Aggressiveness (200 instead of 100), but then gets stuck with 9.a6 instead of Kc8.

Hello,

This is a mate in 13. One could have tested it for at least 3 sec with Chest. It falls in the same category with not seriously made ChessBase reviews.

Now I understand why everything is "brilliant"

What is "this"?

Are you referring to the original position?
[D]6br/1KNp1n1r/2p2p2/P1ppRP2/1kP3pP/3PBB2/PN1P4/8 w - -

Or to this related position (which seems to be Mate-in-13) from kgburcham's post?

Amazing! I don't think any engine gets mate in 22.
9. Kc8 is tough to see from the first position.
