Black: Ra8, Nb8, f7, Rg7, Be6, Bh6, d5, Nf5, g5, e4, h4, Ke3, h3, c2
White: Bb6, Bc6, h5, Nb4, d4, Kg4, Qb2, Rh2

Set:
1. - c1~? 2. Txh3+! Sg3++.
Thematic try:
1. Dxc2? (2. Txh3+) Ld7!/Lc8! > interfering-defence (3. L[x]d7...)
Temptation:
1. Sa6? (2. Dc1+ Kd3 3. Dxc2+ Ke3 4. Txh3+) Ld7!/Lc8! 2. ??

1. La4! (2. Sxc2+ Kd3 3. Da3+! Kc4 4. Se3+ Sxe3++)
1. - Txa4 (3. - Txa3!)
2. Dxc2! (3. Txh3+ Sg3++) Lc8! > interfering defence (4. Dxc8...)
AND:
3. Dxe4+!! dxe4
4. d5+! Sd4++ Mate! >> 5. d5xe6??
The defence 2. - Bc8, played in order to interfere with White, lead to the pronounced contrary - of it's purpose!!
Additional:
3. - Kxe4
4. Te2+! Se3++.

The attempt 1. Th1? thr. (2. Db3+/Dc3+ K~ 3. Dxc2+ Ke3
4. Txh3+) is being refuted in more ways.
