Q-d7 is met my Q-e5+ forcing stalemate; other moves by the White queen drop material. 2. R-c5 is met by Q-b6+, R-d5 by Q-b6+ followed by Q-b7+. All other plausible rook moves fail to Q-d8+. 3. K-a8 draws after Q-f3+ followed by a capture or Q-a8+ 4. K-c8 is answered by Q-c3+. If then K-d8, Q-d3+. If K-b8, Q-f6 repeats the position. 5. Finally, there is K-c7. Black responds with Q-g7+. If now K-b8, Q-f6 repeats. If K-c8, Q-c3+ transposes into case 4. If K-d8, Q-f6+ forces K-c[78] after which Q-g7+ or Q-c3+ transposes into cases already treated. So the only try is K-[cd]6,Q-f6+,K-[cd]5 (forced) Q-f5+ followed by continuous checks on f1, b1, a2, or f5 as appropriate if White doesn't wish to drop his rook. Undoubtedly, the unique feature of this position is that apart from symmetry, there are probably no other positions where White to move, not in check, cannot win.
