Like this geodesic representation. 🙂
Unique white moves are forced by the black first move each of which block a flight square so that white…
@WinChloe: After 1…Q×h1(Qd1N;Sd8) 2.Rg1(B;+g7) R×d1(Rh1N;Qé8) Popeye considers it is not mate because of 3.Qg6=wQ ! using condition Isardam. In the…
Sorry, with Anticirce Calvet, it is only three solutions: 1…Q×h1(Qd1N;Sf7) 2.Rg1(B;+g7) R×d1(Rh1N;Qé8)‡ 1…Q×h1(Qd1N;Sd8) 2.Rg1(B;+g7) R×d1(Rh1N;Qé8)‡ 1…B×g7(Bç1N;Rd2;+b2) 2.Q×a2(Qd8B;Rg8)+ K×b2(Ké1;é3)‡ SL
Winchloe gives all these solutions: 1…Q×h1(Qd1N;Sf7) 2.Rg1(B;+g7) R×d1(Rh1N;Qé8)‡ 1…Q×h1(Qd1N;Sd8) 2.Rg1(B;+g7) R×d1(Rh1N;Qé8)‡ 1…B×g7(Bç1N;Rd2;+b2) 2.Q×a2(Qd8B;Rg8)+ K×b2(Ké1;é3)‡ 1…B×g7(Bç1N;Rd2;+b2) 2.Q×a2(Qd8B;Rg8)+ K×b2(Ké1;ç2)‡ 1…B×g7(Bç1N;Rd2;+b2) 2.Q×a2(Qd8B;Rg8)+ K×b2(Ké1;a8)‡…
I'm pretty sure that I've seen such mates somewhere, perhaps it was hs#4 with w&b promotions into Rooks.

I like very much the part (a) with the "follow-me" pattern! Though the play and mates are different, not sure…

846. One cannot be faulted for arguing that 'a2-c4-c2' is longer than 'a4-c4-c2' :). Obviously the starting-landing sqaure (not the…
