the Rose e2, due to the isardam}Kd3-e4 + {similarly, wK does not check
bK because the Rose e2 paralyses it with isardam : e2-f4-e6-c7-a6} 3.WNe1-c5 !! {pinning
the bK; the Rose a6 must continue to "pin" the wK, but c7 and e6 are
unavailable, so Black has only one move : } BNg3*e2[+wROf8] #{NIc5 is
pinned because of the isardam f8-e6-c5-a6, so it does not check the bK; and
wK cannot play because of the isardam f8-g6-f4-d3-b4-a6, which is why it was
the White Rose on f8, intersection of the two paths of the a6 Rose
two paths of the a6 Rose, via c5 and via f4; the double threat ...Kxf4 & ...
NIxf4 is unstoppable}
1.ROf3-g1 + f2*g1=BR[+wROe4] 2.Kf4*g3[+bBNa2] + Kd3*e4 [+wROc6] {bK is not checked by the NIg5 thanks to the isardam effect of NIa2; it is also pinned} 3.Kg3-f3 + !! {wK does not check, as the g1 Rose cannot come to f3
to f3 because of the Rose c6} BNa2*c6[+wROb3] #
{NIg5 does not check bK because the Rose g1 paralyses it with the isardam (h3-g5-e6-c5-b3). Neither does the RB
(g1-f3-d4-b3). It was therefore imperative to revive the White Rose in b3, intersection of the two paths of the g1-Rose, via g5 and via f3. The threat ...Kxf3 is unstoppable. Surprising problem: even if we limit ourselves to the final 1# reverse (in each solution), it is already remarkable. The very last move is indeed the only legal one, as the Rose cannot be placed elsewhere.
And it's mate to the White King.}
