No.123. Interesting repeated echo mates. Seems the basic idea can be shown in 1.5 moves!! WRf2 WRh1 BKb2. Koeko H#1.5 (3 solutions)
1…Rh1-a1+ 2.Kb2-b1 Rf2-c2#
1…Rh1-b1+ 2.Kb2-c1 Rf2-d2#
1…Rh1-c1+ 2.Kb2-b1 Rf2-a2#
The BK move is repeated once, just as in the above version !

Thank you!
You’re right! Please see this variants too:

If a) WRh1 WRh2 BKb2 Koeko H#1.5 (3 solutions)

1…Rh1-a1 + 2.Kb2-b1 Rh2-c2 #
1…Rh1-b1 + 2.Kb2-c1 Rh2-d2 #
1…Rh1-c1 + 2.Kb2-b1 Rh2-a2 #
and
b) BKe2 Koeko H#1.5 (5 solutions)

1…Rh1-d1 + 2.Ke2-e1 Rh2-f2 #
1…Rh1-e1 + 2.Ke2-f1 Rh2-g2 #
1…Rh1-e1 + 2.Ke2-d1 Rh2-c2 #
1…Rh1-f1 + 2.Ke2-e1 Rh2-d2 #
1…Rh1-g1 2.Ke2-f1 Rh2-e2 #

No.124 shows the interesting idea of black king forming two different batteries on the nightrider lines. The rest of the play I wish was equally interesting.

Thank you!
Just a dream: the WK could move onto d1-d3-f1-f3/King-Star.
The mate realizable on f1 from Twin B, for example so:

White Ra4 Rc4 Sd4 Ke2
Black Pa7 Nc7 Pd6 Kd5 Rb4 Ph3 Bf2
hs#4

1.Sd4-b3 Bf2-b6 2.Rc4-c6 Rb4-e4 + 3.Ke2-f1 Re4-e5 4.Rc6*d6 + Kd5*d6 #

but I don’t like this variant because the switcback-mate and the double sacrifices disappeared. This solution is not in a perfect harmony with the other two.
