Fairy helpmates with echo diagonal-orthogonal 6

Do you remember our older tourneys - 1st TT CCM for helpmates with twin formed by moving black king and 10th TT CCM for problems with twin formed by exchange of places of static pieces? In this file you can find the helpmates that would suit these thematical requirements, but they are intended as examples for 14th TT CCM - and this is already the 6th special example file.

a) 1.Sb2 e8B+ 2.Rxe8(Bf1) Bxb5(b7)#

b) 1.Rd3 e8R+ 2.Bxe8(Rh1) Rxh7(Sg8)#

Good analogy in the position where White has only 2 units - king and pawn. Lines from the Circe square are opened twice and mating move is capturing, blocking the flight - and this everything is in a very consequent D-O analogy.

a) 1.Gb4 Gg4 2.Rd5 Gd4#

b) 1.Gf2 Gb6 2.Bd5 Gd4#

Final antibattery mates are formed in echo diagonal-orthogonal, with preceding blocking and Grimshaw.

1710 Phénix 24 - 1993

a) 1.LEgb3 Bg7 2.Rd6 Sd3#

b) 1.LEg6 Rc5 2.Sd6 Sf3#

Not too fairy example... almost whole play is orthodox and the mates are given by a normal doublecheck.

3rd Prize Acheres 1993

a) 1.Rxb7 f8B(Sb8) 2.Rxb8 Bh6(Sd6)#

b) 1.Bxb7 f8R(Qb8) 2.Bxb8 Rf3(Qb3)#

That's quite unusual example of echo diagonal-orthogonal. The "active" promotions at f8 are into B and R, "passive" ones at b8 into remaining S and Q. The correspondence between B and R elements is strong, despite the difference in mating moves.

a) 1.Rxd2(w) Rd5 2.Sd4 Re5#

b) 1.Bxd2(w) Bf4 2.Se3 Be5#

Andernach chess was brought to the majority of composers by the WCCT and subsequently many interesting, even if not super, helpmates appeared. 6 line pieces on 3 first rown play accordingly in two phases. Temporary unpin of black knights isn't especially appealing to me, however...

7th Prize Andernach 1996

a) 1.Bc2(w) Rb4(b) 2.Rxc2 Bxb4#

b) 1.Rc2(w) Bb4(b) 2.Bxc2 Rxb4#

On the other hand, Antiandernach chess still seems too constrained in the offered possibilities of the strategy shown. In this problem complete play in the style SSST (same square - same time, for more examples see of SSST thematical index of CCM - S) is shown, with natural differentiation of B and R moves - check x no-check mechanism.
