CJF: "It was interesting to read about your new TT. Five h# phases is not so uncommon. There are well over 200 examples in my h#2 collection. I believe the earliest example (h#2, but probably also the earliest h#n with 5 phases) is Pauly's no.1564 in 'The Chess Amateur' January 1930 (PDB P0513828). However this problem does not have 5 genuine phases, but only one solution and a 4x-branching set play."

CJF: "From the same year and by the same composer however, there is no.277 in 'Magyar Sakkvilag' (October 1930; P0550530) which is of the form 3.1.1.1 + 1.2.1.1. I have Pauly's own diagram of this before me as I write (he sent it to Dawson for his records), and it is inscribed, in a mixture of English and French: 'Helpmate in 2 Type Neumann 5 échos'."

a) 1.Kd3 Qf1+ 2.Ke4 Sf6#

b) 1.Kd5 Sf4+ 2.Kd6 Bc5#

c) 1.Kf3 Bb3 2.e4 Bd1#

d) 1.Kd5 Kb5 2.e4 Sf4#

e) 1.Kf5 Sf4 2.Kf6 f8Q#

Compare this problem to h#2 by Henry Forsberg with the almost the same twin mechanism - here the twins are made by changing white unit instead of black one. Pity that some black moves are repeated, 1.Kd5 and 2.e4...

1.Sxc2 Ba4 2.Kc4 Bb3#

1.Sxb5 Rd2+ 2.Kc6 Sd8#

1.Sxe6 Rc3 2.Kd4 Rd3#

1.Sxf5 Rd2+ 2.Kxe6 Bc4#

1.Sxf3 Rc3 2.Ke4 Bc6#

All the first black moves are made by Sd4, all second by bK. Furthermore, note that in the first triplet of solutions there is a cyclical Zilahi there!

The same combination of solutions as in h#2 by Wolfgang Pauly.

a) 1.Kd3 d7 2.Kc2 d8Q 3.Kxb1 Qd1#

b) 1.Kd5 b6 2.Kc6 d7 3.Kb7 d8S#

c) 1.Kxf3 g7 2.Kg4 g8B 3.f3 Be6#

d) 1.Kf5 g7 2.Kg6 g8R+ 3.Kh7 Rg7#

e) 1.Kxf3 d7 2.Kg2 dxc8Q 3.Kh1 Qh3#

Position a), b), d), e) form big star of bK and there are 5 different promotions. Compare to h#3 by Fadil Abdurahmanovic. Here in the solution not fitting to big star bK moves - but he is mated on the different square. Also there 4 different promotions making full AUW.
