Problem 788: Aleksey Oganesjan - Helpmate
aleksey.oganesyan(27.12.2016) A pair of delightful Bristols in miniature by the Russian expert!


788. Aleksey Oganesjan (Russia)
(after R. Wiehagen)
H#2        2 Sol.        (4+2)
1.Kb3! Rb1+ 2.Kc2! Qc1#
1.Kb4! Ba6 2.Kc5! Qb5#
6-piece-problem with White Bristol, function permutation of wR/wB and
Paradoxical nuance: Black King’s walking from the edge of a board to its center.   
After P0575908. Also compare to P1005155

Pr.788 is quite nice with the BK's move to the centre!
But in P0575908, Black's clearance manouvre in both phases is harmonious and pleasing!

P0575908 is a diluted H#1.5:
-Pb3 -Bg3 ->h#1.5

P0575908 is a diluted H#1.5

I think it is disputable.
In P0575908, the first black's move produces a curious delayed Umnov effect

P0575908: at first the B1 produce the captures of black unites, unpleasant especially when it comes to Bristol maneuvers.
The Umnov seems genuine: the bP and the bB could stay only on b3 and g3 (or in the box).
