a simple h#


Here is a simple miniature I composed recently. Probably anticipated! Easy to solve!
(= 3+4 )

h#2 Two solutions

Possible version:
(= 3+4 )

h#2 4 sol.

A pity it couldn't be a AUW...

Like (say) in something like this:

(= 4+5 )

h#2, 7 solutions

Hm... Two of the solutions are practically the same, and repeats the Q promotion. Then:

(= 4+7 )

h#2, 5 solutions

This is also an excellent development showing AUW and more! It can be economised of course.

(= 4+5 )

h#2 5 solutions

1.g2-g1=B a7-a8=Q 2.Bg1-b6 Qa8-c8 #
1.Bh5-g4 Rg8-b8 2.Bg4-c8 b7*c8=Q #
1.Sa6-c5 b7-b8=S 2.Sc5-b7 a7-a8=S #
1.Sa6-c5 b7-b8=R 2.Sc5-d7 Rg8-c8 #
1.Kc7-d7 Kg5-f6 2.Sa6-c7 b7-b8=S #

Yes, that extra solution with two wN promotions have some charm (in spite of the move repetitions...)

An alternative for a single colored AUW:

(= 5+5 )

h#2 4 solutions

The star-Pawn is annihilated in the fourth solution, and this is (I believe) a pleasant compensation for the need of a second acting wP...

Really a nice problem, good construction.

All model mates too! Deserves to be more widely known

Ph7 is needed!

It is sound without h7. But perhaps not all models.

Sorry, I overlooked the change Bd6, a nice improvement.
It's hard to get a model mate with the queen.
