Popular fairy problems 6

Our 9th TT is dedicated to "popular fairy problems". The theme is very vaguely defined and thus the problems clearly "popular" for one composer may be very different from the compositions with that adjective in the view of some other problemist. That's why there is very wide scope for ideas.

This is already 6th file with new examples and again here are some helpmates. All of them show very popular chess move - promotion. It is very rare in over-the-board played chess and thus it is very appealing element, usually. They aren't so much rare in chess problems and there are hundreds of compositions featuring them. 5 given helpmates are only more-or-less randomly chosen examples...

Would you believe it is the position where Black has no waiting move allowing set mating continuation? But it is true. To be fair, some of the black units can be removed without affecting the solution, so it seems the author wanted to show changed set mate with maximum black pieces on the board that can move. Regarding promotions, there is 5 grasshopper promotions in 7 moves, not bad, although f8G and e1G repeat. In any case interesting helpmate despite horrible economy, that can surely be improved.

1.d1S c8Q 2.Sb2 Qe8#
1.d1Q c8B 2.Qg4 Bd7#

Mixed Babson task! Promotions are popular and so finely matched promotions are especially attractive.

a) 1...f8R 2.Kf7 e8S 3.Kg8 Sg7 4.Kh8 Rg8#

b) 1...f8B 2.Kc4 Bg7 3.Kb3 Bc3 4.Kc2 e8Q#

Absolutely economical allumwandlung. There are only two kings and two thematical pawns on the board. Note precisement of bK journeys by avoiding entering the square that must be blocked by white in the mate.

1.f2+ Kf1 2.e2+ Kg2 3.f1B+ Kf3 4.Re3+ Kf4 5.Rf3+ Ke5 6.e1Q+ Kd6 7.Qg3+ Kd7 8.Bh3+ Kc6 9.Qg6+ Kd5 10.Rf5+ Ke4 11.Rh5+ Kf4 12.Qg3+ hxg3#

Usual Ultraschachzwang problem - precisely determined promotions, ideal mate and long journey of white king including irregular round trip.

h#12 (2+4)
