Long fairy helpmates 1

In this series of pages I'd like to turn attention of readers to relatively little exploited field of fairies. Without any doubts, the most popular genres for fairies are #2 and h#2. In both direct play and helpplay the increasing number of moves rapidly increases the danger of cooks. That's why there is relatively small portion of longer fairy helpmates among all published fairy problems. The development in orthodox helpmate moremovers has come very far in recent years, many records unbelievable, let's say, 10 years before, are reached. Without any doubts, it is thanks to available testing by computers. Could such an explosion uprise in fairies too? That's a question. Let's look to 'what has been done' during waiting 'what great will appear'.

Interesting "fight" of both sides to give white material strong enough for mating.

Spotlight comment by Juraj Lörinc:

Fairy piece moa is a main reason of aiming the spotlight onto this problem. One of recent fairy tourneys have asked for h#2 with mates given by neutral pieces. (The link with the current problem will be clear in a minute, just be patient.) We had similarly oriented the 17th TT CCM in 2005 and generally speaking, I am quite interested in problems with neutral mates. The point is in the irreversibility of the mating move by neutral piece. It is possible to make this possible in many ways: promotion, capture on the pin line, battery opening by grasshopper jumping far enough - or one-way move by mao/moa with the return move blocked. (And here we are!)

So I was just looking at problems with mao and moa, not to compose something similar, just because of pure curiosity. The present problem stood out not because of very specific use of moa properties, rather because of the relative simplicity of showing visually attractive theme: two simultaneous cyclic exchanges of places of three pieces. Yet, there are also quite a few orthodox versions of the present task existing (e.g. h#5 by Torsten Linß and Rolf Wiehagen that entered also Album FIDE).

So there is a question: has such fairy composition the right to existence? Yes - this is my answer. Yours can be different.
