Thank you Vaclav! I received this problem with looks like Popeye solution and didn't check it myself. I will contact the author.

With black pawn h7 (for instance), if composer can force switchback also, the problem will be great. Just a suggestion, I cant see how the final move Pg5xh6 can be forced.

The new version (published above) is with nice double Gate opening by bRf6 and switchback by bBh6. Hope it's correct (the problem is partially check with "Alibadix" inteligent mode by Vaclav Kotesovec).

On partial checking I found an interesting cook starting 12. g:h2 13. h1R ... etc. So the white rook h2 has to be at h5. This eliminated the cook starting from 12th move. But still the problem is not C+, as full test is still difficult.

Its not problem the bR to be moved to h5, h4 or h3... There is enough time till to the end of the year the correct version to be find.
But how the black can be stalemated after 13.h1R? Can you give us other moves too?

The cook
12. g:h2 13. h1R 14.h6 15.h:g5 17.g3 19.Rg4 20.Bh4 21.g5! any ! The moves are interchangeable of course.

Yes, you are right... The problem can be solved even in 15 moves. For example 1.gxf2 2.f1R 3.Rh1 4.Rxh2 5.Bg7 6.h6 7.hxg5 8.g4 9.g3 10.Rh4 11.Rg4 12.Bh6 13.Bg5 14.Bh4 15.g5 ~ =
So the version with movement of wR on h5,h4... etc. on the initial possition is useless...
In the partial computer check the problem was C+, but with the strict addition bPg3 to not move...

It does not solve in 15 moves, as white pawn f2 has to be removed for black to be stalemated (h6 pawn finally reaches g3). Black bishop cannot come through g5 shortcut to f2, because without WPg5 BPh6 cannot reach g3. So the cook is 22 moves long. Moving the white rook h2 to h3/h4 will produce other cooks. So it should be at h5 (allowing the black g6 pawn a capture to avoid cooks).

The 15 moves cook solution in the version 139.1 is fine Ram. The wPf2 is captured on the first move, bB come to h4 after Bg7-Ph6xg5...Pg4-Bh6-g5-h4. Check again the solution above.
Ofcourse some moves can be in not the same order, but you got the point.

Sorry. You are right Diyan. I was still thinking on the lines of 1.g:h2 :( . Hope Mr.Anton can think of some way out.
