C10
1. Rg1-g2 Ph3xg2
2. Rh1-g1 Pg2xf1Q
3. Rg1xQf1
Black should concede now, coz only the King can move, and white is able to bring rook and king through h-row in blacks area and thatīs it....

The problem with that is... black will NOT eat the rook.

Yeah...tricky one this is. Well, as all others. 
Queen on a2 leads to checkmate though, so that's not either.

In both cases, everything on the board in there for a reason.

I don't doubt that, nor do I doubt there's perfectly nice solution, just don't see it.

Queen on a2, pawn eats it. Now just a matter of getting queen to c3, then d2 with mate. Can't move king as immidiate checkmate follows.
Moving pawn on b3 doesn't improve anything much.
Could work moving king away first, maybe getting rook to where king was.

But u donīt need to move the King. You can move your rook on the other side...so the pawn can change into queen, but never make mate....

Yeah, I know. Last line in my previous post.
Didn't play with it yet.
EDIT:
This could be possible position then...
Still don't see any big advantage for white.

Obviously, you have to move BOTH rooks to the "front lines" before you start.
I've been experimenting with all of those, but I didn't find a winning combination yet. So far all of those end up with white getting checkmated, perpetual check, or black closing the pawns down with his king. I'll have to think more about this one.
Here are the 3 combinations that I consider:
Rc2, Kc1, Re1.
Rc2, Rc1, Kd1.
Rc1, Rd2, Ke1.

What about the cylinder chess problem? It's very nice and not so hard to solve it (knowing that there must be a unique solution and that there are practically two ways only for the king to get mated on the last line).
edit: I think I mistyped it. Of course it's a 4-mover (mate in 4 moves)

A meta-hint perhaps for the cilinder problem: the starting position is completely symmetric. So, if there is to be only one solution (which is the case), the key move has to preserve the symmetry.

Why not four?

Because I can't think of the 4-th combination that's anywhere near useful. Anyways, here it goes:
move 1 - till about move 20 :
Reposition the rooks and the king (black loses if it eats one of the rooks):
Rc2, Rc1, Kd1. The black king will most likely be on b6 or b5.
20. Qa2 bxa2
21. b3 a1Q (b4+ is the reason the black king can't stay on a5 or c5)
22. bxc4+ Kxc4 (or Kc5 if the black king is on b6 - in that case move 24 will be d4+)
23. Ke1 dxc2 (if black does not eat the pawn, white will move c3 and win with an overwhelming advantage)
24. d3+ exd3 (black can also eat with the king, i guess, but that won't really change much)
25. Nd2 cxb1Q
26. Nxb1 (now white has a lot of pawns, most of which are well-defended and clustered together, a knight and a rook against a queen on its own - that's a win)

Hmm, white has rook on c2, not pawn which is already on c3...
EDIT: This seems to be position on your 22nd move, unless I missed something (quite easily  ).

Yes, Einstein. The rook is indeed on c2 and the pawn is indeed on c3. Very good observation. Is there a point to your post, or you are just stating the obvious?
Edit: yes, this is exactly how the board looks before move 23.

What happens after 23...Kb3, I wonder?
Or after 21...axb3, for that matter?
