This position (if white is on move) actually loses for white. But if black is on move, it wins.

Yeah, white could get queen then on c column I think.
Ah no worries, Angelito. I could've been called worse, like Hawking, or Newton. Ewww.
Anyway, he saw my point, acknowledged it, then returned to previous stance.

When I was talking about overwhelming advantage, I didn't consider Kb3 I assumed the king would move back. Anyways, here it goes:
23. Ke1 Kb3
24. c4 dxc2
25. d4 cxb1Q
26. Nd2+ Ka2
27. Nxb2 Qb2 (no matter where it moves, really, black will lose the queen either way)
28. Nc3+ Kb3
29. Rb1 Kxc3
30. Rxb2 Kxb2
31. d5 Kxa3
32. d6 Kb2
33. d7 a3 - white makes it first 
Edit: No, Nebs, you had no point You've replaced your ORIGINAL "point" with "never mind" (but I DID read it before you deleted it ). But looking at the board made me realize that I missed the above combination which is what I acknowledged And apparently, you did see it at about the same time judjing by your post below the "never mind" one

Well, judging by the responses from csarmi and Ribannah, unlikely that's the solution...but let's play with it a bit.
I'd counter your
26. Nd2+ with Kxa3 not Ka2.
Maybe even
25. d4 exd3
EDIT: Nevermind now about that Russ!

Well, we can agree that Qa2 must happen if white wants win.
Now, when...that's a toughie at the moment.

Black plays 25...Kb2 or 25...exd3.

After 23...Kb3 White should play 24.Rb2+ to draw.

I think I got it now...
Rc1, Re1, Kf2, the black king is on b6 (as usual):
20. Qa2 bxa2
21. b3 Qa1 (axb3 or cxb3 leads to white moving its pawn and then the knight. black loses)
22. bxc4 Kc5
23. Rc2 dxc2
24. d4+ exd3
25. Nd2 cxb1Q
26. Nxb1

Why would black take on c2 or b1?
Or have the king on b6?

Black can have its king anywhere, but unless he is on b5 or b6, black won't be able to prevent white from moving its pawns and then its knight.
Why would black take the rook on c2? Because Rc2 will prevent the black queen from moving, so unless black wants to unblock c3 pawn, it will have to eat the rook.

Since we all know the solution for the cylinder problem, I post it.
So:
1, Kf2!
Of course this is nothing new, the interesting question is: why? In other words: what are the variations?
I think it is best to play around a bit with the queen and the bishop and try to mate the king in any umber of moves.

Which is one square more than just b6, for starters.

Why would Black want to move her queen?

it only has 2 options: 1) move the king and let the pawn move forward 2) move the queen

Two options can be plenty.
No, the correct answer to my question is: because it wins for Black, whereas 23...Kxc4 is merely a draw.

I just realized that cylinder is checkmate in 4 moves, not 3, lol. For some reason I assumed it is in 3 moves. That makes it a lot easier:
1. Bc5 KC8
2. Bd5 KD6
3. Qc7+ Ke8
4. Qe7#

Your task is to mate in 3.
Surely you must have wondered why the cylinder aspect plays no part in your 'solution' (where I assume you meant to write 2.Bd6 Kd8) above?
Or why none of the hints that we gave you applied?
Or why someone would compose something this ugly and trivial?

This one is still unsolved, too:

Seven moves, but really not so complicated, so everyone can have a go.

hm is it a 3 or 4-mover then?
let me check, i got confused
Hm yes, it's a 3-mover.
I found a nice 4-moves solution, but that does not really matter here.
that is:
1. Kf2 - Kc8
2. Bd6 - Kd8
3. Bg3+ - Kc8
4. Qb1#
1. Kf2 - Ka8
2. Bh6 - Kh8
3. Be3+ - Ka8
4. Qh1#
(too bad it has trivial solutions in 4 moves and that it has a nice 3-move solution as well)
