If you are familiar with promotion puzzles, you will know what you are looking for here in a general sense. This is a very special kind of promotion puzzle. After you solve it, can you see what is special about it? One last thing- the FEN is important here- pay attention to it.

Yancey, I have found the stalemate but it will be hard to overcome it.
Did you mean this variation?

5.0-0-0 Rc2+
6.Kb1 g1=Q
7.Rxg1 Rb2+
8.Ka1 Kc2
9.d8=Q Bd4
10.Qxd4 Rb1+
11.Rxb1

You have to think outside the box on this one for both sides of the board. I will give you hint that black has stalemate themes in mind that white has to overcome.

Alena, you are correct right up to move 5 for white. Black has a better defense than 5. ...Bc7. I will check back tomorrow and see if you have found it.

At first I thought it was impossible to win. I found five moves and I was stuck. I couldn't guess the sixth move for a long time.

1.f8=Q+ c5
2.bxc6+ Qb4
3.Qxb4+ Kxb4
4.Bxc3+ Kxc3
5.0-0-0 Bc7
6.Rd3+! Kxd3
7.g8=Q Rb8
8.d8=Q+ Rxd8
9.h8=Q Rxg8
10.Qxg8 Ke2
11.f6 Kxf2
12.f7 g1=Q+
13.Qxg1+ Kxg1
14.f8=Q f2
15.Qg7+ Kh1
16.Qf7 Kg2
17.Qxc7 f1=Q+
18.Kb2 Qb5+
19.Ka3
It's a win for white but it's difficult to win.
