I doubt it is. But Im not sure which moves you are playing first :( . If you numbered it I could probably confirm if theres another way. But its definitely not the solution I have.

First solution wont work cause you forget that the Black bishop can block the alst check by moving it right in front of it .
Code:
Bxe8+         Kxe4          
Bg6+          Kd4           
Rf3+          Be5

Second Solution won't work cause you don't have a check which would mate the king at this point.

Code:
Bxe8+         Kd4           
Rf4+          Kd3           
Rxa2           ?

Solution
If you've been looking for use of those discovered checks using either Rooks or Bishops your intention is good but you won't be able to mate in 3. I order to do that as I said you need to look at a very ridiculous move.

Theres a numerous amount of moves the opponent can make however they all end up in the same place. Checkmate within 3 :) . Post your move list if you have a question. Otherwise its workable from here.

wtf?
I thought of Ke2(threatening Ke3), even posted the solution. Then saw f1=Q+ leads to an unescapable double check. So I deleted my post..

1. Ke2 f1=Q+ , Kxf1 Rf2+ - no mate here
2. Ke2 f1=Q+, Ke3 Qe1+ - no mate here...:confused:

Edit: okay figured it out.
2. Ke2 f1=Q+, Ke3 Qe1+ , Be2++ :)
Or 2. Ke2 f1=N+, Kd3 .. leads to mate

Lol I told you the solution wasn't one of the sanest moves. In the beginning no one would let the pawn go through to get queened :) .

Mate in 4.

Well, I seemed to have missed some action out here! :)
h7 is the only best move at this point and its obvious coz the king is also forced to move.

but, i see 5 moves max,
1) h7 Kg7 2) h8Q+ Kg6 3) Ncd5 Kf5 4) Qe8 Kg5 5) Rh5#

??
Is there any other possibility forcing the opponent king to check mate in 4 moves??

It doesnt seem that anyone is interested :( . Oh well the answer starts by moving Knight to B1. You can easily calculate the rest.

You are Wrong I guess.
Let's see:
The black king is stale.
In reply to move 1) Nb1 c3 is the only possible move.
White makes 2) Rg1 (only possible relevant move I could think of).
For which 2) Rg1 c2+ is the reply.
Now comes the beauty...
if 3) Kd2 or 3) Ke1, then Black responds c1Q+ if 3) Ke2 then c1N+
followed by,
4)Ke3 Nd3 5)Rg8#

So, I guess its not 4 move move by forcing.
I meant the bold letters for better significance sake alone.

You need to look deeper.

In reply to move 1) Nb1 c3 is the only possible move.

Yes very true. The reason you are not opening the path for the King is that it will throw away any chances of mating in four.

Here are the moves.
Code:
Nb1     c3

Moving the Knight is a must since the King is boxed in.

Code:
Ke2     c2

You are moving the King for two purposes. First to prevent it becoming check on next move and two to give the Rook access to the horizontal row.

Code:
Rc1     c2xb1

This is the fun part. You see its not stalemate. The pawn can still take the Horsie and promote to a queen or whatever. However it does not give him a check on promoting and hence You are free to move whatever you want. If you cut the queen your dead. Its a stalemate. But if you play the next move the game is over.

Code:
Rc8

Checkmate. This is a Forced Mate in 4 moves.

Rc1     c2xb1

Ok now, you are wrong.

As Black, I wouldn't play c2xb1. I would promote the pawn to Knight to give a check... It extends the play by 1 more move. I already indicated it in the last reply. Read it carefully and analyze it. You Can not force mate in 4 moves. The white king is susceptible to check by the pawn promotion either to queen or knight where ever he goes...!!

Unfortunately , you are wrong.

Read the move correctly. Draw it on a paper and you will see that I am right. This is a forced mate. The rook is in front of the pawn. The only LEGAL move you have is to take the horsie. I shall illustrate it with pictures below .

I will post screenshots from my Friends laptop . Right now Im on Linux and its hard to do it in Gimp for me.


Original Position

*img205.imageshack.us/img205/5348/nunn5nh8.jpg

Step 1.

Step 2.

Step 3 - (White only moved in the picture. Now its Blacks move)
*img352.imageshack.us/img352/7990/step4ln0.jpg

Once the rook is in front of the pawn the ONLY move you have is the Pawn to Take the Horse. Next move Rook all the way to the Kings row which checks King. Game over. This is a Forced Mate. The reason I call it Forced is cause once I play the opponent has no alternative but playing the moves I listed above.

I just played the position in Fritz 11. It couldn't find a solution in 4 moves...
Just tell me this... Nothing else is necessary...

Instead of playing c2xb1 in your moves, why shouldn't I play c1N+??

How can you play C1N+ ???? Theres a rook in front of it. Pawns can only capture Diagonally.

c2xb1 Means Coin on c2 moves to b1 by capturing whatever is on it. I havent written the full algebraic notation since I don't know what coin the person wants to promote his pawn to.

You cannot play c1 since pawns can only capture diagonally. DId fritz let you capture c1 while rook was in front of it? Cause if it is you should report the bug. Pawns can only capture diagonally. The only exception is en passant and that too captures daigonally.
