Lets say white uses his king to take the black pawn on e4. Then white advances his e-pawn and blocks blacks bishop by Bf6. Look at the position

[fen]k7/Pp4bP/1P3B2/4P3/1p3K2/1P6/8/8 w - - 0 1[/fen]

Then move the king around to g6 or g8

and 1-0

Your position is a win for white no matter who moves, but how do you actually get there without allowing Black to capture either the e pawn or the Bishop?

1.h8(N),Bxg7 2.Ng6,Bh6 3.Ne7,Bxe3 4.Nd5,Bxb6 5.Nxb6,Kxa7 6.Nd7 wins.
Something like that maybe?

2...Bf6

Actually ...BxB loses to e6! Zugzwang

EDIT- Sorry, you meant on Bf6 before e5. Yes, that is the same defense for black that I saw, making that position impossible to reach.

Yep.

But getting the bishop to f6 in that position is extremely hard..

If black temporizes between h8 and g7, then whenver white puts anything on that diagonal, black snatches it off. You can't reach your position. It'd be nice if you could though.

Ok,let's try again.
1.h8(N),Bxg7 2.Ng6 and now the knight will always reach d5 winning the game,no?
And 2...,Bd4 fails on exd4.

Or am I still missing something?

[fen]5K2/k7/4P1p1/8/8/8/4b3/8[/fen]

1. Ke7! g5 2. Kd6! g4 3. e7!! and now if Black tries 3...Bb5 then 4. Kc5 forces black to make the decision. He can let the Bishop drop and both sides Queen, or he can blockade the pawn, when 5. Kd4! gets back inside the square of the pawn. =

I didn't miss that,I said it fails.It fails cause the knight mates on c7 right after black's e-pawn promotes.

edit: Hehe,I see that's been settled allready 🙂
