White to move. How should white proceed?
Source: ChessToday.net
1. Bd5 Ba5 2. b7 Bc7 3. b8=Q Bxb8 4.Bb7
Q to C3
Q to C3
Wayyyy toooo hard.
I’d try (unchecked) :
1. Bd5 Ba5
2. b7 Bc7
3. b8=Q Bxb8
4. Bb7 Bb5 (eg)
5. Bc6 Bc4
6. Bd5 Bc1+
7. Bb2 Draw
White can try to promote his pawn, but will end up losing it. For example:
1. Bc4 Bxc4
2. b7 Be6+
3. Kh2 Bd2
4. Kg3 Bf4+
5. Kg2 h5
6. b8=Q Bxb8
7. Kf2 {Black has a decisive advantage.}
Instead, white should try for stalemate:
1. Bd5 Ba5
2. b7 Bc7
3. b8=Q Bxb8
4. Bb7 Bxb7 {Stalemate.}
Black can try to avoid stalemate by moving anywhere on his a6 to f1 diagonal, but white’s bishop will oppose him on each one, a situation that can continue indefinitely:
4… Bc4
5. Bd5 Bb5
6. Bc6 Bd3
7. Be4 Be2
8. Bf3 {and so on, and if white BxB a stalemate results}
If black allows the white bishop to capture his bishop, then the white king can stay put and the white bishop can force a threefold repetition or, eventually, trigger the fifty move rule, simply by moving back and forth between two positions. So, if offered a stalemate, black should accept.
Gebelt claims white draws, but actually black wins.
This is supposed to be a stalemate,but comp proved that after 1.Bc8+ black has a very tricky win by moving king and h-pawn with precision and timing.
Craig,
My notes to this problem (from September 11) contain a reference to a suggestion from you that black play 1. …Bc8:
1. Bd5 Bc8
2. Kg2
I have a lot more on this, but I could never conclusively prove the result to my own satisfaction.
Susan,
Can you give us Gebelt’s solution? I would very much like to look at it.

A TRIO OF LITTLE KNOWN
BELORUSSIAN STUDIES
by Dmitri N. Noi
Vaclav Gebelt, who hails from the
small Belorussian town of Lida, has
the FIDE IM Composition title, but
for problems.
Solution to Nl: 1. Bd5 (for b7) Bf2
2.b7 Ba7 3.b8Q Bxb8 4.Bb7 and self-immolation offers on the long diagonal. After Bfl+ 5.Bg2 Bxg2+ 5.Kxg2 we have the familiar ‘wrong bishop’draw.

But, the Bc8 line wins.
Yancey, I am supposing that if white tries keeping his bishop on the long diagonal, black can bring his pawn to h3 and with the king’s support bring his bishop to g2.
I too looked at this when it came out a month ago, and would like to see the proposed solution eventually.
I have let HIARCS 14 have a crack at it and it claims (in my hands) there is.no draw.
