White to move and win.
8/B7/k7/2K4B/8/N7/8/2b5 w – – 0 1
Hidebrand, 1963
Wow, two pieces en prise! And I don’t see a way to save them both! Given the problem, the piece white must save has to be the knight since mate with the two bishops won’t work due to interference from black’s remaining piece.
I would try:
1. Kc6 Ka7 (forced as 2. Bb6 wins)
2. Nc4
and now black has fewer options for moves. The bishop is forced to f4/g5/h6 if it moves and the king can be corralled into the corner. However, I really need a board for this problem. There are just a lot of different variations.
I tried to make he sleak 1.Kc6 work, however, after 1…Kxa7 [1…Bxa3?? 2.Bb6 and white wins] I do not know how to continue. It “feels” good but where is the win?!
The alternative 1.Nb5 Be3+ also looks interesting but I could not find a win after either 2.Kc6 or 2.Kb4. Somebody please enlighten me!

1) Bg3- B X h6 +
2)Kf3–
Then Black cannot move his king. He just has to move his balck bishop to some square to complete the step.
Then Bd2+.
Am I right…

it is tricky! and challenging indeed! ^_^
Hmmm. I must be overlooking something as this looks not as tricky to me!? There are not many moves that looks senseful and the short forced line is easy calculated.
1. Bb6! and the threat 2. Kc6 (e.g. after 1. -, Bxa3+) 3. Bd3# forces 1. -, Be3+ (or Kb7 after which white simply plays Nc4 and keeps the material advatage) 2. Kc6, Bxb6 3. Be2+ and now white wins the bishop after
3. -, Ka5? 4. Nc4+ (fork) or better
3. -, Ka7 4. Nb5+, Ka6!? (to keep in contact with the knight as long as possible) 5. Nd6+! followed by the fork Nc4+ or Nc8+.
It’s cute. I hope the solution is right!

Bb6! does the trick.
If KxN, it is easy. Kc6 and mate with the white squared Bish.
If B check, Kc6, Bxb6, it is slightly harder. Be2+, Ka7 (If Ka5, Nc4 wins the bishop), Nb5+, Ka6, Nd6 discovered check and no matter which square Black chooses there is a knight fork. After that we just have to hope white remembers how to mate with Bish and Horse
oops Bb6

1. Bg6
if
1. … Bxa3+
2. Kc6 and 3. Be2#
if
1. … Be3+
2. Kc6 Bxg6
3. Be2+
now if 3. … Ka5, 4. Nc4+ and 5. Nxg6
or if 3. … Ka7
4. Nb5+ Ka6 (else the bishop and the game is lost)
5. Nd6+ Ka7
6. Nc8+ wins back the Bishop on g6.
N/B/K vs K is a win, see

I’m not worried about the knight..Bb6! Bxa3 Ka6 seems to win, since the existence of the black bishop takes stalemate out of the equation and black cannot do anything to stop Be2 mate. But I’m too lazy to look find something if black does not take the knight 🙂

1. Bb6 .. Be3+, “better” than Bxa3 which loses earlier without putting any trouble
2. Kc6 .. Bxb6
3. Be2+ .. Ka7 or knight fork at c4
4. Nb5+ .. Ka6 or loses the B instantly
5. Nd6+ and after one or two moves follows a fork.
1.Bb6 (threat Bc8# save the N)
1…Be3 is challenging
2.Kc6 forces Bxb6
and now White has a BN-B win
3.Be2+
3…Ka7 or the N gets the B
4.Nb5! Ka6 – to save the B
5.Nd6+ and now N forks K/B
Whose study is this? Let us thank the artist for their artistry.
I keep getting the files mixed up!
Meant 1. Bb6 but hallucinated and typed 1. Bg6.
Yesterday, meant 1. Bc2, but typed 1. Bb2.
Getting old…
Agree with those of you who think 1.Bb6 is the way to go.
You’re all correct, guys.
1. Bb6 is effectively the key move.

Hildebrand, Schach Echo, 1963, #398
Hildebrand composed since 1945 and is rather prolific. Is he alive now? I don’t know, but in my trusty study database (Van der Heijden does a great work by collecting studies), there is a joint composition with Katsnelson in 2004 in Springaren. Any news from Hildebrand?
