A.Buchanan: There is a pile of Broecker schema problems, and some similarity, but at least this one is directly anticipated by P1222498, by Broecker himself, in 1892. It is identical except has added an unnecessary sBa7. The date of this one is not given, but judging from the problem number of this magazine (11076) it must have been published in the 1970s.

Selfmate posted in chess.stackexchange by someone who had been given this by a friend. Doesn't know how many moves. Not 100% certain that there is a solution. Popeye v4.79 says no solution in 12 moves (1.5 hours).
Henrik Juel: With Black to move, 1... Lc6 2.Dh8 Lb7 3.Lc6 Lxc6#
With White to move, I see no selfmate (2018-04-25)
A.Buchanan: It's a very interesting position. Assuming wQ does not leave 8th rank, there are a set of 15 WTM positions to orbit between, with the distance between the bishops a function of the location of wQ. However, White does have the extra resource of triangulating wQ off the back rank, and then returning with check if bLb8 moves. How to do this safely though? (2018-04-25)
Olaf Jenkner: So ist die Aufgabe wahrscheinlich unlösbar. (2018-04-25)
A.Buchanan: Olaf, thanks for your authoritative confirmation. I certainly couldn't see any way that wQ could help White.
Now: this was posted by a Brazilian math student, who said he got it from a friend a year ago, and had not been able to solve it. After 24 hours of discussion, the problem was deleted!
So I don't know what the parentage of this problem is. But the basic set-up is interesting, and I wonder if there's any fix possible? (2018-04-25)
Olaf Jenkner: Maybe the student's friend gave a wrong position. 16 similar can be found this way:
g='s#'and (position='sKa8 sLb7 sLb8 wKh1'or position='sKh8 sLg7 sLg8 wKa1') (2018-04-25)
Mario Richter: I'm not a selfmate expert, but how about the following idea: Start with 1. Dh8 Lc6 2. Dh6 Ld6! 3. Lxc6+ Kb8 4. Dxd6+ Kc8 5. Dd7+ Kb8 6. Df7 Kc8 7. Dxa7, promote a rook on a8, force the following position:
w: Kh1 Dh5 Lc6 Tf5
s: Kg3 Bh3 Bh2
(FEN: 8/8/2B5/5R1Q/8/6kp/7p/7K),
then s#1 by 1. Lg2! hxg2#
My estimation is that the complete Scenario will not take more than 23 moves ... (2018-04-25)
A.Buchanan: @Olaf oic so this thing has a name "the Broecker schema". Lots more with that keyword Broecker-Schema (2018-04-26)
A.Buchanan: @Mario: I haven't had a chance to go through the full list of your moves, but I don't think Black needs to ever move Lb8. Wherever wD is, indicates the set of legal moves for sL on the main diagonal relative to wL. If wD is on 8th rank, there is only 1 safe location. After 2. Dh6, sL can go anywhere except adjacent to wL (else 3. Dh8!) So here 2. ... Lb7! is ok (If 3. Df8? Lxde5+! etc). (2018-04-26)
Mario Richter: 1. Dh8 Lc6 2. Dh6 Lb7! 3. Dc1 Lc6 4. Da1! Lc7,Lb8~ 5. axb7+ and continue with the plan explained above (2018-04-26)
A.Buchanan: @Mario: OK your ingenious answer is like finding an endgame study solution to a #n. We don't know the intended length of this s#n but I suppose it must be finite. Most of the longer problems (n10) in PDB using this matrix are cooked, by the way.
@Olaf: who is Gustav named after? Not Von Broecker? :-) (2018-04-26)
Olaf Jenkner: https://de.wikipedia.org/wiki/Gustav_Ginzel (2018-04-26)
A.Buchanan: @Mario: I don't follow this second series of moves 1. Dh8 Lc6 2. Dh6 Lb7! 3. Dc1 Lc6 4. Da1! Lc7,Lb8~ 5. axb7+. If 5. axb7+ is going to happen, then Black must have played 4. ... Lb7 not moved Lb8. And then axb7 is mate. How to force Lb8 to move so that axb7+ is not mate is really the whole point. (2018-04-27)
A.Buchanan: How about 1. Dh8 Lc6 2. Da1 Lb7 3. Lc6 Le5 4. axb7+ Kb8 5. D~ etc? (2018-04-27)
Mario Richter: I forgot one move pair. So again: The main plan is to force Black's dark-squared Bishop to leave b8 and then force bK to g3 in such a way that by placing a White Piece on g2 Black is forced to mate by h3xg2#.
Black's defense consist of preventing sLb8 from moving as long as possible.
1. Dh8 Lc6 2. Dh6! Lb7! 3. Dc1! Lc6 4. Da1! Lb7 5. Lc6! Le5,Lb8~ 6. axb7+ Kb8. Now the main plan can be executed and my estimate is that 22 more moves suffice (making the whole thing a s#28).
A sample continuation: 7. De1 Lc7 8. De8+ Ld8 9. Lf3 Kc7 10. De5+ Kd7 11. b8=D Lb6 12. Le4 Ld8 13. Dg7+ Ke6 14. Dxd8 a5 15. Da7 a4 16. Dd5+ Kf6 17. Dd6+ Kg5 18. Da5+ Kg4 19. Df5+ Kh4 20. Lb1 a3 21. Dd4+ Kg3 22. Dfe4 a2 23. Dg2+ hxg2#
So my question @Olaf+Co. is: Is Gustav able to solve the position after 6. ... Kb8 as a s#16, s#22, ...? (2018-04-27)
A.Buchanan: I think 2. Dh8-a1 directly. Also note the other line 2. Da1 Le5(Lb8~) 3. Lxc6+ Kb8 etc, 4. D~ ending with promotion on a8. (2018-04-27)
Gerald Ettl: Ich vermute, dass auf c8 ein wT steht. Doch nach 1.Le4 Lc6!, 1Lf3 Ld5! und 1.Lg2 Le4 sehe ich keine Loesung in 8 Zuegen. (2018-04-27)
Gerald Ettl: ok, eigentlich egal, ob wT oder wD. Aber auf normalem Weg, so dass der sL matt gibt sehe ich keine Loesung. (2018-04-27)
