play all play one stop play next play all
Henrik Juel: The Draw (by repetition) is part of the stipulation
Without it, there would be cooks, e.g.
1.Sg1-f3 Sb8-a6 2.Sf3-g1 Sa6-b4 3.Sg1-f3 Sb4-d5
4.Sf3-g1 Sd5-e3 5.Bh2-h3 Se3-g4 6.Th1-h2 Sg4xh2
7.Sg1-f3 Sh2-g4 8.Sf3-h2 Sg4xh2 9.Ba2-a3 Sh2-g4
10.Bh3xg4 Bh7-h6
and short solutions, e.g.
1.Sg1-f3 Sb8-a6 2.Sf3-d4 Sa6-c5 3.Sd4-b3 Sc5xb3
4.Sb1-a3 Sb3-d4 5.Ta1-b1 Sd4-f5 6.Tb1-a1 Sf5-g3
7.Sa3-b1 Sg3xh1 8.Ba2-a3 Sh1-g3 9.Bh2xg3 Bh7-h6
10.Bg3-g4 (2018-12-25)
Henrik Juel: The shortest solution (without Draw) is unique
1.Sg1-f3 Sb8-c6 2.Sf3-e5 Sc6xe5 3.Bh2-h3 Se5-g4
4.Th1-h2 Sg4xh2 5.Ba2-a3 Sh2-g4 6.Bh3xg4 Bh7-h6
and identical to the first 6.0 moves of the intended solution
Why could the subsequent triple repetition not be achieved by rook moves?
Probably because the position after 7.Ta2 Tb8 8.Ta1 Ta8 is not considered to be a repeated position, as the castling rights have changed (2018-12-25)
A.Buchanan: Yes that's exactly it Henrik: the surviving rooks are nailed to their start squares (2021-06-05)

play all play one stop play next play all
White pcs: dxexf5,hxBg. Black none. Assume that Black can still castle. White can't have just played h4xg5 as sBh2 would be blocked. White might apparently just have moved D,Se5,Td4,Tc3,g4-g5,a5-a6,e3-e4 or e2-e4 but what might Black have played before? Only the last allows a move sDf1-e1. So set up for AP Type Petrovic is OK.
Cook: 446 candidate h#2
However 27 have no ep, while 59 have both ep & castling.
So a total of 86 viable solutions, 85 of which must be cooks.

Cook: Retro logic doesn’t work
(As well as major dual)
So unsound
SCHRECKE: Konnte zuletzt nicht auch 0. ... Kg7-h6 geschehen sein? (2021-02-15)
A.Buchanan: I think the diagram must be wrong. Not only does the retro logic fail, but also there is a dual 2. Df3+,Dg4+. It's not in WinChloe. (2021-02-15)
Mario Richter: An additional white Pawn e7 would justify the epkey, but not prevent the mentioned dual. (2021-02-16)
VL: We might shift wPf2 to f3 against the dual. Or exchange Bf6 with Pf2 and add wP on f3 (instead of e7)... (2021-02-16)
A.Buchanan: Shifting wBf2 to f3 leads to short cook solutions 1.Dh2. However I think 8/5p1p/4NB1k/3PPKpP/4P3/8/5PP1/2Q5 fixes the retro issue, and it's C+ by Popeye, with still ideal mate! The composer Tomislav Petrovic is still alive but would be very old (90). Is he still active? (2021-02-17)
A.Buchanan: By the way, if you query for k='foo', that will always return uses of the keyword "foobar". It's just checking for the prefix. If you omit k='foo', then that will also block "foobar". Therefore if we tag with "en passant as key", then we should not tag with "en passant" too. Both keywords should exist, and over time we may refine uses of "en passant" to be more precise.
Because of the sensible way prefixes are handled in PDB, this is a different situation from tagging a problem as both "ceriani-frolkin" and "prentos", which we should do.
On this general subject, when counting instances within a single problem, we should always use Gerd's excellent mechanism of parameters "foo:1" etc, rather than having separate keywords "foo 1", "foo 2" etc. Otherwise the set of keywords becomes unmanageable. (2021-02-17)

Welches waren 4 Einzelzüge?
R: 1. fxe6ep+ e7-e5 2. Kd4xSc5 Se4-c5
play all play one stop play next play all
In 'Probleme für Tiger' nachgedruckt mit der Forderung: "Welches waren die letzten zwei Züge von Schwarz und Weiß?"
Axel Steinbrink: Hinweis von Bernd Schwarzkopf: Der letzte Zug ist nicht eindeutig: auf c5 hätte auch ein beliebiger schwarzer Stein geschlagen worden sein können. (2020-12-20)
Henrik Juel: I think that any white man (not black) could have been captured on c5
But the last 3 single moves are determined (2020-12-20)
Hans-Jürgen Manthey: die Lösung ist eindeutig!
Der wK muß d4xc5 geschlagen haben, und da der wK auf d4 im schach stand und der sT weder von a5 noch von a3 gekommen sein konnte, muß der zug sSe4-c5+ vor dem wK schlag gewesen sein. Also:
1... Se4-c5+ 2. Kd4xc5+ e7-e5 3. f5xe6ep+ (2020-12-21)
A.Buchanan: Hi Hans-Jürgen, Sie haben Recht mit den ersten "dreieinhalb" Zügen. Henriks Idee ist, dass Ne4-c5 ein Schlag eines unbekannten Steins sein könnte. Normalerweise müssen wir das genaue Diagramm vor dem Zug kennen, um einen Zug klar zu charakterisieren. (2020-12-21)
Hans-Jürgen Manthey: A.Buchanan ist es denn wichtig ob ein w Stein auf c5 geschlagen worden ist, oder nicht ? Auf jedenfall muß ein sS von e4 nach c5. (2020-12-21)
A.Buchanan: Hans-Jürgen, heute halten wir es für wichtig, weil Wir haben Rekorde für z.B. "Letzten 17 Einzelzüge?" brauche also eine einheitliche Definition von "Zug". Manchmal ist die Forderung eines älteren Problems auf diese Weise ungenau, aber nicht kaputt. (2020-12-22)
Hans-Jürgen Manthey: Ich hätte da eine Idee:
das Diagramm wird vervollständigt mit wBa2,b3,c2,d2,e2,g3 wLh1 wSb1,g1 wTc1 wDd1. Nun ist es nicht mehr möglich eine weiße Figur zu Schlagen! :-) (2020-12-23)
Mario Richter: Shouldn't the stipulation be: "Welches waren die letzten 4 Einzelzüge?" or "Letzte 4 Einzelzüge?
And, imho, the problem is cooked. Jans-Jürgen's suggestion would make the problem correct, but at the cost of much too much material. (2020-12-24)
A.Buchanan: The stipulation field in PDB has always been used to communicate the solvable intent of the composition. Stipulations have been rewritten by Gerd or others where necessary. What we lack is an Originalforderung field. But we can fake that in the Comment field. It hardly breaks the problem to change stip to 3 from 4 (2020-12-25)

Henrik Juel: Natch 3.1 did not even find the solution in some 8 hours! (2018-12-19)
A.Buchanan: a rare home-and-away-base problem (2018-12-19)
A.Buchanan: What's it called when a pawn promotes onto a square that another promoted pawn has already been captured from? Anti-Pronkin I think. (2018-12-19)
Henrik Juel: No Andrew, Anti-Pronkin is the paradoxical case of an original officer moving to the promotion square
Here we have two T promotions on h1 (and one on a8) (2018-12-19)
A.Buchanan: Thanks Klaus. If we repopulate Lc1, i.e. Rnbqkbnr/p1pppp2/8/8/8/8/1PPPPP2/RNB1KB1r then is the following sound as BP in 12.5? Same first 9.5 moves then 10. ... gxh2 11. Kf1 Txe1+ 12. Kxe1 h1=T+ 13. Lf1 (2022-06-08)
Moldenhauer: Hi Andrew, die neue Stellung mit Lc1, BP in 12.5 wird in ca. 47 Min. von Euclide 1.11 als gekocht gewertet.
Natch 3.3 habe ich abbrechen müssen bei der Auswertung. Zuviele Daten! (2022-07-13)
A.Buchanan: Hi Klaus, danke noch einmal. Vielen Dank - das habe ich erwartet, aber ich denke, es lohnt sich, das zu überprüfen, um die Konstruktion besser zu verstehen. (2022-07-14)

Sally: ( V. ) St. Schneider gewidmet.
Hätte Schwarz 2 Wartezüge, ginge 1. Ke6, 2. Kxd5, 3. Lc4#!
Jedoch hat sich Schwarz in seiner Patt- Burg veschanzt. Hätte er wenigsten einen, ginge 1. Th3, 2. Bg3, 3. Bg4+, 4. Bg5 -Bhxg5, 5. Ke6 usw. Aber er hat keinen. Daher der Vor-
plan : Td3? -Kc4, 2. Td1+ - Kb3 (3. Th1 - Le1, 4. Th3+ -Lc3), geht so lange nicht, wie der Lf1 noch den Weg versperrt.Also zuerst den den Läufer umpostieren. 1. Ld3?/Ld1?, 2. Le2+/Lc3 sähe gut aus, ginge aber nicht 1. - - Ld2! mit dem Angriff auf dem Turm. Der Turm gehört zuerst
auf ein weißes Feld der 3. Reihe.
