s#3

(H. Zajic). 1.Td5+? c:d5 2.S:g6+ L:g6+ scheitert an 3.Tc1 und auch das feinere 1.Td4? (droht 2.Te4+/S:g6+) c:b5? 2.Sc4+ Kf5 3.Le4+ L:e4# führt nicht zum Ziele: 1.- Lf beliebig 2.Sf5# Nach dem Schlüssel 1.Ta3! mit der leider nur kurzzügigen Drohung 2.S:g6+ L:g6# " öffnet Schwarz zur Verteidigung Linien, die Weiß gleich wieder verstellt " (AB). " Das ist sicher ein Überbleibsel des (5.) WCCT " (HM). 1.- c:b5 2.Sc4+ (2.Sd beliebig ?) Kf5 3.e4+ L:e4#, 1.- Lf beliebig 2.Sf5+ (2.Sc4?) Ke4 3.d3+ L:d3#. Zu diesen beiden WCCT-Thema-Varianten kommt noch eine fortgesetzte Verteidigung hinzu: 1.- L:e7 2.D:e7+ (2.Sf5?) Kd5 3.Dg5+ Lf5# Lassen wir MR zusammenfassen: " Von den drei Linienöffnungen in Richtung 1. Reihe geben 2 gleichzeitig den Blick auf eines der durch den wBatterie-Springer gedeckten Felder frei, der dann in Siersmanier die schädlichen Linien wieder verstellt, so daß jeweils einer der wBB den sK wieder einfangen und (weit effektvoller als der Springer in der Kurzdrohung) die L-T-Batterie aktivieren kann. Obwohl die 3. Variante mit der Einschaltung der wDame nach Entblockung vom Themaspiel abweicht, empfinde ich also Bereicherung. " Also kurz und knapp: " Gut " (WAB). (16L)

Arnold Beine: Nach 4...hxg1=D#!? in meinen Augen unlösbar, denn die Umwandlungsdame ist doch unverletzlich. Auch nach 5.Kxg1 Lc5+ gäbe es kein Matt im 8. Zug. Oder bedeutet "unverletzlich", dass auch Schwarz keinen Zug ausführen darf, der Weiß zwingt, diesen Stein zu schlagen? Dann würde 4...hxg1=L!! immer noch für Unlösbarkeit sorgen. (2024-02-18)

Welches war die minimale Zahl aller Damenzüge?

Die unglaublich harte Bedingung (minimale Anzahl Damenzüge) bewirkt, dass die wDd1 nicht gezogen hat und die sDh4 eine UWF ist. Um die Stellung aufzulösen, müssen 2 weiße UW auf g8 zurückgenommen werden. Da dort nur Türme entwandelt werden können (Damen scheiden wegen der Bedingung aus!) darf die sDd7 zunächst nicht nach d8 zurückziehen.

A.Buchanan: Two queen moves is enough, as the animation shows. I agree white captures are hxg,axb,bxa/c. bBh promoted on h1, then moved to h4. bBh2 captured in from the left. Black pawn captures something like cxBdxexfxgxh,gxf,dxe. White abcB all promoted and at least one wB on g8. No need for a third D move as far as I can see. (2021-08-03)
Mario Richter: Hi Andrew - the main question is: How do you get the black king home?
In the solution given, after R: 7. a5xLb6 there is a black pawn on e5.
The position can only be unlocked by retracting wKe5-f5. Where exactly is the mentioned black pawn e5 at the moment wKe5-f5 is retracted? (2021-08-03)
A.Buchanan: Hi Mario, I was just responding to H-J's text assertion that 3 D moves are needed. A PG with 3 D moves could not prove that 2 are insufficient, and I find long unanimated PGs too tedious to read through sorry. I now think that the animation must be wrong, but I haven't convinced myself that no solution exists. I must work, but will have a go later. (2021-08-03)
A.Buchanan: OK - we can make sL on queenside and shift to kingside, and I can see that knights (or bishops) can't reach g8 to retract there, so it must be rooks along the 8th rank. So we can't retract the sDd7, and can't shift sTe6. But few Black tempi then. But this is not my kind of retro, and I will give up here. What's the answer: 2 or 3? (2021-08-03)
Mario Richter: My guess is, that the intended solution was 2 Queen moves, but that it it is impossible to get the black king home: R: sLf8, g7xf6 locks e8 from the right side, R: sDd8-d7, sBd7-d6 locks e8 from the left side (2021-08-03)
A.Buchanan: WinChloe has two earlier versions, and the composer was very experienced (200+ retros just in PDB) but I have now looked enough to think this is cooked. Even if we shift sBa forward 2 squares to give us a couple more moves, then all goes well shifting sL & wT to kingside, but we reach a point where sBc7xwBd6, with still sBd5, so the two pawns are the wrong side of one another. What does Rawbats think? (2021-08-04)
Mario Richter: Perhaps it suffices to say what I think?!
With bPa2 instead of a5 it is easy to reach the position with 2 queen moves only:
1. retract R: 1. Te1-f1 g3xSh2 2. Sf1-h2+
2. retract d6xSe5(or d6xTe5)xSf4xBauer_g3 while W makes tempo moves e.g. with wLg1
3. unpromote the S or Te5 on b8 and retract the wPawn to b6, while bPawn a2 retracts to a6
4. uncapture a5xLb6 - now there is no time pressure
5. unpromote wS on c8 and retract the wPawn to c6
6. retract c7xBauer_d6(!)
[this idea was inspired by the question, how the situation mentioned in your comment "we reach a point where sBc7xwBd6, with still sBd5", can be avoided]
7. retract wPawn_d6 to e.g. d3 (but not d2)
8. retract d5xTe4
9. bring wT to g8, sL to f8
10. retract g7-g8=T Dd8-d7 g6-g7 g7xSf6 (or Tf6)
11. unpromote wS or wT on a8
12. the rest is easy to see

Since the author wanted to show a certain combination of C-F-pieces, the above mentioned choices in the uncapture of white pieces still make the modified version of the problem cooked, even if with bPa2 2 Queen-moves suffice.

Zolotarev used the matrix of this problem a lot, search the PDB with
A='Zolotarev' AND G='Retro' AND POSITION='wKf5 sKf3'

And yes, the Composer may be "very experienced" as you put it, but he was also very productive regarding cooks, check e.g. https://www.dieschwalbe.de/ergaenzungena2.htm ...

And one more mysterium: the Retro Corner gives 3 Queen-moves as the solution, s. https://www.janko.at/Retros/Schwalbe/Solutions.htm#9576 (2021-08-05)
Hans-Jürgen Manthey: Es sind 3 DAME-züge nötig !! (und nicht 2 wie A.Buchanan behauptet !)
Zuerst den wK nach f5 dann bK f3 nur möglich wenn der wK kurz auf g5 parkt. jedoch Dh4, Lh3, Tg4 verhindern diesen Plan. Es muß also zuerst bKf3 geschehen. Damit der wK nun nach f5 gelangen kann, darf e5 weder gedeckt (d6) noch besetzt sein (e5). Dank den Hinterstellungen Lh1-Tg2 & Lh3-Tg4 ist nach bxSf6 kein K-Zug mehr möglich ! Da ein g-Springer nicht die Ecke verlassen kann, muß es ein T sein. Auf c(oder a & c) entstandene T (oder S) können auf e5, f4 zwar geschlagen werden, aber es ist keine figur übrig um sich auf f6 zu opfern ! der bK muß aber über d7 oder d8 sein gefängnis verlassen, darum benötigt die ursprungsD 2 Züge(Dc7 oder Dc8 sowie Dd7) + 1 Zug die UmwandlunsDame(Dh4) = 3 Züge !!

Der ungeübte Löser schreckt unwillkürlich vor dieser scheinbar schwierigen Aufgabe zurück. Wenn man aber weiß, daß zum Schluß von der stolzen weißen Bauernkette nicht mehr viel übrigbleibt, ist es gar nicht so schwer.

Adrian Storisteanu: Is the star "*" in the stipulation supposed to indicate a kind of "set play" in the retro part -- in effect a "-1s dann h=1"? Because there is one:
- 1.Ke2xQf3 & 1.Ke2-e1 Qf3-d3=. (2015-08-02)
A.Buchanan: That's a clever interpretation Adrian, I am sure you are right, and it's sound according to Deadpos (2024-01-13)
Adrian Storisteanu: A more precise stipulation would be something like: (-w -s)*, dann h=1 (2024-01-14)
A.Buchanan: Good idea. The convention is that * promises at least one set play instance. (2024-01-15)
