(A. Beine). Umwandlungs- und Mattwechsel. Etwas störend empfinde ich, dass zufällig noch eine zusätzliche sUmwandlung auftritt, was wie ein ungewollter Pinselstrich im Bild wirkt (EB). Mattbildbastelei, USZ verhindert hier nur Nebenlösungen, gefällt mir nicht (KHS). Zu beachten sind noch die beiden gegenläufigen wK-Rundläufe in den ersten drei Zügen.

Henrik Juel: Natch 3.1 found nothing in half an hour (2018-12-18)
Michel Caillaud: Reprint : H71 p.585, FIDE Album 2001-03

Cooked using Jacobi 0.7.5 with constraints :
1.c4 e5 2.c5 Ld6 3.cxd6 g5 4.d3 g4 5.e3 g3 6.Dg4 c5 7.Sc3 c4 8.Sa4 c3 9.Ld2 Sh6 10.0-0-0 c2 11.b4 Tg8 12.Kb2 gxf2 13.g3 Tg6 14.Lg2 f1=L 15.Ka3 c1=L+ 16.Sb2 Le2 17.Le1 Ld2 18.Tc1 Sg8 19.Txc8 Lc1 20.Tc3 Lf3 21.Se2 Dh4 22.Tf1 Sf6 23.Lh1 Lg2 24.Tf3 Lf1 25.Dh3

Correction : sTg6 to g4 (21...Tg4 instead of 21...Tg6 in the solution)
With the set of constraints used to uncork the cook, Jacobi 0.7.5 finds only the intended solution... (2021-09-20)
Michel Caillaud: The correction sTg6 to g4 was published in StrateGems 99 (p.138, sept. 2022)
It is C+ by Stelvio 0.93 (2022-12-18)

A six-fold oscillation by the theme Bishop, made necessary because no one else can move. Compare with Satoshi Hashimoto, Problem Paradise 1999. (PR Gianni Donati)

The knight undertakes a 12 move captureless roundtrip to prevent twice that the pheni\x queen gives harmful check (this ties the record for the longest captureless roundtrip by a knight). Not computer tested.
Reto: A version of this is C+ by Stelvio 2.0: Ra4-d4 and Qb4-e4 (the content remains the same, but easier to test). (2023-12-17)

Wie erhofft wurde der allgemeine Applaus für diese Miniatur durch keine Vorgängerangabe gestört! Nach 10.Da2 ist „die Ausgangsstellung wieder erreicht und der wSc6 weggeführt: 10.– a:b4#. Das ergibt sich aus dem Satzspiel: 1.– a:b4+ 2.S:b4; der wSc6 muss a tempo weggeführt werden. Und das alles in herrlicher Miniatur-Stellung. Prima.“ (KHS) „Präzise Mattführung im Zugzwang, tolle Miniatur!“ (JB) „Das vermeintliche Satzspiel 1. – a:b4 funktioniert natürlich wegen der Deckung von b4 nicht. Zieht der wSc6, entfleucht aber der sK. Nach einer irren Zugfolge kann schließlich die Ausgangsstellung mit wSf5 doch erreicht werden. Ein Super-Stück!“ (GJ)
(MD1898)

Autor: Das „Satzmatt“ scheitert zunächst daran, dass der wSc6 das Feld b4 deckt. Im Laufe der Lösung erfolgt also eine Umgruppierung dieses Springers unter ständiger Beschäftigung des schwarzen Königs. Im Laufe der Lösung kehren sowohl der Sb4 als auch die weiße Dame auf ihre Ausgangsfelder zurück, wobei die weiße Dame einen linearen Rundlauf vollführt. Mustermatt.

JB entdeckte das folgende Detail: „In a): Der erwandelte weiße Läufer räumt das Mattfeld für den schwarzen König, die schwarze Dame blockt. In b): Der erwandelte weiße Turm räumt das Mattfeld für den schwarzen König, die schwarze Dame ist Schlagopfer.“ Insgesamt gibt es hier „eine Fülle von strategischen Themen, wie z. B. schwarze Opfer, konsekutiver Umnow, Klasinc, Kniest, Koschakin-Thema, Maslar, Platzwechsel von weißem Turm und schwarzem König, Umwandlung in Turm und Läufer bei Weiß, Rückkehr des weißen Turms, ein Mustermatt. Der hohe Aufwand an schwarzen Steinen hat sich hier gelohnt. Schwierig und schön.“ (KHS) Dazu sehen wir noch einen „Rundlauf des weißen Läufers in a).“ (TZ) „Ein großartiger Hit in Sachen Hilfsmattmehrzüger.“ (JA)

Versuch:
1. - d4? 2.Sd6+ Lf1?? 3.S:e4 Ld3 4.Lb8 L:e4#
Der Versuch zeigt, dass die Entblockung des Feldes d3 NICHT DURCH ZUG des wPd3 erfolgen kann, sondern nur durch dessen SCHLAG. (2023-08-03)

Man könnte in der Ausgangsstellung auch den wLf8 nach h6 stellen, dann wäre die Aufgabe auch C+. Dann hätte man einen Nimm-und-Gib-Schlüssel, aber keine Verführung.

1) Der Bg6 MUSS ja wohl im Laufe der Lösung umwandeln, oder? DENKSTE!!! Das wird er nicht!
2) Der Zug Lxc7 MUSS ja wohl mal irgendwann in der Lösung gespielt werden, oder? DENKSTE!!! Muss und wird er eben nicht!
3) Stünde der wLb1 auf c2, hätten wir ein sehr schönes und sauberes #8. Also MUSS dieser Läufer ja mal irgendwann im Laufe der Lösung dahinziehen, oder? DENKSTE!!! Muss er eben nicht!
4) Irgendwie MUSS doch der wLb1 mal nach a2 ziehen, um dann irgendwie auf c4 Matt zu geben, oder? DENKSTE!!! Muss er nicht!
