Vermutliche Erstdarstellung der Kombination von Le ,Grand und reziprokem Mattwechsel (Autor). Le ,Grand-Komplex plus Reziprokwechsel - gewissermaßen zwei Preisträger in einem! - Die Fluchten fungieren als löserfreundlicher Pilotfilm zu dieser geradezu Cameron'schen Serie (FH). Zwischen der Verführung und der Lösung werden sowohl das Drohmatt und das Variantenmatt nach 1.- K:e6, als auch die beiden Matts nach 1.- Ke4/S:e6 ausgetauscht. Diese 4-fachen Mattwechsel erfordern äußerst filigrane Konstruktionsarbeit (AW). Nach Sortieren des Popeye-Outputs suchte ich einen Viererzyklus der Matts (Droh- und Varianten-) zusammen. Die Zweizüger-Kunst ist gerade in der kubistischen Phase, als nächstes kommt wohl Depressionismus (HR). Als diese nachtwächterfreie Erstdarstellung der Kombination von Le Grand und reziprokem Mattwechsel bei mir eintraf, blieb mir beim Nachspielen vor Begeisterung fast die Luft weg. Ich bin sehr glücklich, daß Daniel die itshape Schwalbe mit diesem Meisterwerk bedacht hat (FP).

Jean Marc Loustau: Here is the complete solution:

Set Play :
1… Bxf3 2 Sxf3# 1… Rxc6 2 Sxc6#

Solution :
1 Sc4~? threatens 2 Qc4# A
But 1… Sd2!

1 Se3? threatens 2 Qd5# B (not 2 Qc4# A? Kxe5!)
1… Rcxd7 2 Qc4# A
1… Bxf3 2 Sxf5# changed
1… Bxe1 2 Qc5# D
But 1… Rdxd7!

1 Se5~? threatens 2 Qe5# C
But 1… Re8!

1 Sd3! threatens 2 Qc5# D (not 2 Qe5# C? Kxc4!)
1… Bb4 2 Qe5# C
1… Rxc6 2 Be5# changed

• 2 Complete Threat Corrections by different pieces, with 4 different threats by the white Queen
• 2 changed mates
• Rich Diagonal/Orthogonal correspondence
Incidentally, a cook try : 1 Re3? (threatens 2 Rd3#) But 1… Sf2! (2022-05-02)
