Sally: Loyd-Gedenkturnier 1961 , Spezialpreis.
Nach 1. Sxc1 wäre S. patt!. Es geht darum, Patt zu verhindern,
da ja die s. Dame (schwarzer Siegfried), nie geschlagen werden kann, sondern nur wenn W. eine s. Zugmöglichkeit schaffen kann. Daher :
1. Dxh6!(droht 2. Dxc1#) - Dxh6+,
2. Kg8 (droht 3. Tb1#) - Dc1,
(Auf ein Schachgebot (2. - D+, 3. K[B]xD), wird die s. Dame einfach geschlagen, denn durch das Damenopfer ist der Zug
"h7-h6 möglich geworden)
3. Sxc1 - h6!
4. Tb1#.
Falls :
1. - Da3+, so :
2. Dd6 (Rückkehr) - Dxd6+,
3. exd6 - h6!,
4. Tb1#.
1. - Dxc2,
2. Dc1+ - Dxc1,
3. Sxc1 nebst.
4. Tb1#.
Schachprovozierendes Damenopfer auf "h6", um durcg Beseitigung des s. Bauern h6 den s. Bauern h7 bewegkich u machen und damit die s. Dame ihres Siegfrieds Charakters
zu berauben. (2017-8-17)
Henrik Juel: C+ by Popeye 4.61, except for duals after other defenses than the main one, 1... Dxh6+ (2017-8-17)

Mario Richter: Complete Stipulation: Black, playing first, retracts his last three moves and White his last two moves; in the resulting position Black can mate immediately. (2010-12-4)
Mario Richter: The type of the uncaptured piece in -3.e5xf4 is not determined. Perhaps in analogy to "geduldeter UW-Dual" one could speak of a "geduldeter Entschlagdual"? (2010-12-4)
Henrik Juel: Maybe Pf4 should be on f5 (it is not needed on f4, because e3 is doubly covered already). Then there is no dual, 3. f6-f5. (2010-12-4)
Henrik Juel: Please delete the preceding comment and this one. d4 must be covered in the mating position. (2010-12-4)

One of the few dual-free full-length variations is
1... De5+ 2.Kxb3 Dc3+ 3.Lxc3#
Correct key by Popeye 4.61, but too many duals for my taste (2015-9-12)
Henrik Juel: The idea may be tries
The other six possible moves by Sd6 fail on 1... Dg3! (2015-9-12)
Henrik Juel: 1... Dd6 is not dualfree: 2.Kxb3+,cxd6 (2015-9-12)
Rainer Staudte: Benkö: "Im Jahre 1950 gingen in B.C.M. über 500 Lösungen aus aller Welt ein, von denen die Hälfte falsch waren. Im Jahre 1992 war M. Tal in Buenos Aires und ich zeigte ihm dieses Problem. Er irrte sich zweimal, dann wurde er ernst und fand die Lösung. Stellen Sie sich vor, wie stolz ich war."
