Henrik Juel: The stipulation means 'Retract 11.5 moves, then #1'. All captures were made by black pawns. -1.Ka8 Rb7 -2.Ka7 Rb6 -3.Kb7 Rc6 -4.Kb6 Rc5 -5.Kc6 Rd5 -6.Kc5 Rd4 -7.Kd5 Re4 -8.Kd4 Re3 -9.Ke4 Rf3 -10.Ke3 Rf2 -11.Kf3 Rg2 -12.Kg4, 1.f5# (2003-07-08)
Henrik Juel: This classic seems unsolvable, because both camps have the right to mate, if they can, just after a retraction. And following ... -9.Ke4 Tf3, Black mates with 1... Tc3#. It can be rectified by adding the somewhat lame condition: Black is not allowed to mate; but this would detract from the defensive nature of this problem form. (2005-11-03)
Sally: Weiß will seinen König auf g4 plazieren, um dann mit f5 matt zu setzen. Dazu lenkt er den sT. so, dass er ihm den nötigen Schachschutz gibt. Zurück: 1. Ka8-b8 - Tb7-a7,
2. Ka7-a8 - Tb6-b7, 3. Kb7-a7 - Tc6-b6.....11. Kf3-e3 - Tg2-f2+, 12. Kg4-f3 und vor 1. Bf5#. die sBB. auf dem Damenflügel dienen dem einzigen Zweck, durch ihre Schlagbi-
lanz störende Entschläge des sT unmöglich zu machen.
