Nr.4444 (Fiedler): „Diese sogenannte ‚Gravur‘ – ein Problem mit 8 bis 10 Steinen – beinhaltet ein überraschendes Springeropfer am Anfang zwecks Linienräumung für das bekannte Ende.“ (K.Keller, Ulm) Das starke 1...c1D+! im Satz muss verhindert werden, aber 1.Df5? ist patt „Aber hier hat mich das Springer-Opfer-Manöver zu Beginn der Lösung doch überrascht und gefoppt“ (H.Suwe, Winsen): 1.Sc3+!

Henrik Juel: double threat 2.Dxa5+,Lxd3, many duals and mate duals (2022-10-04)
Ulrich Voigt: Ist eine Drohung, die aufgrund von Zugzwang nie verwirklicht werden kann, tatsächlich eine Drohung? Es gibt keinen schwarzen Zug, nach dem 2. Lxd3 zum Ziel führt. Kann man in einer solchen Situation überhaupt von der Drohung 2. Lxd3 sprechen?

Die einzige "echte" Drohung ist 2. Dxa5, und nach den beiden Paraden 1... Kxb5 oder 1... Lxb5 findet Popeye keinerlei Duale oder Mattduale. (2022-10-05)
Henrik Juel: I agree that 2.Lxd3 is a threat only in a formal sense, Ulrich
If you disregard it as a threat, the problem is OK (2022-10-05)
Mario Richter: Can somebody please explain in what sense this is a "Zugzwang Goal"-Problem? (2022-10-06)
Dieter Berlin: Zugzwang-Goal wird bei Eingabe als Zugzwang-Ziel bezeichnet. Diese Bezeichnung hat m. E. den Vorteil, dass Zugzwang nicht direkt nach dem Schlüssel vorliegen muss wie in 'alten Zeiten', sondern wie in diesem Fall der Weiße auf Zugzwang nach dem 2. Zug Dh4! hingearbeitet hat. (2022-10-07)
Mario Richter: Dieter, bist Du sicher, daß Deine Interpretation von "Zugzwang-Ziel" mit der PDB-Definition übereinstimmt? Wenn ja, was ist dann bei Dir das "X"? (2022-10-08)
