18186 (H. Brozus). a) 1.Ke3! Kd5 2.Sd6 Ke5 3.Se8 Kd5 4.Kd3 Ke5 5.Ld6+ Kd5 6.e4#. Für den Teil a) hat Kurt Keller ein Vergleichsstück yacpdb.org / #366782 [366782=P1382503] von Waleri Ivanov mit der Quelle Sem shahmatnyh not von 2009 recherchiert: #5, wKc4 wLc8 wSe3d5 wBd2 sKe5, 1.Sf5!

An Aufgabenteil a) habe ich mir die Zähne ausgebissen – der erhoffte Exzelsior-Marsch des e-Bauern war leider wenig erfolgreich.“ (JS [Jochen Schröder]) Den von Jochen Schröder erhofften Exzelsior zeigt der von Kurt Keller dankenswerterweise gefundene Vorgänger P1140062 von Lajos Riczu aus Magyar Sakkelet von 1978. #6, wKd3 wLe6 wSe4g5 wBa2 sKf4, b) wBa2?h2, a) 1.a4 Ke5 2.a5 Kf4 3.a6 Ke5 4.a7 Kf4 5.a8D Ke5 6.Db8#, b) 1.h4 Ke5 2.h5 Kf4 3.h6 Ke5 4.h7 Kf4 5.h8S Ke5 6.Sg6#. „Im Duo gefälliger leichter Rex-solus mit weißer Unterverwandlung in einer Variante. Schwarz hat dabei allerdings nicht viel zu sagen.“ (KHS [Karl-Heinz Siehndel])

  • Author – Hartmut Brozus (Berlin, Germany)
  • Hartmut Brozus legt (18186) eine löserfreundliche Aufgabe vor, bei der es mich nicht wundern würde, wenn es einen Vorgänger geben sollte.
