Hallo!

Habe mein uraltes Eröffnungsbuch (echtes Buch aus Papier!) rausgekramt, und 50 Stellungen zum Testen erstellt. Diese Vorgabestellungen sind ein halbwegs ausgewogener Querschnitt durch die häufigsten Eröffnungssysteme und es sind recht kurzzügige Varianten, deren Endstellungen sowohl von Fritz als auch von Rybka ziemlich neutral bewertet werden. Finde ich besser als die Noomenvorgabestellugen, wo einige Endstellungen nicht gerade sehr neutral bewertet werden bzw. die Nunn-Stellungen, die mir zu weit fortgeschritten sind und oft schon recht klare Abspiele erzwingen.

Ich häng hier das PGN-File rein, einfach per Drag & Drop in ein .pgn-Texteditorfile ziehen. Sollte klappen.

Gruß - S.Pohl
