21st century chess E 10x9-Spiel. Alle Grundlinienfiguren außer Königen erhalten Reiterkraft (Nachtreiter statt Springer; T+N und L+N als zusätzliche Figuren). Der König zieht zusätzlich wie Equihopper - und kann auch durch Schachs “hindurchhüpfen”; es gibt keine Rochade. Die Bauern werden auf die dritte bzw. siebte Reihe vorgeschoben; die zweite und achte Reihe werden mit Hüpfern besetzt, die jeweils analog zu den betreffenden Grundliniensteinen sind (Turmhüpfer vor Turm, Grashüpfer vor Dame usw.). Alle Bauern sind opting pawns, können also von jedem Feld aus (auch auf das Umwandlungsfeld hin) den Doppelschritt ausführen und en passant geschlagen werden. Bauernumwandlung geschieht auf einer beliebigen der beiden letzten gegnerischen Reihen. Es muss in diejenigen Figur (der eigenen Farbe) umgewandelt werden, die in der PAS auf dem Umwandlungsfeld steht (wird auf dem Königsfeld umgewandelt, so entsteht D+N). [G. P.

-3000 v. Chr. Schon 3000 Jahre vor Christi Geburt gab es Brettspiele in Ägypten, welche sich im Laufe der Jahrtausende wandelten. Aber die ersten schachähnlichen Spiele tauchten erst nach Christi Geburt auf. Wie zum Beispiel in Indien, von wo aus das Schachspiel im 6. Jahrhundert nach Persien gelangte. In Indien hatte es den Namen Tschaturanga, dem Namen der indischen Armee. In Persien erhielt es bereits den Namen Schah, dem persischen Wort für König. Neuere Ausgrabungen und die Uebersetzung alter Schriften lassen vermuten, dass Urformen des Schachspiels bereits 2.500 Jahre vor Christi Geburt existierten. [GH]
