schachmdmt: I was thinking over the translation again. It's not that easy to resolve. You are right that for some historical reason German notation takes its abbreviations off the first letter of the official german name of pieces where in English they don't by the way (eg. kNight). Literal translation doesn't seem the best approach to comply with the current piece naming. It's more a search for names which have a unique first letter (eg. Queen vs Dame [=Lady] instead of Königin [lit. translation]).
So 'Erzbischof' for Archbishop seems to be ok. But I can't find a proper translation for the Chancellor having using this thesis. Kanzler would violate with King. Präsident would be nice but having a President and a King at the same board doesn't look that good. There must be a better term. Probably our German colleagues could help us out here ...
