what does Aulic Council and Hofburg have in common?
Hofburg The Hofburg is the former imperial palace in the centre of Vienna, Austria. Built in the 13th century and expanded in the centuries since, the palace has been the seat of power of the Habsburg dynasty rulers, and today the official residence and workplace of the President of Austria. It was the principal imperial winter residence, as Schönbrunn Palace was the summer residence.
Allumwandlung Allumwandlung (German for "complete promotion", sometimes abbreviated AUW) is a chess problem theme where, at some stage in the solution, a pawn (or sometimes pawns) is promoted variously to a queen, rook, bishop, and knight. Allumwandlung's main requirement is promotion, either a white pawn or a black pawn. A Babson task may appear if both pawns are spotted in an individual problem, corresponding one another.
