14191 - Stephan Dietrich
Place one white bishop and two white knights on an empty board so they 
have exactly 28 move possibilities. How many solutions?
(Original text: Auf einem Schachbrett stehen ein weißer Läufer und zwei 
weiße Springer (3+0). Wie viele solcher Stellungen gibt es, bei denen 
Weiß genau 28 Zugmöglichkeiten hat?)

14192 - Stephan Dietrich
Place the seven white officers on an empty board. The bishops are on a1 
and h1, the rooks and the queen on a square on the first row, and the 
knights on random squares. White has exactly 64 move possibilities. How 
many solutions?
(Original text: Auf einem Schachbrett stehen die 7 weißen Offiziere. Die 
beiden Läufer stehen auf den Feldern a1 und h1, die Dame und die beide 
Türme stehen auf beliebigen Feldern der ersten Reihe, die beiden 
Springer stehen auf beliebigen Feldern des Schachbrettes (7+0). Wie 
viele solcher Stellungen gibt es, bei denen Weiß genau 64 
Zugmöglichkeiten hat?)

Fairy conditions:
Maximum: Black must play the geometrically longest legal move. Distance 
is measured between the centers of the start- and arrivalsquare.
Ultrapatrol: A piece has only observation powers, no move possibilities 
(including capture and giving check) unless it's observed by a piece of 
the same side.
Kamikaze: When a capture occurs, both the captured and the capturing 
piece disappear
Supercirce: A captured piece can be reborn on any empty square.
Losing chess: Kings are non-royal, captures are mandatory.
Duellist: If legal, a player must make its next move with the same piece 
with which he made the last move.
