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.
