Alice chess

Add the black king so that the length of the shortest proofgame is
a) minimal
b) maximal
What is the geometrically longest queen route in a)?
What is the geometrically shortest queen route in b)?

13766 - Bernd Schwarzkopf
Find an illegal cluster with as many as possible, and as many different 
pieces from the initial game array as possible, on a horizontal line, 
and another white piece on a white square.

Original text: Gesucht ist ein Illegal Cluster mit möglichst vielen und 
möglichst vielen unterschiedlichen Steinen des Partiesatzmaterials auf 
einen Geraden und einem weiteren weissen Stein auf weissem Feld.

13766 - Werner Keym (dedicated to Wolfgang Dittmann's 75th birthday)
Construct an illegal cluster with both kings, two officers and two white 
pawns. The distance between the two kings, the two officers and the two 
pawns is equal, and should be as large as possible.

Original text: Konstruiere ein Illegal Cluster mit den Königen, zwei 
Offizieren und zwei weissen Bauern. Der Abstand zwischen König und 
König, zwischen Offizier und Offizier sowie zwischen Bauer und Bauer ist 
gleich und möglichst gross.
