[Retros] Traditional Christmas Contest of "Stuttgarter Zeitung"

[Jens Guballa]

Dear retro fans,

the traditional Christmas Context of the newspaper "Stuttgarter Zeitung"
has been published. Harald Keilhack invites all retro chess solvers for
this competition.

A German version of the contest with diagrams is available here:

http://www.kaniaverlag.de/htm/Sonstige%20Berichte.html

Here is my translation of the contest:


The following prices are drawn by lots among the senders with correct
solutions of puzzle A + B:

  - Apple I-Pod touch
  - Falk navigation system
  - Philips blu-ray player
  
Senders with correct solutions for all five puzzles will receive a book
price.

After the insertion or after the recoloring of a chess man the resulting
position must be legal (except for puzzle B). Examine how many solutions
do exist.
