[Retros] Christmas Contest 2002 of "Stuttgarter Zeitung"

[Jens Guballa]

Dear retro friends,

find below the annual christmas contest of the chess column of the
"Stuttgarter Zeitung" (German newspaper).

Among the contributors of correct solutions for the problems A and B the
following prices are drawn by lots: a micro stereo system, an espresso
machine, a cordless telephone and numerous book prizes.

The compilation of the problems was assisted by Günther Weeth,
Stuttgart. Have fun solving!
