```Hi,

Sorry for posting the results of the contest so late.

The result is available in German here:
http://www.kaniaverlag.de/htm/Weihnachts2014.html

Here is a brief translation:

The lots were drawn among 31 senders with at least "1.5 points out of
2" (problem A + B).

The winners are:

1st price (Apple iPod Touch): Peter Wauschkuhn (Stuttgart)
2nd price (Falk-navigation system): Jens Guballa (Tamm)
3rd price (Apple iPod Nano): Jürgen Berthel (Stuttgart)

Nine experts send completely correct solutions for all four problems.
These are:

Olli Heimo
Hannu Lehto (both from Finland)
Günther Büsing
Dietmar Fauth (both from Munic)
Rainer Kuhn (Worms)
Mario Richter (Berlin)
Karl Roscher (Neckargemünd)
Rolf Schreiber (Stuttgart)

They will receive a book price.

Very close to perfect solutions were sent by P. Maier, Sandau, Juel,
Heimerdinger, Baier, Eilenberger, Guballa, Empacher, B. Schuh and
Bergmann.

Surprisingly problem A separated the wheat from the chaff, especially
the well hidden knight on h6. Some senders solved the problems with
f7:Xe8=B, but that retraction is illegal. Others saw this illegal move,
but they did not recognize that uncapturing a white knight on h6 is
legal.

Number of correct solutions:
A: 16
B: 34
D: 17
E: 22

A: Two solutions.
a) 1.Ke3:Pd3+ e4:d3+ e.p. 2.d2-d4 b6-b5+
b) 1.f5:g6+ e.p. g7-g5 2.f4-f5+ Kg6:Nh6+!

B: Back: 1.g2:Pf3! And instead 1. R:b7 and 2. Rb8#
wBa2 is a promotee, the pawn promoted either via d7 or f7, thus
castling is not allowed for black.

D: Wolfgang Dittmann, feenschach 1877, 1st price. Judge: Stuttgart's
retro legend Josef Haas

White retracts 1.g5:f6 e.p.! and now all four knights on the board are
promotees.

E: Günther Weeth, version Nikita Plaksin, Die Schwalbe 1978, 1st price

In short: a white knight must go to c3 to shield the black king from a
bishoph's check. A white rook is uncaptured and must cross the critical
square c1. Only then the wB can go to c1 and d2-d3 can be retracted.

For a full solution please refer to the web site mentioned above. In
case you need an extended English translation, please let me know.

Best regards,
Jens
