[Retros] Christmas Contest of Stuttgarter Zeitung

[Jens Guballa]

Hi,

in the yesterday's issue of the "Stuttgarter Zeitung" the traditional
Christmas Contest 2006 of Harald Keilhack's chess column was published.

The original version (in German) can be found here:

Here is my translation:

<translation ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~>

As every year the readers of the "Stuttgarter Zeitung" are invited to
the contest. Among the senders of correct solutions for the problems A
and B the following prices are drawn by lot: a cordless telephone, a
microwave grill and a color TV.

Take care that after a retraction, the removal of a piece or after the
exchange of pieces a legal position occurs. And take care which side has
the move respectively may have the move! For studies and direct mate
problems always white has the move. Exception: the opposite can be
proven. In this case also black may possibly checkmate in retro
problems.

In addition you may check whether more than one solution exists.

Have fun solving!

[8/8/8/8/8/8/NPPPP3/rkBK4]
Remove a piece. Then checkmate in one move.


And here are three more problems for our experts. For D it is sufficient
to give a relatively short main variant, the computer will possibly
distract from the solution. For E a retro analysis must be given.

All senders of correct solutions for the problems C through E will be
mentioned when the solution is published, and they will receive a book
price.

[8/8/8/8/4P2p/6kP/8/4K2n]
Black retracts his last move. Then helpmate in two moves - it is black
to move and he helps to be checkmated.

[1k6/ppN5/6p1/6pp/4p3/2p1P1bP/2P1r1P1/1Q4K1]
There is the thread to loose the queen and black is up a lot of pawns.
Is there any hope for white who has the move?

Two pieces are exchanging their places. Then ceckmate in two moves.
