As every year the StZ-readers are invited to the contest. Among the senders with the correct solutions of problem A and B the following prices are drawn by lot: a Philips-television, a DVD-player and a digital camera.

Please pay attention to receive a LEGAL position after the retraction of a move or after the insertion of a piece. Additionally check, which side has the move (respectively can have the move). Also please check whether more than one solution exists.

From a position with four pieces it can be shown that on exactly three light squares no white bishop ever occurred. How many of those positions exists where EXACTLY THREE PIECES - including both kings - are positioned on squares of the same color? E.g.:

[8/8/8/8/8/8/2P1P3/1K3k2]

Here the white bishop never occurred on the squares c2, d1, e2. But this is not a solution as ALL FOUR pieces are positioned on squares of the same color!

White retracts three, black
retracts two moves. Then white checkmates in

two moves. Defensive Retractor, i.e. black does not cooperate during
the

retraction, so he has a choice.
