For the experts three more puzzles follow. If necessary a retro analysis has to be given. All sender of correct solutions will be mentioned in the review, and they will receive a book price.

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.
