Originally posted by ilywrinNotice that in the starting position black is in zugzwang. A king move results in mate (1. ... Ka8 2. Ka6 and 3. b7#, 1. ... Kc8 also results in checkmate however it is longer). The knight is also stuck defending the f3 pawn.
In that case I guess the first move is 1.Bb1.
Though it is obvious White's king should descend to a1, then the bishop should return to a2 and the king procceds through the first rank I am missing the strategical concept behind it. May it ...[text shortened]... at c2 with the king allowing for Bb1-Ba2 type of "empty" moves?

In which case the position is illegal.

Seems legal to me.
White makes 7 P captures - Black is missing 7 units.

White played fxe, then promoted on e8 to obtain the third Bishop.
Black promoted his a-pawn after White played axb. In this manner, the missing a-pawn becomes useful for sacrifice.
