Arrange all sixteen white pieces and the black king on a standard 8x8 chessboard such that no piece is in check by another piece.
The arrangement must be possible to reach following rules of standard play (though such play would be ludicrous),
with no pawn having reached the eighth row for promotion.
(In reply to a computer solution
In the manually transformed solution:
. . n . * . . k
. . p . . . . .
b . n . p p . p
. . b . . . . .
p . p . . p . p
. . . . . . r .
. . . r . . . .
. q . . . . . .
the bishop that had been in the rightmost file and is now in the leftmost file, now attacks a pawn and a knight, so this is not a viable alternative to the computer-found solution.
