Your task is to set up a symmetrical (both vertically and horizontally) position on the first 7 ranks of a chess board that meet all of the criteria below.
For this puzzle, there is no eighth rank. It does not even exist.
That makes a chess board with 7 ranks x 8 files = 56 squares.
You have only the following pieces and must use all 52 of them:
White:
8 kings, 8 rooks, 4 bishops
Black:
20 kings, 4 rooks, 8 bishops
The pieces must be placed on the 7 x 8 chess board such that all of the following criteria are met:
- No king is in check.
- No piece has any legal moves.
- The position has horizontal and vertical symmetry (by both colors and pieces).
In other words, rearrange the pieces in the setup at this link to meet all of the criteria above. (Example image below)
Note: You don't have to use the link. You can use any other board or website, of course. The link is just one quick, easy option.
