Max Friedrich William Bezzel (1824 – 1871) was a German chess composer who created the eight queens puzzle in 1848.

Rearrange the eight queens so that no two of them attack each other. For an extra challenge, make sure that no three of them lie on a straight line.

The original puzzle has 10 unique solutions, up to rotation and symmetry. With the additional restriction imposed, there is only one solution.
