Our ongoing series of special Wednesday columns, intended to provide a little extra checker entertainment when we need it the most, continues with another fine and tough problem from master composer Ed Atkinson. He named it after Donnybrook Fair, which was known for its frequent brawls. If you solve this problem, you'll see why the title is appropriate.
Be forewarned; this is a doozy! Once again, you have two weeks to work on it before we publish the solution.
We hope you are enjoying this series. Stay safe and healthy, checker fans, wherever you are.
