England was kingless (and queenless, for that matter) for a few brief periods in a history of otherwise unbroken monarchy. One of those times was during the rule of Oliver Cromwell, who took the title of Protector.
Bill Salot has given a new meaning to "kingless" in his latest checker problem composition contest, in which all problems are to consist of single men only; no kings are allowed. We doubt that Mr. Salot has ambitions to be another Cromwell; his fame as a promoter of modern-day problem composition is already assured.
