In checkers, there are compound strokes as well. We'll let Mr. Bill Salot explain them as part of Unofficial World Championship Problem Composing Contest #59, which is now active and available on the contest page. Four tantalizing and action-packed problems by some of today's finest and most talented composers await your solving pleasure.
