the 1950s it has settled in at eight per issue). The answers to each question are given in the next issue, along with comments by expert panelists and by the panel's moderator. This arrangement provides a means for the reader to improve his bidding skills, and to get a glimpse of the thought processes of the experts. Readers (or, in the context of the MSC, "solvers") are invited to submit their monthly scores to TBW. An annual competition is held for the highest 12-month total; the winner is invited to participate on the expert panel for a year. For many years, the MSC was conducted by the same person each month: Samuel Fry Jr. from 1932 through 1945 and Albert H. Morehead from 1945 until his death in 1966. In January 1967, when Kaplan and Rubens took over TBW's editorship, a rotating group of directors was established: Moyse, Alfred Sheinwold, Howard Schenken, and Alan Truscott each directed the Club once every four months. Retirements, editorial disagreements, and health problems led to changes in the Club's directorship, and well known players such as Bobby Wolff, Jeff Rubens, Eric Kokish, Kit Woolsey, David Berkowitz, Larry Cohen, Bart Bramley, Danny Kleinman, Steve Landen, Karen McCallum, and Barry Rigal have all served as directors. In 2005, the MSC changed from a rotation of four directors to a rotation of six. The form of the MSC has also changed markedly over the years. It was originally conceived as a means by which readers could test themselves on the Culbertson System, and for years it was held that there was only one correct answer to each problem – there being only one correct answer in the context of the Culbertson System. In the 1940s a system of partial credits was instituted, with the "correct" answer receiving 100 points and lesser awards going to other answers. A related change occurred in 1951, when the answers provided by experts other than the director were printed, along with their comments. According to TBW's history of the MSC, this was the magazine's first explicit acknowledgment that such a panel existed. The inclusion of expert comments has continued ever since. Although most of the monthly problems concern bidding, under the Kaplan/Rubens editorship there has been one problem each month concerning leads, nearly always opening leads. As to the problems that concern bidding, the experts' answers and comments lost clarity as the
