Our Canadian member Ken MacDonald is a marked specialist in the literature and the history of correspondence chess – and he’s in very good company as Eric Ruch and Tim Harding are experts in this field too. Ken published some surveys on North American CC tournaments and – in a small number of copies – a booklet on the Canadian GM Daniel Abraham Yanovsky (10 copies only!).
In 2006 he presented together with Leonard Zehr his most extensive work, a history of Canadian correspondence chess, the trail of which he had picked up 30 years before in Cleveland.
