It doesn’t take a chess wiz to figure out how to dress up like Beth Harmon this Halloween. In 2012, the United Kingdom, Indonesia and Russia entered competitively at WCS, with Hong Kong and Taiwan participating under observer status, bringing the total number of represented countries to 22. WCS expanded to 12 days for its 10th anniversary, with official visits paid to Gifu, Mie, Tottori and Aichi Prefectural offices, and a second parade was held in Ichinomiya during the Tanabata Festival.
