Bulletin of the Chess and Checkers Tournament for the Championship of the Central Committee of the Union of MTS Workers of the South and Center. Kharkiv, April 5–12, 1935.
Kharkiv: Ukrainskyi Robitnyk, 1935.
72 pp.: ill. Illustrated softcover, small format (150 × 110 mm). Print run: 3,000 copies. Editor: I. Tseytin; Technical Editor: N. Tsirulnitsky; Proofreader: Ya. Sklarsky.

This 1935 bulletin is a rare and fascinating artifact of Soviet sports history, specifically documenting the intersection of intellectual games and the massive industrialization of the countryside. Published in Kharkiv (then a major administrative and industrial hub), the booklet records the championship for workers of the Machine and Tractor Stations (MTS)—the backbone of the Soviet agricultural system during the mid-1930s.
The bulletin contains a detailed record of the chess and checkers (shashki) competitions held over seven days in April. It includes tournament tables, selected annotated games, and tactical problems. Such publications were vital for the "Chess in the Masses" movement, aiming to elevate the cultural and intellectual level of the proletariat and rural workers. The text reflects the competitive spirit of the MTS workers of the South and Central regions, showcasing the grassroots popularity of these games outside of Moscow and Leningrad.
Beyond the moves on the boards, the bulletin serves as a sociological document. It captures the language and ideological atmosphere of the Second Five-Year Plan, emphasizing the "cultural growth" of the rural working class. The pocket-sized format was intentionally designed so that workers could easily carry it and study the games during their breaks at the stations.
With a small regional print run of 3,000 copies and its nature as a "throwaway" ephemeral sports publication, very few copies have survived to the present day. It is an exceptional find for collectors of chess memorabilia, historians of the Soviet 1930s, and those interested in the history of Ukrainian publishing and sports organizations.
