At the same time, the process of making chessboxing a professional discipline reached a milestone: The 2013 World Championship in Moscow was the first chessboxing event organized and marketed by Chess Boxing Global. With three world championship fights in one night, more than 1,200 spectators, and a standard of fighting never seen before, the first CBG event set new standards in the history of chessboxing, with Leonid Chernobaev leading the way. He has been able to make a name for himself with more than fifteen years of chess-playing experience, and in the boxing world as Marco Huck's and Yoan Pablo Hernández' sparring partner, and having fought over 200 amateur bouts. He won the light heavyweight title against Indian fighter Shailesh Tripathi after a technical knockout in the eighth round (boxing). Sven Rooch secured his title in the middleweight class division—winning against Jonatan Rodriguez Vega after the Spaniard resigned in the seventh round (chess), and Russian Nikolay Sazhin won the heavyweight title against Gianluca Sirci by checkmate. Thus, Sazhin (heavyweight), Chernobaev (light heavyweight), and Rooch (middleweight) would all go down in chessboxing history as the first Chess Boxing Global World Champions.
