I held a talk at the club yesterday. For everyone to enjoy the material, I added it to the site. Well, at least to my download/ownCloud server. You may need to adjust the paths to videos and games for the presentation to work as intended. You may need LibreOffice or an Office-suite that can handle LibreOffice files. You also need a chessbase program that can handle scid-files (generally Scid). Also, a general knowledge of chess is helpful.
David Bronstein played a match against Mikhail Botvinnik for the title of world champion, which ended undecided at 12-12. According to the rules of the day (1951) this meant that Botvinnik retained his title. Bronstein also played in the candidates tournaments of 1953 and 1956, but never again played for the world champion title.
