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.
