I make this each year as an aid to myself as I study the rules. I posted mine here last year and several people seemed to appreciate it, so I figured I might as well post the one I made for this year as well.
It’s mainly focused on a refereeing perspective, so most of it is the list of infractions and penalties as well as the details of scoring. But maybe other people would find it interesting as well.
It uses a pretty small font in places in order to fit everything on one page, so if your eyesight isn’t perfect this may not be for you. (Sorry, I just find it really useful to put everything on one page.)
Feel free to adapt it and make it your own. (Actually, I recommend that people make their own cheatsheets in general.) I hereby dedicate this document to the public domain. (Well, the parts of it that aren’t cut-and-pasted from the manual, I suppose.) I am posting the original which I made in LibreOffice Writer, and a PDF version.
