I always wondered if anyone had made the effort to include chess terms within the structure of Esperanto. As the language used European languages as the basis of its nouns I thought it was likely, although I had not come across any results. But leafing through a Edward Winter book on Otley library yesterday, I saw an article just on this topic.
Fortunately Winter has a lot of his content online, as well as in print form, and I was able to track down his webpage covering this. It is at http://www.chesshistory.com/winter/extra/esperanto.html and although it mainly features references to columns and books in the early part of the 20th century, still makes an interesting read,
