This blog series covers a wide variety of topics under chess problems and compositions. Many are perhaps articles in disguise and serve as introductions to subjects such as certain themes and problem forms. Some focus on particular problemists, books, software, and so on. Occasionally I write more traditional blogs that express a personal view or consider my own compositions. To assist readers looking for specific topics of interest, the entries are grouped into various categories below.
Some blog posts here are republished on Chess.com: The Problemist's Blog.
