## Introducing the Art of Chess Composition

### by Peter Wong

This series of articles aims to introduce the field of chess problems to solvers and players, covering its many aspects, and assumes no prior knowledge of the subject. All special terms are explained and for easy reference, the most important ones are linked to their definitions on the Glossary page. Each article contains six high-quality problems (by composers from around the world) that illustrate the topic under discussion, all with their solutions clearly analysed.

*Note that these articles, and indeed this whole site, follow a chess problem convention in using ‘S’ to represent the knight (from the German word, *Springer*). ‘N’ is reserved for a fairy piece called the nightrider.*
