An essential tool for ambitious players
The recently launched Opening Encyclopaedia 2026 is an indispensable, comprehensive reference for modern opening theory. It brings together articles, annotated games and video material in a single environment, which allows the ambitious player to approach opening study in a structured way. Whether building a repertoire from the ground up or refining existing lines, the emphasis remains on understanding plans and typical positions rather than memorising moves.
The material is organised by opening name and ECO code, which makes it a straightforward task to locate specific systems or explore unfamiliar territory. With more than 1,500 articles and an extensive database of related games, each topic is supported by illustrative examples and clear explanations. Introductory tutorials provide concise guidance across the main openings, while more detailed articles assess particular variations and their practical relevance.
A range of leading authors contribute to the content, including Daniel King and Dorian Rogozenco, whose videos focus on ideas, plans and current trends. Rogozenco's series on recent developments covers major openings from 2025 into early 2026. In addition, it is possible to access searchable game collections, annotated highlights and a web-based version, which allows for flexible study across different devices.
