Encyclopedia Chess Informant 1

1000 high-quality puzzles for players rated ELO 2000

Encyclopedia of Chess Combinations vol. 1 (ECC vol. 1) is the definitive educational resource, featuring systematically organized, expertly curated content tailored for players at the ELO 2000 level. This material draws from the latest edition of the bestselling book of the same name, published by Chess Informant. The volume includes Basic Level (ELO 2000) chess combinations for solving—each one hand-picked and grouped by theme to deliver the most engaging and effective training experience available. Unlike the scattered, basic tactics found across the web, this Chess Sphinx offers consistent, systematic challenges, revealing deeper layers of complexity just as you feel you've mastered a concept.

This course is part of the Chess King Learn series (https://learn.chessking.com/), an innovative chess training methodology. The series encompasses courses on tactics, strategy, openings, middlegame, and endgame, organized by skill level from beginner to advanced, and even suitable for professionals.

By using this course, you can deepen your chess understanding, acquire new tactical ideas and combinations, and apply what you’ve learned in practice.

The program functions like a personal coach—assigning puzzles and offering support when you're stuck. You’ll receive hints, clear explanations, and sometimes even striking refutations for common errors.

A theoretical section is also included, explaining key strategies for specific game phases using real examples. The theory is presented interactively: not only can you read the lesson text, but you can also make moves on the board to explore unclear ideas firsthand.
