Frequently Asked Questions

Chess Doctrine is a free chess learning site written by Anton Shuravin. It combines opening articles, chess terms and blog lessons with practice trainers, puzzles, chess tools and several ways to play chess.

Yes. All articles, trainers, puzzles, play pages and chess tools are free to use, and you do not need an account.

The opening articles explain the ideas, move orders and typical positions. The opening trainers turn those lines into Learn, Drill and Play sessions, so you can practice recalling and playing the moves.

The Practice hub links to opening, endgame, strategy, positional judgment, calculation, blindfold and board-vision training. Each trainer explains its own task before you answer.

The Chess Tools hub includes the Chess Analysis Board, Chess Board Editor, Chess Next Move Checker, Elo Calculator, PGN Filter and Mega Chess Analysis. Each tool has a short guide on its page.

Mega Chess Analysis reviews a set of your games, finds mistakes that repeat and connects the findings to relevant drills, trainers or puzzle sets. You can paste PGN or fetch games by username where the page offers that option.

Each board tool describes on its own page how it processes and stores data. For data handling across the whole site, see the Privacy page.

The Play Chess hub offers play against a computer, a human-like training bot and chess-legend opponents. Open the mode you want and follow the setup shown on that page.

The Chess Legends hub has 34 historical players, including Paul Morphy, José Capablanca, Mikhail Tal and Bobby Fischer. Each legend page explains the opponent and lets you choose how to begin the game.
