Chess guides, written properly

The Library is every long-form chess guide on Grandmaster Gains in one place: twenty-one openings written from both sides, seven complete guides to the rest of the game, twenty variants explained and the practical guides for parents, coaches and clubs. No fluff and no filler, just the plans, the structures and the mistakes that actually decide games, all free and all playable on a live board.

Start a free game on a live board while you read; no sign-up.

Most chess content online is either a wall of variations nobody remembers or a list of principles too vague to use. These guides are written the way a coach explains an opening across a board: what the first moves are for, the handful of plans that recur in every game, the pawn structure that decides which squares exist, and the specific mistakes that lose. Every opening is covered twice, once for the player using it and once for the player facing it, because knowing how to play the French and knowing how to beat it are different skills that happen to share a name.

Everything here is free and everything here is playable. Each guide ends on a live board where you can try the structure against a real engine and have every move rated afterwards, which is the part that actually turns reading into rating points.

Complete guides

Seven guides covering everything the Academy teaches, each one the full write-up rather than a single drill.

Which chess opening should you learn?

Twenty-one openings, each written twice: once for the player using it and once for the player facing it, because those are genuinely different problems.

Everything a first-time family needs to walk into a tournament and understand what is happening.

For parents

Starting a child in chess, keeping them in it, and the questions every chess parent asks.

Improving your own game

For the adult or teen player who wants to actually get better, not just play more.

Choosing chess lessons, coaching, puzzles and variants

Paying for lessons, or not: what they cost, how to choose them, and what the free ones already cover. Start at the chess lessons hub.

Chess coaching

Before you book a coach: the price, the questions to ask, how long it takes, and when self-study wins. Start at the chess coaching hub.

Chess puzzles

Free against paid, which puzzles to solve at your level, and the habits that waste the daily set. Start at the chess puzzles hub.

Chess variants

Which variant to play, how each one works, what it costs (nothing here) and how long it takes to learn. Start at the chess variants hub.
