Know what to do while they're still thinking
The moves come from practice, not recall. You play the opening at speed and keep your clock for the part of the game that decides it.
Know exactly what to play out of the opening.
Pick a repertoire, drill the critical lines on a real board, and arrive at your next game with a plan instead of a guess — a position you understand coming out of the opening, and a gambit your opponent has never had to answer.

Come out of the opening better off
Not a list of moves — a position you understand, with a plan for what comes next and the ideas behind it.
Spring the gambit they've never faced
Learn the sharp lines properly: the trap, the refutation, and exactly what to play when they find the only move.
Our Philosophy
Everything you need. Nothing you don't.
"Pick the opening. Learn the critical lines. Drill them on the board. Sharpen your board vision. Track what sticks. One tool instead of five."
Getting started
1. Choose your repertoire
Pick an opening that fits how you play. Choose the lines you want in your games.
2. Learn only what matters
Courses cover the critical moves, ideas, and continuations. Nothing else.
3. Train until it sticks
Drill lines on the board. Hammer the moves you keep missing.

Can I try it for free?
Yes. The full opening explorer and the first lines of every course are open to everyone, no account needed. Create a free account to save your progress and step through each course on the board. A 14-day trial or a subscription unlocks the full courses and the drills.
What is not included in the free preview?
The free preview is the first lines of each course plus read-only drill boards you can click through. The rest of each course, the coordinate and memory drills, and training built from your own games need a trial or a subscription.
What happens during the free trial?
Everything unlocks for 14 days. Full opening courses, board rehearsal, unlimited coordinate and memory drills, Stockfish evaluation, and progress tracking, so you judge the whole product before you pay.
What happens when my trial ends?
Nothing is deleted. You drop back to the free preview and keep the first lines of every course, along with your progress. Subscribe whenever you want the rest back.
What is included with my subscription?
Every opening course, unlimited board training, the opening explorer, unlimited coordinate and memory drills, Stockfish in your browser, training from your own games, progress analytics, completion badges, and every future course.
How is Chesstrophy different from Lichess, Chessable, or PGN files?
One goal: a repertoire you remember and use. Courses, exploration, board drills, engine feedback, and progress live in one workflow instead of five tools.
What is the Founding Supporter badge?
Subscribe during the founding window and the badge lands on your profile permanently. It marks you as an early member, and early members get first access to what we ship next.
Who is Chesstrophy for?
Any level. If you study openings and forget them in real games, this is for you.
Can I cancel at any time?
Yes. Cancel anytime and keep access until your current billing period ends.
