Background

I started playing chess in my teens, stalled around the club level as most amateurs do, and spent the next decade occasionally preparing for weekend tournaments and then forgetting what I had prepared. Professionally I build software — mostly in fintech and education-adjacent products. I built ChessAtlas in 2025 to solve the preparation-then-forget cycle I kept running into, then kept going because the tool turned out to be useful to other club players too.

What I write about here

• Construction of repertoire. How to build your first repertoire, how deep to go at each rating level, how to use Lichess and Chess.com game history to figure out what to study next.
• Spaced repetition for chess. Why FSRS beats SM2 on real workloads, how chess-specific considerations (transpositions, move-order sensitivity) interact with SRS scheduling.
• Tool comparisons. Honest side-by-sides between ChessAtlas and Chessable / Lichess Studies / ChessTempo / ChessReps / Chessbook. When a competitor is better for a specific use case, I say so.
• Product tutorials. How to use the Deviation Finder, how to import PGN, how the library courses work.

Opening theory at the grandmaster level, detailed middlegame evaluation, and endgame content are outside my level of expertise. Those topics on the site come from cited sources or are explicitly flagged as outside the author’s competence. See the editorial policy for how we handle that.
