Build the player, not just the rating.
ChessPillar is a personal chess improvement and preparation workspace for ambitious adult players. It exists because more material was never the missing piece. Knowing what to work on next, and knowing that it worked, was.
More puzzles are not a plan.
A puzzle tells you a tactic is there before you look. Your games never do. Seeing one at move 19 is a habit, and habits are built in order, under resistance, and again once you have half forgotten them.
So ChessPillar is a curriculum with a plan on top. A skill is not yours until you have shown it in separate ways: recognising it, calculating it, applying it, holding it in a Fight, remembering it weeks later and finding it in your own games. Every attempt is stored as it happened, so the claim can always be recomputed. How each part of the plan works
Select every white piece that attacks d5.
Progress is evidence
ChessPillar tracks each skill across six kinds of evidence, each on its own: recognition, calculation, application, Fight, retention and real games. You can see which one is missing. A skill counts as mastered only once it passed its review after 16 days.
Hours and streaks measure engagement. They are not proof that you got better, and ChessPillar does not present them that way.
Who decides what is right
Nothing is published on the strength of an opinion, including ours. Code and engines own chess correctness. People decide what is worth teaching.
- Rules code
- Validates every position and every move before anything else looks at it.
- Stockfish
- Verifies every accepted answer and every Fight goal. An answer fails only if it gives up the position, never for being second best. All 2,118 positions in the course carry a Stockfish verification stamp.
- Endgame tablebases
- Where a theoretical endgame is small enough to be solved, the answer is looked up. 135 positions carry an exact tablebase probe.
- Three kinds of review, kept apart
- Engine checked, editor reviewed and expert reviewed are separate records. ChessPillar does not call a lesson expert reviewed unless a review of that lesson is on record.
- Research, then original work
- A Level begins with a pass across independent sources, including prose instruction where it exists, and ends in an original lesson with original exercises. Research shapes how a Level is taught. It does not decide what is correct.
- Language models, only to explain
- No language model decides whether an answer is right, what you have mastered, what to train next or what you are charged. Where an explanation is written by a language model, it is written only when you ask, and only the position, the moves and the engine’s own readings are sent. Nothing you type, and no email address, reaches a model.

- Miss a week and nothing resets, empties or turns red. Your reviews wait until you are back.
- Sell you a currency.
- No gems, no hearts, no hints for sale.
