Every line here is something that reached the site on the date given. Work
that changed nothing for a reader, such as tests and tooling, is left out;
the repository's own history has it. A month with no entry is a month in
which nothing a reader would notice changed.
October 2026
- 22 October
- A finished review of your own games is now counted too: which site, and how many games were read. Never the username. The privacy page lists it.
- 22 October
- The review of your own games is offered from the first visit: the start screen names it, with the two sites it reads from, and the front page says in its first screen that a Lichess or Chess.com username is all it takes. Before this it was offered only to a reader who had already cleared something.
- 21 October
- Page views and six named moments are now counted, so the maker can see whether the site is used. No cookie, no identifier that outlives the tab, nothing from a game or an account, and nothing at all from a browser that sends Do Not Track. The privacy page names the service and what it receives; before this it said there was no analytics, and there was none.
- 21 October
- The start screen has two buttons that say what they sell and what it costs: the full course and the book. Each shows only to a reader who does not own it.
- 21 October
- Your record belongs to your account, not to the browser. Signing in on a shared browser no longer adopts whatever record was already there: if the browser holds a record nobody has claimed, you are asked whether it is yours, and signing out leaves the browser as it was before you signed in.
- 21 October
- Payments went live. The course and the book can be bought with a real card, and a refund takes back what it paid for, both proven with a purchase and its refund the same day.
- 21 October
- Structure drills no longer show a board on which the game is already over. Forty-one of the 9,641 stored positions were final checkmates, found by a sweep of every stored position in the app, which turned up nothing else.
- 20 October
- On the placement paper, while a move is held on the board, the line above it says whose move it is now and asks you to confirm or take it back, instead of repeating the line from before the move.
- 20 October
- The book can be bought on its own, for $29, from the unlock page. The course still includes it. Buying the book alone gives no credit towards the course later, and the terms say so.
- 20 October
- You can change your password on the progress page. A forgotten password is reset by hand: the sign-in card has a link that opens an email to the maker, and the reset ends every signed-in session.
- 20 October
- The stored positions are now checked every month against the live tablebase and the engine: fifty tablebase starts and twenty engine-graded drills, drawn by the month. The first record, for October, found no disagreement.
- 20 October
- On a phone, the start screen's offer of twenty placement positions no longer draws a line through the words beneath it.
- 19 October
- The front page opens on a reader's file at Step IX, shot from the app itself, rather than on the mark. The mark is a letterhead stamp now.
- 19 October
- The start screen's background sound stops in a tab you are not looking at, and comes back when you return.
- 19 October
- After the ending of the day there is one choice to make, once a day, and the coach has lines for several moments that were silent before.
- 19 October
- The lessons were re-read for the voice. Several hundred dashes that were doing the work of a comma or a full stop are gone, and the sentences say the same things.
- 19 October
- The book's "In the app" lines, which point from a chapter to the node that drills it, are now written by the app from its own curriculum, so they cannot drift from it.
- 18 October
- While the coach reads his letter on the start screen there is a board on the desk, and you can move the pieces on it.
- 16 October
- The games the course sent you to play appear in your file, and every page of the file carries its date.
- 2 October
- A click drill explains the board in front of you when you are wrong, not the question it asked.
September 2026
- 26 September
- The coach says the gate-miss line on every real gate miss. The why-card names what a sacrifice gets back, counted to the end of the line, not only what it gives up. The fork drills were re-measured so that every position in them really is a fork.
- 22 September
- What comes next is said in one place and in one voice: clearing a node holds, with the next node named, instead of moving you on; the start screen has one button; the ladder shows which rungs are part of the paid course; the re-test shows its count.
- 21 September
- The seller's name and address are on the legal page and the buy page. The figures quoted in five lessons were traced to published scripts, and three of them were corrected.
- 18 September
- Weak-square and outpost drills were built. Five ideas the measurements could not support as drills are taught as quizzes and say so. Kozlov names the target he was hunting after a match. The portraits are described as generated and the voices as synthesised, on the landing page.
- 3 September
- The coach explains why a move was wrong and offers a replay. A placement paper of twenty positions can start a reader as far as Step IV. The file gets a weekly page. Your own games appear with boards and can be drilled. The ending of the day, free to everyone, is on the start screen. Coordinates come off the board after Step I. One drawn piece set on every board.
- 1 September
- Every one of the 270 nodes is built. All four characters have portraits, and every coach line that is declared is recorded.
