公開のままにしておきたいことすべてに——そして、あとから他の人が見つけられる必要があることすべてに。バグ報告のほとんどはこちらに当てはまります。
問題が間違っているとき
四つ送っていただければ、確認は一分で済みます。
- 問題画面に表示されている FEN——長押しでコピーできます。
- あなたが指した手と、アプリが正解と呼んだ手。
- どのモードだったか。
- アプリのバージョン。情報画面に出ています。
問題はときおり、より深い探索と食い違います。その食い違いは、要点が検証の届いた先より深いところにある、長く静かで高レーティングの局面に集まります。それは検証の限界であって問題の誤りではありません——ただし、どれがそうなのかを知っておく価値はあり、それを知る唯一の方法はあなたが教えてくれることです。
質問
書き留めておくくらいには繰り返し聞かれること。
- Does it need an internet connection?
- No. The engine, the puzzles and your progress are all on the device. The single exception is online play, which needs Game Center to reach the other person.
- Is there an account?
- There is none to create. Your ratings and history live in the app’s own container on your device, and deleting the app deletes them.
- What is free?
- Playing is free and stays free — against the engine, against a person over Game Center, and the nine hundred games in Watch — all unlimited. On top of that a free account gets five a day of each kind of training: five tactics puzzles, five Rush runs, five positional exercises, five endgame drills and five games to judge. The allowance resets at nine in the morning, local time.
- Why is there no advertising?
- Partly taste and partly licence. The app links two engines — Stockfish under the GPLv3 and Reckless under the AGPLv3 — and compiling a proprietary advertising SDK into the same binary would make the combined work undistributable under either. Selling the app is fine; copyleft has never forbidden charging. Bolting a closed SDK onto it is not.
- Are my puzzle ratings the same as a FIDE rating?
- No, and they run several hundred points higher. They measure progress against yourself, not strength against a field.
- Where do the puzzles come from?
- Most are from the Lichess puzzle database, released into the public domain under CC0, carrying ratings calibrated against millions of real solving attempts. The rest were mined locally by having Stockfish play itself and keeping only positions where one move is far better than every alternative.
- Can I see the source code?
- Yes. The app carries the GNU Affero General Public License version 3 — the terms Reckless brings with it, which the GPLv3 of Stockfish permits combining with — and the complete corresponding source is published on GitHub.
- Which engine am I playing?
- Whichever you chose in Settings. Stockfish and Reckless are both compiled into the app, and one of them plays, grades and labels everything. They are not equivalent: Stockfish can be asked to play anywhere from about 1400 to full strength, while Reckless has no strength limiter and plays at full strength or not at all.
