공개로 남기고 싶은 모든 것 — 그리고 나중에 다른 사람이 찾을 수 있어야 하는 모든 것. 버그 신고 대부분이 여기에 해당합니다.
문제가 잘못되었을 때
네 가지만 보내주시면 확인은 일 분이면 끝납니다.
- 문제 화면에 표시된 FEN — 길게 눌러 복사할 수 있습니다.
- 당신이 둔 수와, 앱이 정답이라고 한 수.
- 어떤 모드였는지.
- 앱 버전. 정보 화면에 있습니다.
문제는 이따금 더 깊은 탐색과 어긋납니다. 그런 어긋남은 요점이 검증이 닿은 곳보다 더 깊이 놓인, 길고 조용하며 높은 레이팅의 국면에 쌓입니다. 그것은 검증의 한계이지 문제의 오류가 아닙니다 — 다만 어떤 것들이 그런지 아는 편이 낫고, 아는 유일한 방법은 당신이 알려주는 것입니다.
질문
적어둘 만큼 자주 나오는 것들.
- 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.
