The new navigation
Chessou has been rebuilt around four sections, so a few things have moved. There's also a new analysis board, a newer engine, and reports that keep coming.
Navigation got a full rework
- "Home" is your day, "Games" is for playing, reviewing and analysing, "Practice" is your training.
- The two puzzle types are now called "Your Best Move" and "Their Best Move", so you know which side of the board you're working on before you start.
Your reports keep coming
- Reports stopped coming after the second one. That was a bug, it's fixed, and new ones show up again as you keep playing.
There's a new analysis board
- You'll find it under "Games". It starts from the opening position, you play out any line you want, and the engine follows along with its lines and an eval bar.
- Free for everyone, no subscription.
A newer engine runs in your browser
- It's Stockfish 18 now, so anything you analyse yourself gets a much stronger second opinion.
Puzzles judge your moves more fairly
- Any mate counts, not just the one we stored, and that holds even if you branch off halfway through.
- Sacrifice puzzles run to the point now instead of ending right after the sacrifice.
- Only your own pieces can be picked up, and an illegal move bounces off the board instead of counting as a wrong answer.
- XP follows how hard the puzzle is, and getting part of a longer one right earns points too.
Smaller things you asked for
- A "High Contrast" board in your appearance settings.
- Reporting a bug earns you 10 XP, and another 50 XP once it's fixed.
- Around 45 fixes on top, a lot of them straight from your reports.
Most of the work now goes into the repertoire builder. That's the next big one.
