About personalchess.club
Your own Chess.com games, reviewed move by move: where each game turned, the better moves you missed, and the habits that come back from game to game.
How a game is analysed
Every move of every game is checked by a chess engine on our servers. A move's grade comes from how much of its side's chance of winning it gave away, from 0 to 100 points, compared with the engine's best move. The moments that decided a game are searched again, deeper, with the engine's three best lines. The game page names the engine and the depth of what it shows.
- Best. The engine's own first choice.
- Excellent. Not the first choice, but it kept almost all of the winning chance (under 2 points lost).
- Good. A sound move that lost a little of the winning chance (under 10 points).
- Inaccuracy. Gave away 10 to 20 points of the winning chance.
- Mistake. Gave away 20 to 30 points.
- Blunder. Gave away 30 points or more.
- Missed checkmate. A checkmate in three moves or fewer was there and was not played.
