Why am I getting worse at chess? Check these five causes in your own games

Ratings move around. Judge a drop over weeks in one time control, not over an evening. New and inactive accounts swing more because the rating deviation is high, which Chess.com explains and the Lichess FAQ describes for its own system. A number that falls can still be a habit, not a loss of skill. What "good" means is in what is a good chess rating.

Symptom: you score worse in games you start soon after a loss, and losing streaks get long. The fingerprint compares that score with your other games. The window is approximate. It is not a perfect detector of every emotional rematch, so read it as games started soon after a loss, not as a clinical test.

Fix: decide a stop rule before you play. How to stop tilting is the full version. In short, review the loss for a couple of minutes before you queue, and stop the session after the rule you wrote down, often two losses in a row.

Symptom you can notice yourself: the last games of a session are faster and looser than the first. RookMentor does not compute per-session fatigue, so a fingerprint cannot prove you were tired. You can still cap the session. When the games get sloppy, the session is over even if the stop rule has not fired.

A simple session cap

1. Before you start, write how many games you will play.
2. After each loss, stand up before you press rematch.
3. If you cannot say what the opponent's last move threatened, stop for the day.

Symptom: more bullet or blitz, more moves under 5 seconds after move 10, more losses on time. The clock readings are in time management. Whether fast games are your training diet is in blitz or rapid. The fix is not "never play blitz." It is to put reviewed, slower games back in the week if improvement is the goal.

GM Noël Studer writes that breaking a plateau means being willing to get worse in the short term. He tells improvers to commit to something new for a period, usually one to three months, and gives a concrete opening example: play a new opening for at least one month before you compare results. In the same article he says online players may lose 50 to 100 points while they learn, then gain the points back by returning to old habits and skipping the improvement. That range is his coaching observation, not a RookMentor measurement.

If you started a new opening or a new thinking habit in the weeks before the drop, the drop can be the dip he describes. Finish the period you committed to, then judge. Do not abandon the idea on the first bad night.

Symptom: one opening's score falls, or one phase keeps going wrong. The way to count that is how to find your weaknesses. Opening choice is in which openings to learn. A single bad result is not a collapsed opening. A low score over enough games is.

1. Look at rating history for the time control you play most. Note when the drop started.
2. Ask what changed that week: faster time controls, a new opening, longer sessions.
3. Split losses by how they ended: on time, checkmated, or resigned.
4. Compare games you started soon after a loss with the rest. Note your longest losing streak.
5. List openings where the score is clearly worse than the others.
6. Pick one cause. Work on that before you add a second fix.

A few games can swing a rating, especially when the deviation is high. If the checklist above is quiet, the history is a wiggle, not a new weakness. Play the next games under your stop rule and review one of them. How to get better at chess is the longer method. The 1000 band is one place those habits show up, not a diagnosis of your account.

Common mistakes

• Deleting an opening after three losses. That sample cannot show a pattern.
• Playing faster to "win the rating back" the same night.
• Treating a fingerprint tilt gap as proof of a character flaw. It is a score comparison in games started soon after a loss.
• Expecting a tool to measure how tired you were. It cannot.
