Your games already know where you’re losing rating.
Most players train whatever is in front of them. Mated reads your last thousand games, scores you across five categories, and hands you the fifteen minutes that will actually move your rating.
You played 5…Ng4 here three times this month. d4 comes with tempo and the knight has nowhere to go.
Three steps, about fifteen minutes

- BlundersB+
One blunder every 43 moves. Better than your rating.
- DisciplineD
61% of moves in under two seconds, and they are your worst.
- TacticsC+
You see the fork. You keep missing the deflection.
- ConversionD
Nine won endgames drawn in thirty days.
- PreparationD+
Out of book on move 9 in 68% of your games as black.

Start with conversion. It is worth more than the other four put together in your case, and it is the one you can fix without learning a single new opening.

Or play a game and get taken apart, out loud.
Every move you make, picked apart by something that does not like you and does not want to help. It writes a fresh line for each mistake and then reads it to you, in a voice, while you are still deciding what to do about it.
- Two settings. It stops being polite at the second one.
- Two voices, and it actually speaks.
- It knows what you just played and why it was bad.
Part of Supercoach.
If you think that was worth it you need to reevaluate your existence.
- “Damn bro, you suck at this. Genuinely, properly bad.”
- “That move is going in the group chat.”
