Chess improvement guides

Short, practical guides to getting better at chess: finding your real weakness, analyzing your own games, and making patterns stick. For the product behind them, see the About Mainline page.

How to find your #1 chess weakness

The fastest way to find your biggest chess weakness is to analyze a batch of your own recent games with a strong engine and look for the mistake that repeats. Here's the step-by-step.

How to analyze your own chess games

To analyze your own chess games effectively, review each game once on your own first, then check it with an engine, and focus on the moments where you had a decision.

Spaced repetition for chess, explained

Spaced repetition is a learning method that re-tests material at increasing intervals so it moves into long-term memory, one of the most effective ways to make chess patterns automatic.
