This page is for players who are already putting in practice time and want to know whether more practice is the right next move, or whether the real bottleneck is that they still have not diagnosed the mistake pattern showing up in actual rated games.
That distinction matters. Practice is valuable, but practice without a clear diagnosis can reinforce noise. If you are rehearsing broadly without knowing whether your main leak is conversion, defense, planning, or time management, you are training less efficiently than you could be.
