“I was sure tactics were my main problem. The report showed I was already getting into trouble in the opening. I changed what I studied and my games started to feel much easier.”

“Comparing my play with others around my rating was the part I liked most. It helped me spot the same mistakes coming back in different games, rather than just giving me a list of bad moves.”
Marcus V. · 2078 blitz
“I check my games straight after playing now. It takes me to the important moments quickly, so reviewing a session no longer feels like another hour of work.”
Sophie R. · 1437 rapid
“What helps me is seeing when a mistake is part of a bigger pattern. A single blunder does not tell me much, but noticing the same problem across a week of games does.”
Liam T. · 1886 blitz
“The exercises actually relate to positions I play. I can work on my openings, go back to positions I handled badly and practise exactly what came up in my report.”
Elena M. · 1742 classical
“I never have to wonder what to train next. There is enough variety to keep it interesting, but every session still feels connected to the things I need to improve.”
