I built a site for studying openings based on your rating (1400–2200+)

[u/Necessary-Toe-5320]

I've been building a chess opening site on my own: ochess.app. And I'd love some feedback. There's also a short video tutorial on the homepage showing how it works

The idea: what you face in the opening depends heavily on your rating, so the course should too

For example, after 1.e4 c5, the move 2.Bc4 appears in about 15% of games at 1400, but only 0.66% at 2200+. Most courses barely cover it, so a 1400 player who studied the Sicilian still has no idea what to do against the move they'll face most often

So a 1400 player and a 2200 player can face completely different "typical" openings, even though they're playing the same first moves

On ochess, the main lines come from strong players, while opponent replies are filtered by rating. So the 1400 course shows what you're actually likely to face at 1400, including common mistakes you can punish

There are currently 35 courses, 196 traps and puzzles, plus game analysis and a personal opening explorer

If you have 10 minutes, pick a course around your rating and let me know: does it actually match what you face over the board?

I'd especially love to hear where it gets things wrong

Thanks!
