Know what to do next.

Chess gives you more than enough to study. RBOTChess helps you decide what matters next.

Build a Development Plan, train one opening with Coffee Break, or work directly in the tools.

What it does

Every recommendation states its reason.

RBOTChess does not hand you a list of things you could do. It names one next step, and it says why that one — from your plan's current stage, the work already logged against it, and the openings you actually play.

If the reason is thin, it says that too. A recommendation you cannot check is not guidance.

Example

Your next step

Review one of your recent London System games with Silman analysis.

Why this now: No analysis logged toward this planning indicator yet.

Counts toward: “Maintains a critical-moment log for at least 15 analysed games.”

Each move must have a purpose.
A training session should be no different.

Most players do not lack information. They have openings, engines, databases, puzzles and videos. The harder problem is deciding what deserves attention now.

Competence is knowing what the position requires.

What it is built on

Opening preparation built from what players at your level actually play.

Generic opening books show you what grandmasters play. RBOTChess is built from millions of real games filtered by rating band, with one prepared response for each relevant position — engine-verified, and chosen against the moves players at your rating actually choose.

That same preparation is what the three modes work on: it is the tree the Opening Tree reads, the material Coffee Break sequences, and the opening work your Development Plan schedules.

14 million Lichess games

Your exact rating band. Real opponents. What they actually play.

One prepared response

For each relevant position. Engine-verified and level-adapted.

93–99% coverage

Verified against the moves your opponents will actually make.
