不積跬步,無以至千里

Without accumulating half-steps,
there is no reaching a thousand li.

Most chess advice is either folklore repeated until it sounded true, or motivation dressed up as method. This is neither. It is a complete training path built from published research and primary texts — and it is honest about how long this takes, which is the part everyone else leaves out.

~26%
Of the variance in games skill that practice actually explains, per a meta-analysis of 157 effect sizes. The other three quarters is not yours to control.
1,000+
Documented cases of rated players gaining 200+ points after age 25. Adults do improve. The ceiling is lower than the internet implies and the timeline is longer.
41
Median age at which rated players hit their peak rating. If you are in your thirties or forties, you are not late.

Start here

Two inputs — your rating and your honest weekly hours — produce your training week, your current rung, and a realistic timeline. Everything else on this site is the reasoning behind that output.

Build your plan

The generator uses base rates from the best available dataset on amateur improvement, scaled to your available time. It will tell you things you may not want to hear — including, at low weekly hours, that 2000 is probably not reachable.

What makes this different

It says when the evidence is thin

Everyone tells you to play longer time controls. We do too — but no study has ever compared improvement rates across time controls at matched effort. That is strong coach consensus with a plausible mechanism, not a demonstrated fact, and this site says so at the point of advice rather than burying it.

It names the folklore

The famous 40-40-20 rule has no identifiable originating source and omits game analysis entirely — the one activity multiple datasets single out as the top predictor at novice level. And there is no credible figure for "% of beginner games decided by a hanging piece." Any such number you have seen was invented.

The method has two independent lineages

Seven principles, each pairing a verified passage from the Analects, the Doctrine of the Mean or Xunzi with the modern research finding that arrived at the same place two and a half thousand years later. Confucius withholding instruction until the student has struggled is the testing effect, stated in 500 BC.

Every position is on a board

Forty-four diagrams, and every notation line on the site is steppable — walk the moves one at a time and watch the position change, on the page, with no account and nothing to install. The boards are generated from verified FENs at build time, so the diagram you see here and the one printed in the book are produced by the same code and cannot drift apart.

The chess is checked

Every move sequence in the repertoire has been replayed through an engine for legality and cross-checked against published theory. Four errors were caught that way — including a line containing an illegal move. Where a line is playable but not main theory, it says so on the spot.

The uncomfortable arithmetic

This is the part that belongs on the front page rather than hidden three clicks in.

The best dataset on adult improvement (n≈384 self-tracked players, median 7 hours a week) gives expected annual gains by band: +215 from 800–1099, +121 from 1100–1699, and +37 from 1700–1999. Integrate those and 800 → 1800 is roughly a nine-year project at seven hours a week. 800 → 2000 is closer to fourteen.

Independent cross-checks land in the same place. One documented improver went 981 → 2000 USCF in 14 years. Another went 1474 → 2007 in 10.5 years — with only four productive years out of eleven. The fastest well-documented 800 → 1800 took 3 years 2 months and required 10–30 hours a week and around 30,000 games. That is a near-professional load, not a hobby.

And in that same dataset, the 25th percentile of players rated 1200 studying eight hours a week gained exactly zero across a year. A flat year is normal. It is not evidence that you are doing something wrong.

Why that is not a reason to stop

The same screening that produced those timelines also found over a thousand adults who gained 200+ points after 25, and around two hundred who gained 500+. The single factor its author named first was consistent play — "more important than studying, coaching, chess psychology, or anything else." What the data rules out is the fantasy of a fast leap. What it supports is a long, unglamorous accumulation. Which is exactly the thing Xunzi was writing about.

If you read only one thing

Read Principle Ⅱ — analyse your games with the engine off first, before you look at anything. Write down what you were thinking at the moment it turned, from memory, then commit to a better move, and only then turn the engine on. Once you have seen an engine line you cannot un-see it, and your own reasoning — the entire diagnostic — is gone. It costs fifteen minutes a game and it is the highest-leverage habit on this site. Analyse Your Games runs the whole protocol over one complete game, so you can see what the fifteen minutes actually looks like.
