Practise 5 days. Find out what is really costing you games.
Most players practise without ever learning which part of their chess is holding them back. Practise five days in a row and Chess Nexus analyses every game you played — on Chess Nexus, Chess.com and Lichess together — and tells you exactly what to work on next.
What a practice day costs
A day only counts when you do all three. Opening the app does not count, and neither does one quick puzzle — the streak is a record of real work, which is what makes the report worth reading.
- 10 puzzlesAny mode counts — Healthy Mix, themes, by piece count or by rating band.
- 1 gameOn Chess Nexus, Chess.com or Lichess. Blitz, rapid or classical — bullet and variants do not count, because their mistakes are usually the clock rather than your chess.
- 1 endgamePlayed out against the computer, from any position in the endgame library.
One report, all three platforms
Analysing a game tells you what happened in that game. This pools everything you played over five days — wherever you played it — and tells you what is happening to your chess. That is a different question, and a more useful one.
What the report tells you
Not a wall of engine lines. Six things a coach would actually point at, each drawn from the games you really played.
- Which phase is holding you backYour accuracy in the opening, middlegame and endgame separately, with the blunders, mistakes and inaccuracies in each — and the weakest one marked.
- How well you defendHow often a game turned against you, how many of those you saved, how many collapsed, and how long you resisted on average. Almost nothing else measures this.
- The endgames you actually reachedRook endgames, king and pawn, queen endings — how many came up and your record in each. Losing the same type repeatedly is a fixable problem once you can see it.
- What the clock costs youHow much worse you play with under a minute left than with time to think — and how many of your blunders came from there.
- Whether you finish won gamesHow often you reached a winning position, and how often you actually won from it.
- Where your mistakes happenEvery blunder grouped into tactics, defence, calculation, endgames and opening — click a group and replay those exact positions.
A study plan built from your own mistakes
The report does not stop at telling you what is wrong. Every finding becomes something to do:
- Lost rook endgames?Get rook endgames with the same material to play out against the engine.
- Kept missing forks?Go straight to fork puzzles, until you stop missing them.
- Weak middlegame?Replay your own middlegame blunders and find the move you should have played.
Compare four reports and watch a month of progress
Reports are kept and shown side by side, like comparing specifications. Each column is one five-day period; each row a measure — rating, accuracy, blunders per game, accuracy in each phase — with the change from last time underneath. Because every report covers a distinct five days rather than a rolling window, a difference between two columns is real change in your play, not an artefact of the dates moving.
Why a streak, and not just a button
Improvement comes from turning up regularly, and one analysed game tells you very little. Five days of real practice is enough games to say something true about your chess — which is why the report is earned rather than simply available. The streak keeps running after you claim one: day 10, day 15 and day 20 each unlock another, so a long run is never reset as a reward for succeeding.
Frequently asked questions
What is the 5-day practice streak?
Practise chess five days in a row on Chess Nexus and you unlock a full report on how you have been playing. A day counts when you solve 10 puzzles, play one standard game (on Chess Nexus, Chess.com or Lichess) and play out one endgame against the computer. Simply opening the app does not count — the streak is about real practice.
What is in the weekly chess report?
Your accuracy in the opening, middlegame and endgame separately, with the blunders, mistakes and inaccuracies in each; how well you defend when a game turns against you; which endgames you actually reached and your record in them; the openings you played; how much worse you play under a minute on the clock; how often you converted a winning position; and every mistake you made grouped into tactics, defence, calculation, endgames and opening — each one replayable.
Does it include my Chess.com and Lichess games?
Yes. The report analyses every standard game you played in those five days across Chess Nexus, Chess.com and Lichess together — which is what makes it different from analysing one game on one site. Save your usernames in your profile so those games are counted. Bullet and variants such as Chess960 are left out, because their mistakes are mostly clock panic rather than chess.
Does my streak reset after I get a report?
No. The streak keeps running: day 10, day 15 and day 20 each unlock another report, and a 30-day streak stays a 30-day streak. Each report covers the five days since the last one, so no two reports overlap.
What does the report cost?
100 XP, which is roughly what five days of practice earns — so the streak pays for its own report. It is free for coaches, Nexus Elite members and coffee supporters.
How is this different from analysing a single game?
Analysing a game tells you what happened in that game. The report tells you what is happening to your chess: it pools a whole period across all three platforms, shows which phase of the game is holding you back, and turns each finding into a specific drill. Keep several reports and you can compare them side by side to see what is genuinely improving.
What is Defender Training?
It measures something almost nothing else does: how well you hold a bad position. The report counts how often you fell into a clearly worse position, how many of those you saved or held, how many collapsed, and how many moves on average you resisted before it fell apart. Many players resign mentally at minus two; the ones who improve fastest are usually the ones who defend.
