Correspondence Chess: Play Slow, Deep, Turn-Based Games Online
Correspondence chess is chess played over hours, days, or even longer rather than in one sitting. You do not need to be online at the same time as your opponent, so the format suits busy players, returning players, and anyone who prefers careful analysis over clock pressure.
You may also see it called daily chess, turn-based chess, postal chess, chess by mail, or email chess. The basic idea is the same: the game is not live, and each move can be considered carefully.
The quick answer
Correspondence chess is a long-form version of chess where players make moves remotely and usually have a day or more for each move. Modern correspondence chess is usually played on servers, while older forms were played by post or email.
- Not live chess
- Usually one or more days per move
- Often several games at once
- Ideal for deeper calculation
- Rules on outside help vary by platform
Why correspondence chess appeals to so many players
Fast chess rewards speed, nerve, and practical decisions. Correspondence chess rewards patience, memory, structure, and long-term planning. That makes it attractive to players who want serious games without having to clear an uninterrupted hour in the day.
Important: “Correspondence chess” is the format, not one universal fair-play rulebook. Some official correspondence environments allow much more outside assistance than typical daily-chess sites, while others keep the game human-only. Always check the exact rules of the server, federation, or event you are entering.
Correspondence chess vs daily chess vs postal chess
These terms overlap, but they are not always used in exactly the same way.
How a typical turn-based chess game works
The format is simple, but a good routine matters. A calm, repeatable process usually scores better than random bursts of analysis.
- Open the position and identify immediate threats.
- List two or three candidate moves rather than jumping at the first idea.
- Check forcing lines first: checks, captures, threats, and tactical refutations.
- Compare plans, pawn structure, king safety, and piece activity.
- Only then commit to the move and record any useful notes for later.
The best correspondence habits are slow, organised, and consistent.
What makes strong correspondence players strong
Many newer players assume everyone should draw with perfect play if they have lots of time. In practice, people still lose for very human reasons.
- Better opening preparation
- Better move selection discipline
- Stronger evaluation of quiet positions
- More patience in defence
- Cleaner note-keeping and time management
- Better endgame conversion
- Fewer emotional decisions
- Greater consistency across many games
Why people still lose in correspondence chess
Extra thinking time reduces blunders, but it does not remove them. Players still lose because they mis-evaluate, trust the wrong plan, drift into a worse ending, mishandle time, or simply choose the wrong move after long analysis.
A common practical mistake is to spend too much time proving a move is playable and not enough time proving a different move is stronger. Correspondence chess punishes false confidence more than quick nerves.

How long does a correspondence chess game last?
The answer depends on the move limit. A one-day-per-move game can finish in a few weeks if both players move promptly. A three-day or seven-day format can stretch much longer. Traditional postal games could last years.
What is allowed in correspondence chess?
This is where many players get confused. There is no single universal answer.
Practical rule: if a site says “no engine help,” do not use engine analysis, engine-backed explorer lines, or anything that gives engine-generated move recommendations for your live game. When in doubt, play it as a human-only game.
Is correspondence chess good for improvement?
It can be excellent for improvement if you treat it as a study discipline rather than a way to outsource decisions. The format naturally rewards careful candidate-move thinking, opening structure, deeper endgame attention, and less impulsive play.
- Good for opening memory and structure
- Good for disciplined calculation
- Good for note-taking and post-game review
- Good for players with limited continuous free time
- Less useful if you just copy moves without understanding them
A short history of chess by mail and remote play
Before web servers, players exchanged moves by post. Later came email and then database-driven chess servers. The core appeal never changed: serious chess without needing both players to sit at the board at the same moment.
Postal chess is not a separate game from chess itself. The board, pieces, and rules are the same. What changes is the time horizon and the thinking process.
Ready for a slower, more thoughtful way to play?
If you enjoy long-form planning, careful analysis, and games that fit around real life, correspondence-style chess can be one of the most satisfying ways to play.
Common questions about correspondence chess
These answers are written to be clear on their own, because most confusion around correspondence chess comes from mixed terminology and mixed rule sets.
Definitions and basics
What is correspondence chess?
Correspondence chess is chess played remotely with long time controls, usually giving each player a day or more for each move. The game is not played in one sitting, so players can think between moves and often run several games at once.
What does correspondence mean in chess?
In chess, correspondence means the moves are exchanged over distance rather than face to face at a board. Historically that meant letters or postcards; today it usually means a website, server, or email.
Is correspondence chess the same as daily chess?
Daily chess is a modern online form of correspondence chess. The core idea is the same, but “daily chess” usually refers specifically to server-based games with one or more days per move.
Is correspondence chess the same as turn-based chess?
Turn-based chess is usually another name for correspondence-style chess. The phrase emphasises that the players do not need to be online together and that each move can be made later.
What is postal chess?
Postal chess is the traditional form of correspondence chess where moves are sent by post. It is the historic ancestor of modern daily chess and email chess.
Rules and fair play
Can you use an engine in correspondence chess?
Engine use depends entirely on the platform or event. Some official correspondence organisations allow engine assistance, while many daily-chess websites and human-only events ban it completely.
Can you use opening books in correspondence chess?
Opening books and general reference material are often allowed in traditional correspondence settings, but not every platform follows the same rulebook. Always read the event rules before assuming anything is permitted.
Is using a physical board allowed in correspondence chess?
Using a physical board is commonly accepted in many correspondence-style environments because the format is built around slower analysis. However, the exact answer still depends on the platform’s published rules.
Is correspondence chess cheating?
Correspondence chess is not cheating. Correspondence chess is a legitimate format of chess, but the fair-play boundary depends on the competition you enter. What is legal in one environment may be illegal in another.
Why is there so much confusion about cheating in daily chess?
The confusion comes from different platforms using different rules. Many players hear that engines are allowed in some correspondence competitions and wrongly assume that the same rule applies everywhere, which it does not.
Practical play and improvement
How long does a correspondence chess game last?
A correspondence chess game can last from a few weeks to many months, depending on the time control and how quickly both players move. Traditional postal games could last much longer.
Why do people play correspondence chess?
People play correspondence chess because it fits around real life and rewards deeper thinking. It appeals to players who like careful planning, reduced time pressure, and the chance to play serious games without fixed scheduling.
Is correspondence chess good for improvement?
Correspondence chess can be very good for improvement when you use the extra time to analyse honestly and learn from your choices. It is especially useful for openings, strategic planning, and disciplined calculation.
How do people win in correspondence chess if both sides have so much time?
People still win because chess positions remain difficult even with extra time. Better evaluation, stronger planning, cleaner defence, superior endgame handling, and fewer practical mistakes still create decisive results.
Can beginners play correspondence chess?
Beginners can absolutely play correspondence chess. In fact, the slower pace can make the game less stressful because there is time to think, check threats, and avoid rushed blunders.
Titles, status, and misconceptions
Can you earn titles in correspondence chess?
Yes, correspondence chess has its own recognised title systems in official organisations. Those titles are specific to correspondence play and are not the same thing as over-the-board FIDE titles.
Is correspondence chess respected?
Correspondence chess is respected as its own discipline, but people value different forms of chess for different reasons. It is best understood as a separate competitive format rather than a replacement for over-the-board play.
Is correspondence chess just for people who do not want to play live chess?
No. Many players enjoy both live chess and correspondence chess because they test different strengths. Live chess rewards practical speed under pressure, while correspondence chess rewards deeper long-range judgment.
Is correspondence chess still a thing today?
Correspondence chess is still very much active today. Most of it now happens on web servers and daily-chess platforms rather than through the postal system, but the format remains popular.
