Blitz, rapid or classical: which time control should you play?

Blitz is 10 minutes or less per player, rapid is over 10 and under 60, classical is 60 or more. What each one trains, and how to choose one to improve.

Updated 12 November 2026 · 6 min read

Under FIDE's Laws of Chess, a blitz game gives each player 10 minutes or less, a rapid game more than 10 but less than 60 minutes, and a standard (classical) game at least 60 minutes. With an increment, count the starting time plus 60 times the increment. If you want to improve, play mostly rapid or slower, where you have time to think, check for blunders and use what you learn. Play blitz or bullet for fun and quick pattern practice, and review those games afterwards.

The official definitions

FIDE, the world chess federation, sets these in its Laws of Chess, applied from 1 January 2023.

The first number is each player's starting time in minutes; the second is the increment, seconds added to your clock for each move, so a long game doesn't end in a scramble. FIDE counts 3 + 2 as 3 minutes + 60 × 2 seconds = 5 minutes: blitz. It counts 15 + 10 as 15 + 10 = 25 minutes: rapid.

FIDE's rating lists draw the lines a little differently. A game is rated for the blitz list only if each player has more than 3 and at most 10 minutes (Rapid and Blitz Rating Regulations, section 1.1.2). A game counts for the standard list only with enough time for 60 moves: at least 120 minutes each if a player is rated 2400 or more, 90 minutes if a player is rated 1800 or more, and 60 minutes if both are below 1800 (FIDE Rating Regulations, section 1.1). Both regulations apply from 1 March 2024.

What each time control trains

Bullet and blitz reward speed: recognising patterns at a glance, knowing your openings and handling the clock. They're fun and quick, but there's little time to calculate, so you mostly repeat your habits, good and bad. Many fast games are decided by a blunder or the clock rather than the better plan.

Rapid is the middle ground. At 10 to 15 minutes you can stop at the critical moments, count the material, look at your opponent's threats and calculate a few moves ahead, and a game still takes under half an hour.

Classical gives you time for everything: planning, deep calculation and accurate endgames. Over-the-board tournaments are mostly classical. It's the best test of what you really understand, but a single game can take hours.

Which one should you play?

There's no single right answer, but these rules of thumb help.

• To improve: play mostly rapid, 10 minutes or more, preferably with an increment such as 15 + 10. Use the time to run the 5-question blunder checklist before every move that matters.
• If you're new: start without a clock or with a long one. Learning how the pieces move and what's attacked is hard enough without time pressure.
• If you only have five minutes: a blitz game or a few puzzles is better than nothing. Puzzles train the same pattern recognition as blitz, without the clock deciding for you.
• If you play in tournaments: practise at the time control you'll play there, so the clock doesn't surprise you.
• Whatever you play: review your games, especially the losses. A fast game you review teaches more than five you don't.

Your rating will usually differ between time controls, and that's normal. Sites keep a separate rating for each, so compare like with like. What is a good chess rating? explains why.

Time controls on ChessMess

ChessMess has clocks from 1 minute to 30 minutes, plus "No clock" for relaxed games against the bots and with friends. The online games, against AI opponents matched to your level, offer nine clocks from 1 + 0 to 30 + 0.

ChessMess keeps a separate Glicko-2 rating for bullet, blitz, rapid and classical. Like many chess sites, it sorts a game by its estimated length: the starting time plus 40 times the increment.

So a 30-minute game counts as "classical" in your ChessMess ratings, while FIDE would call it rapid, and 10 + 0 counts as rapid here although FIDE calls it blitz. Online sites use shorter bands because few people play two-hour games online.

Make the most of any time control

1. Pick one time control and stay with it for a few weeks, so your rating means something.
2. After each game, open Game Review. It's free and unlimited, and it shows where the game turned.
3. Turn your mistakes into practice in the Mistake trainer.
4. If you often lose on time, add an increment or move up one time control.

Questions and answers

What is the difference between blitz and rapid chess?

Time. Under FIDE's Laws of Chess, blitz gives each player 10 minutes or less and rapid more than 10 but less than 60 minutes. With an increment, add 60 times the increment to the starting time before comparing.

How long is a classical chess game?

FIDE's Laws call a game standard (classical) when each player has at least 60 minutes. For a standard rating, FIDE needs at least 60, 90 or 120 minutes each, depending on the players' ratings.

Is 10 minutes blitz or rapid?

Under FIDE's definitions, 10 + 0 is blitz, because blitz is 10 minutes or less. Many online sites, ChessMess included, count 10 + 0 as rapid, because they sort games by estimated length with different bands.

Which time control is best for improving at chess?

Mostly rapid or slower, 10 minutes or more and ideally with an increment, so you have time to check for blunders and calculate. Review your games afterwards, whatever the time control.

What does 15 + 10 mean in chess?

Each player starts with 15 minutes and gets 10 extra seconds after every move. FIDE counts it as 15 + 60 × 10 seconds = 25 minutes, which makes it a rapid game.
