As with blitz, the format is defined by the total time a player has for the whole game, counting the increment over an assumed sixty moves:
Typical rapid controls: 15+10, 10+5, 25+10, 20+0. The most common at amateur events is 15+10 - it fits a seven-round evening and still leaves time to think.
The classification is not academic: it decides which rating list the games go to and which rule set applies - blitz rules.
| Blitz | Rapid | Classical | |
|---|---|---|---|
| Notation | not required | usually not required | required |
| Illegal move | opponent may claim a win | usually added time, second offence loses | added time, second offence loses |
| Arbiter intervenes | on a claim | may intervene | intervenes |
| Rounds in an evening | 9-13 | 5-7 | 1-2 |
The exact treatment of illegal moves in rapid varies with the level of the event and with whether arbiters are supervising the boards, which is why it belongs in the regulations of any club event.
An increment changes the character of rapid more than anything else: with 15+10 a player is never left shuffling pieces on two seconds, and the endgame stays playable - about clocks and controls.
Generally no, and that is one of the main practical differences from classical chess. Most club rapid events do not ask players to record their games.
The consequences are worth knowing:
Practical advice for anyone trying to improve: write your games down even when nobody requires it. It costs nothing and turns an evening into study material - how notation works.
For a club evening rapid beats both neighbours, and not by a small margin.
The usual objection - that rapid means fewer games - is real, and it is a trade worth making: five remembered games beat twelve blurred ones - running a rapid event.
More than ten minutes and up to sixty per player for the whole game, counting the increment over an assumed sixty moves. Below that is blitz, above it is classical. Typical rapid controls are 15+10, 10+5 and 25+10.
Unlike blitz, it is usually not an instant loss: the position is restored and time is added to the opponent, with a second offence in the same game losing. The exact treatment depends on the level of the event, so it belongs in the regulations.
Usually not, though some official events with longer rapid controls require it. Worth doing anyway if you want to improve: a game that was not written down cannot be reviewed afterwards.
No, it must be claimed by a player, exactly as in blitz. And if your opponent cannot deliver mate by any legal sequence of moves, running out of time is a draw rather than a loss.
There is time to think, so games are decided by ideas rather than speed; five to seven rounds still fit into three hours; beginners blunder less and enjoy it more; mixed fields work better; and it is easier to arbiter because players can stop the clock and ask.
The Vibe Chess app opens from a link and needs no installation. Setting up a tournament takes a minute: pick the system, set the date, the venue and the time control - the app handles the rest.
for a large field: opponents are matched by score, you choose the number of rounds
for a small circle: everyone plays everyone, the round count follows from the field
no rounds, no pairings: players sign up and pick opponents at the table
The bot is constantly improved based on real tournaments. If you need a feature that isn't there yet, message the developers right inside the bot with the /support command. Many features appeared exactly because organizers asked for them, and useful ideas get added quickly.
Rules - blitz, draws, notation. Formats - a weekend rapid.
