How to Run a Rapid Chess Tournament

Rapid is the sweet spot for most clubs, schools and office events. Games are long enough for real chess, short enough that four or five rounds fit into one evening or one Saturday, and nobody needs to write their moves down. This guide covers how to run a rapid chess tournament from start to finish: the time control, a realistic timetable, the clocks, the few rules worth announcing, and how to keep the day moving.

1 Pick Your Rapid Time Control

Rapid means each player has more than 10 minutes and up to about 60 for the whole game. It is written as minutes plus bonus seconds: 10+5 means 10 minutes each, and 5 seconds are added to your clock after every move. If you want the exact borders between bullet, blitz and rapid, see bullet vs blitz vs rapid.

Four controls cover almost every casual rapid event:

Time control	Feel	Best for
10+0	Quick, but the last minute gets scrappy	Schools, wind-up clocks, tight halls
10+5	Quick with a safety net	Club evenings, office events
15+10	Real thinking time, the classic rapid	Saturday rapidplays, keen clubs
25+10	Close to a slow game	Full day events with 4 to 5 rounds

Strictly speaking, FIDE counts 10+0 as blitz because it sits right on the border, but most clubs and schools call it rapid and that is fine for a casual event. Add any bonus and it is rapid by any rule. You can try each one on the free online chess clock, already set to 10+5.

2 Work Out How Long Each Round Takes

A round lasts as long as its slowest game, plus a few minutes to enter results and pair the next round. With a bonus, a long game of 40 to 50 moves each adds several minutes on top of the base time. Here is a realistic slot per round:

Time control	Longest normal game	Plan per round
10+0	20 min (it cannot go longer)	25 min
10+5	27 to 28 min	30 to 35 min
15+10	43 to 47 min	50 min
25+10	63 to 67 min	70 to 75 min

3 Choose How Many Rounds

Most rapid events are a Swiss: everyone plays every round, nobody is knocked out, and after round 1 players on the same score meet each other. The usual Swiss round counts are:

• 3 rounds for 4 to 7 players
• 4 rounds for 8 to 15 players
• 5 rounds for 16 to 23 players
• 6 rounds for 24 to 31 players

The free Swiss rounds calculator checks any number, and our guide on how many rounds a chess tournament needs explains why. With 6 to 8 players a round robin also works, where everyone plays everyone, but at 15+10 that is a long day: 8 players need 7 rounds.

Worked example 1: a club evening

12 players, 4 Swiss rounds at 10+5:

• Sign-in and setup: 15 minutes
• 4 rounds at about 30 minutes: 2 hours
• Results and prizes: 10 minutes
• Total: about 2 hours 25 minutes, so a 7:00 start finishes around 9:30

Worked example 2: a Saturday rapidplay

20 players, 5 Swiss rounds at 15+10:

• Sign-in: 30 minutes, from 9:30
• Rounds 1 to 3: 10:00, 10:50 and 11:40
• Lunch: 12:30 to 13:15
• Rounds 4 and 5: 13:15 and 14:05
• Prizes: around 15:00

Worked example 3: a school afternoon

14 kids, 4 Swiss rounds at 10+0. Kids' games are often quicker than the clock allows, so 25 minute slots are plenty. With 20 minutes to sign in and 15 for certificates, the whole event fits in about 2 hours 15 minutes. Our school chess tournament guide covers the rest of a school event.

4 Count Your Clocks and Boards

You need one clock and one board per pair, which is half your players rounded down. 20 players need 10 sets and 10 clocks. With an odd number, one player sits out each round with a bye, so 21 players still need 10.

• Digital clocks are needed for any control with a bonus, such as 10+5 or 15+10.
• Old wind-up clocks only work for controls with no bonus, like 10+0 or 15+0.
• Short of clocks? Any phone or tablet can run the free chess clock set to 15+10. Lay it flat between the players.

5 Announce the Rules Before Round 1

Rapid has fewer arguments than blitz, because players have time to think. Read these out once and most problems never happen:

• Touch move: touch a piece and you must move it. See the touch move rule for the details.
• Press the clock with the hand you moved with. Your move is not finished until you press it.
• No writing moves down. Score sheets are optional in rapid. If your players like recording games, the free printable chess score sheet works well.
• Illegal moves: the move is taken back, the player makes a legal move and the opponent gets some extra time. A second illegal move by the same player loses.
• Running out of time loses, unless the opponent cannot possibly checkmate, which is a draw.
• Phones away and on silent while you play, unless the phone is the clock.
• Both players report the result together at the end of the game.

For flags, bonus time and delay in more detail, see chess clock rules. You do not need a qualified arbiter for a club or school event. You need one person whose decision is final.

6 Keep the Day Moving

The schedule slips in three places, and all three are easy to fix:

• Sign-in. Close entries at a fixed time and start round 1 on the dot. Late arrivals can join from round 2 with no points, if you allow it at all.
• Pairing the next round. Pairing a Swiss by hand takes 5 to 10 minutes per round with a clipboard. Software does it the moment the last result is in.
• Breaks. A short break between rounds keeps players fresh, but an open-ended one eats the day. Give every break a fixed length and show it on a screen.

7 Running It With ChessHost

ChessHost is free chess tournament software that runs in a browser. Here is how a rapid event works in it:

1. Create the event: "New Tournament", give it a name, and pick the "Rapid" time control (10 min), or "Custom" for 15 or 25 minutes. New events are Swiss.
2. Players join by QR code: open "Invite Players", switch registrations to open, and put the QR at the door. Players join from their phone, no app and no account.
3. Rounds are worked out for you from the number of players. Change them in "Edit Tournament" under "Number of Rounds".
4. "Start Tournament" draws round 1. Enter each result by tapping the winner's half of the board, or "Draw".
5. Timed breaks: turn on the break timer in "TV Display", and "Start Next Round" offers a 5, 10 or 15 minute break that counts down on the TV.
6. Show it on a TV: the "TV Display" link works on any screen, so players find their board without crowding you.
7. Certificates at the end: "Finish Tournament", then "Share Options" and "Certificates" makes one for every player as a PDF.

ChessHost runs the pairings, byes and standings. The games are played on real boards with real (or phone) clocks: it does not time the games or give ratings.
