A draw in chess that occurs when the same position is repeated three times with the same player to move and the same possible moves available.
Introduction
Threefold repetition is a rule in chess that allows a player to claim a draw if the same position appears on the board three times with the same possible moves for both players. This rule prevents endless loops and forced losses, making it an essential part of competitive chess.
How does threefold repetition work? How can you claim it in tournaments or online games? And how do grandmasters use this rule strategically? This article explores the mechanics, strategies, and famous cases of threefold repetition in chess.
1. What Is Threefold Repetition?
A position is considered repeated if:
✔ The same pieces are on the same squares.
✔ The same player is to move.
✔ All possible legal moves (castling and en passant included) remain unchanged.
✅ Example:
- White and Black repeat moves three times in a row, and White claims a draw.
1.1 Important Conditions
✔ The repetitions do not have to be consecutive.
✔ A player must claim the draw before making a move.
✔ It applies in all game phases: opening, middlegame, and endgame.
✅ Example of a Threefold Repetition Draw:
- White plays Qd3 → Qe3 → Qd3 → Qe3 → Qd3 (same position occurs three times).
- White claims a draw by threefold repetition.
2. How to Claim Threefold Repetition in Tournaments?
✔ Write down the move that will cause the third repetition on your scoresheet.
✔ Stop the clock and notify the arbiter before making the move.
✔ The arbiter will check the scoresheet and confirm the draw.
✅ Example:
- A player writes Kg1 on the scoresheet, stops the clock, and claims threefold repetition before playing the move.
3. How to Claim Threefold Repetition Online?
✔ On Chess.com and Lichess, the system automatically detects threefold repetition.
✔ If the same position appears three times, players can click ‘Claim Draw’.
✔ If a player does not claim, the game continues.
✅ Example:
- A player repeats a knight check three times, and the online server offers the option to claim a draw.
4. Strategic Uses of Threefold Repetition
4.1 Saving a Draw in a Losing Position
- If a player is losing, they can force threefold repetition to escape defeat.
✅ Example:
- White forces perpetual check, repeating moves and securing a draw instead of a loss.
4.2 Forcing a Draw Against a Stronger Opponent
- In tournaments, players use repetition to draw against higher-rated opponents.
✅ Example:
- A lower-rated player forces repeated checks, securing a draw against a grandmaster.
4.3 Psychological Pressure
- A player may repeat moves twice, making the opponent hesitate before continuing the game.
✅ Example:
- A grandmaster repeats moves twice to gain time on the clock before deciding on a strategy.

6. Common Mistakes When Claiming Threefold Repetition
❌ Not Claiming the Draw Before Making the Move → Once a move is made, the opportunity is lost.
❌ Thinking the Repetitions Must Be Consecutive → They do not need to happen in a row.
❌ Forgetting Castling and En Passant Rules → If castling or en passant is still possible in one position but not another, they are not identical positions.
❌ Assuming the Opponent Has to Accept → Threefold repetition is a forced draw if claimed, but if not claimed, the game continues.
✅ Example of a Mistake:
- A player plays the move before claiming and loses the right to claim the draw.
