The rules every tournament player must know.

A game can end in a draw four ways. Know all of them.

Most beginners only think about winning by checkmate or losing by checkmate. But many tournament games end in a draw. Knowing the draw rules can save half a point (or cost you one) at a critical moment.

The four official draw rules are:

• Stalemate, the player to move has no legal moves but their king is NOT in check.
• Threefold repetition, the same position has appeared three times with the same player to move.
• The 50-move rule, 50 moves have passed with no pawn move and no capture.
• Insufficient material, neither side has enough pieces to deliver checkmate.

There's also draw by agreement, where both players shake hands and agree to a draw. This is common in higher levels. We will cover each rule below with a real position.

Stalemate, the most painful draw in chess.

Stalemate is when the player to move has zero legal moves, but their king is NOT in check. It is a draw, not a loss. Many winning positions have been thrown away by an opponent suddenly stalemating themselves.

To force stalemate (or avoid stalemating your opponent), you need to track two things every move: is the opponent in check, and do they have a legal move?

Threefold repetition, when the same position keeps coming back.

If the same exact position appears on the board three times, with the same player to move and the same options (castling rights, en passant), either player can claim a draw.

The positions do not need to be consecutive. They just need to appear three times total over the course of the game.

To claim the draw, you must:

• Notice the position has repeated three times (including this move).
• Stop the clock and tell the arbiter you are claiming threefold.
• Show your score sheet as evidence.

If you make the move that would create the third repetition without claiming, your opponent can also claim. After the move is played, you can no longer claim that specific repetition.

The 50-move rule, no progress means a draw.

If 50 consecutive moves are played by both sides with no pawn move AND no piece capture, either player can claim a draw.

50 moves means 50 by each side, so 100 half-moves total. The counter resets to zero every time a pawn moves or a piece is captured.

This rule prevents games from going on forever in technically drawn endgames. It also rewards players who know hard endgames (like K+B+N vs K, which CAN be won in less than 50 moves, but only with precise technique).

Insufficient material, when neither side can checkmate.

If neither player has enough pieces to deliver checkmate by any sequence of legal moves, the game is an automatic draw. The arbiter declares it without needing a claim.

Specifically, it is insufficient material if both sides only have:

• King vs King
• King + Bishop vs King
• King + Knight vs King
• King + Bishop vs King + Bishop (when both bishops are on the same colour squares)

With ANY pawn, rook, queen, or with two bishops or knight+bishop, checkmate IS possible (even if it's hard).

The touch-move rule. Touch a piece, move it.

In a tournament game, if you touch one of your own pieces, you MUST move that piece if a legal move is available. If you touch an opponent's piece, you MUST capture it if you can.

The rule is strict. It applies the moment your fingers touch the piece. Even an accidental touch counts, unless you said "j'adoube" (or "I adjust") FIRST.

• To adjust a piece (e.g. centre it on its square), say "I adjust" or "j'adoube" BEFORE you touch it.
• Once you let go of a piece on a new square, the move is final.
• If you touch a piece that has no legal moves, you can play any move you like.

The clock. When time runs out, you lose.

Every tournament game uses a chess clock that runs down. When your time hits zero, your flag falls. In most cases, this means you lose, even if you were winning on the board.

Key rules:

• Press the clock with the same hand you moved the piece. Two-handed moves are forbidden.
• Press immediately after your move, not while you're still deciding what comes next.
• If your flag falls and your opponent has enough material to checkmate, you lose. If they don't (e.g. they have only a king), the game is drawn instead.
• You must claim the flag. The arbiter does not stop the game automatically. If you don't notice your opponent's flag fall and you play on, the game continues.

Time controls vary by tournament. Common formats:

• Classical, 90+30 (90 minutes for the first 40 moves, then 30 minutes for the rest, plus a 30-second increment per move).
• Rapid, 15+10 or 25+10 (whole game in this time, with a 10-second increment per move).
• Blitz, 5+0 or 3+2 (very fast, often without increment).
• Bullet, 1+0 or 2+1 (online, not used in classical tournaments).

Etiquette. The unwritten rules.

Chess tournaments have a culture. Following the unwritten rules makes you welcome at any club, and shows you respect both the game and your opponent.

• Shake hands before the game and after the game, win or lose.
• Sit still and stay quiet at the board. Don't tap, hum, or distract.
• Don't speak to your opponent during the game, except to offer a draw, resign, or call the arbiter.
• Take losses well. Say "well played" and move on. Every strong player loses thousands of games on the way up.
• If in doubt, call the arbiter. Don't argue with your opponent. The arbiter is there to make rulings.
• Resign when the game is clearly lost. Playing on in a hopeless position is poor etiquette at higher levels. But never resign just because you're down a pawn, fight for every game.
