Rules & Draws

The Three Ways to Win

• Checkmate — the king is in check with no legal way out. The game ends immediately.
• Resignation — a player can resign at any time, conceding before an inevitable checkmate actually occurs. Most games between strong players end this way, not with an actual mate on the board.
• Time forfeit — in games played with a clock, running out of time is an immediate loss, even from a completely winning position (with one exception: a player cannot win on time if their opponent has no way to deliver checkmate with any sequence of legal moves — that's a draw instead).

The Five Ways to Draw

• Stalemate — the player to move has no legal move at all, and their king is not currently in check. Instead of a loss, this is an immediate draw — one of chess's most distinctive rules, and a genuine escape hatch that has rescued countless lost positions.
• Threefold repetition — if the exact same position (with the same player to move and the same rights to castle or capture en passant) occurs three times, either player may claim a draw.
• The fifty-move rule — if fifty consecutive moves pass, by both players, with no pawn move and no capture, either player may claim a draw. It exists to prevent a hopeless side from being tortured forever in a position neither side can actually make progress in.
• Insufficient material — if neither side has enough material left to deliver checkmate under any sequence of legal moves (for example, king vs. king, or king and a single minor piece vs. king), the game is an automatic draw.
• Draw by agreement — either player may simply offer a draw at any point, which the opponent can accept or decline.

Touch-Move and J'adoube

Under the official touch-move rule, deliberately touching one of your own pieces obligates you to move it, if it has any legal move at all — and touching an opponent's piece obligates you to capture it, if a legal capture is available. The one exception: saying "j'adoube" (French for "I adjust") before touching a piece purely to straighten it on its square, without any intention of moving it, is always allowed.

Time Controls

Competitive chess is played under a range of time controls, each producing a noticeably different style of game:

• Classical — the slowest and most traditional format, typically 90 minutes or more per player for the whole game, sometimes with an added increment (extra seconds credited after every move). This is the format used for World Championship matches and most elite tournaments.
• Rapid — roughly 10–60 minutes per player, fast enough for several games in a single day, slow enough to still allow real calculation.
• Blitz — roughly 3–10 minutes per player, prioritizing speed and instinct over deep calculation.
• Bullet — under 3 minutes per player total, played almost entirely on pattern recognition and reflexes rather than calculation.

Many events also use an "increment" or "delay" — a few extra seconds added to a player's clock after each move — specifically to prevent completely lost or drawn positions from being decided by a pure time scramble rather than the position on the board.
