Platform Rules

• Standard FIDE chess rules apply to all games played on Sacrifice.pro
• No takebacks are allowed during competitive play
• Resignation immediately ends the game
• Draw offers can be made and accepted or declined by the opponent
• Games are timed — running out of time results in a loss (unless the opponent has insufficient material)
• All moves must be made within the allotted time control and increment

Fair play is the foundation of competitive chess. All players must adhere to the following standards:

• No external assistance: You must not use chess engines, analysis tools, books, databases, or any other form of assistance during a game
• No coaching: You must not receive advice from other people during a game
• One account only: Each person may only have one account on Sacrifice.pro
• No account sharing: Your account must only be used by you
• No sandbagging: Deliberately losing games to lower your rating is prohibited
• No collusion: Arranging results with other players is strictly forbidden

• Players must be ready to play when their match is scheduled to begin
• Failure to show up for a scheduled game may result in forfeiture
• Entry fees are non-refundable once a tournament has started
• Prize distribution follows the tournament's specified structure
• Tournament-specific rules (if any) will be displayed on the tournament page
• Administrators reserve the right to make final decisions on any disputes

For details on specific tournament formats, see our format guides: Head to Head, Hybrid Knockout, and League.

• Each tournament specifies its time control and increment
• Your clock starts when it becomes your turn to move
• The increment (if any) is added after you make your move
• If your flag falls (time runs out), the game is lost — there are no exceptions
• Deliberately letting your clock run down in a clearly lost position is considered poor sportsmanship

• Treat all players with respect and courtesy
• No abusive, offensive, or discriminatory language
• No harassment of any kind, including in chat, forums, and direct messages
• Respect the outcome of games — no excessive complaints or blame
• Report genuine concerns through the proper appeals process

For full details, see our Code of Conduct.
