• Time control follows FIDE handicap rules (Bullet 1+0, Blitz 3+2, Rapid 15+10) unless otherwise stated.
• Touch-move applies in over-the-board tournaments. On the platform, drag-and-drop is final once released on a square.
• A draw can be claimed under threefold repetition or 50-move rule via the in-game UI.
• Disconnections under 60 seconds resume automatically. Beyond that, the round is awarded to the connected player unless an arbiter intervenes.
• Arena tie-breaks: Buchholz Cut-1, then Sonneborn-Berger, then direct encounter, then drawing of lots.

• Initial rating is 1200 after 3 rated games (provisional).
• K-factor: 40 (under 18 games), 25 (≤ 2300), 15 (above 2300).
• Variant ratings (Blitz, Bullet, Rapid, Classical) are tracked independently.
• Inactivity: ratings decay by 25 points after 12 months of inactivity, restored on first rated game.

• Each school enters at least one team of 4 (board 1 highest-rated).
• Substitutions allowed before round 1 — no substitutions after the first move of round 1.
• Coaches may not analyse with players during a round.
• School points = total individual points across boards. Tie-breakers as in arena rules above.

• No insults, harassment, or discrimination on any platform channel.
• No external coaching, engine, or database access during rated play or tournaments.
• No multiple accounts. Penalty: deletion of duplicate accounts and rating reset.
• Streaming: allowed with 30-minute delay during rated tournaments.

Concerns raised during a tournament are decided by the on-site arbiter. Off-platform disputes may be appealed within 7 days to arbiters@dchessacademy.com. The Appeals Committee's decision is final. Major decisions (account bans, rating resets, disqualifications) may be referred to the Federation as needed.
