🖐 Touch-Move (The Big One)

The touch-move rule is strict; once you deliberately touch a piece, you are committed to moving it.

• If you deliberately touch one of your own pieces, you are expected to move it (if legal).
• If you touch an opponent piece, you may be expected to capture it (if legal).
• If you need to adjust a piece, say “I adjust” first, then adjust.

⚠ Illegal Moves

Handling varies by event and federation, but your safest mindset is: make moves slowly and clearly when anything tactical or unusual is happening.

• Don’t rush castling / en passant / promotions.
• If you’re unsure, pause and check the board carefully.

👨‍⚖️ When to Call the Arbiter

• If there’s a disagreement about a rule
• If a clock or board issue occurs
• If you need a ruling and can’t resolve it calmly

Best practice: call the arbiter politely and explain the situation simply.

⏱ Clock-Related Basics

• Press the clock after completing your move.
• Don’t press while your hand is still on the piece.
• If the clock behaves strangely, call the arbiter.
