Special Rules

1. Castling - King and Rook Joint Move

🏰 Essential safety maneuver!

Castling allows you to move the king and rook simultaneously, helping protect your king and activate your rook.

🔸 Kingside Castling (O-O)

With the kingside rook. King moves to g1/g8, rook moves to f1/f8

🔸 Queenside Castling (O-O-O)

With the queenside rook. King moves to c1/c8, rook moves to d1/d8

Castling Requirements:

  • ✅ King and rook have never moved
  • ✅ No pieces between king and rook
  • ✅ King is not in check
  • ✅ King doesn't pass through a square under attack
  • ✅ King doesn't end up in check

2. En Passant - Special Pawn Capture

👻 Unique pawn capture rule

When an enemy pawn moves two squares from its starting position and lands next to your pawn, you can capture it "in passing" on the very next move only.

Requirements:

  • • Enemy pawn must move two squares and land adjacent to your pawn
  • • Must be captured immediately on the next move
  • • Move to the square the pawn passed over and remove the captured pawn

3. Pawn Promotion

⬆️ Transform your pawn!

When a pawn reaches the opposite end of the board (8th rank for white, 1st rank for black), it must promote to a queen, rook, bishop, or knight.

Promotion Choices:

  • • 👑 Queen (most common choice)
  • • 🏰 Rook, 📐 Bishop, 🐎 Knight
  • • Can choose any piece, even if not captured

Important Notes:

  • • Promotion happens as part of the move
  • • Promotion is mandatory, not optional
  • • Multiple queens are possible

Check, Checkmate & Stalemate

Check

King is under attack

Must respond by:

  • 1. Moving the king to safety
  • 2. Capturing the attacking piece
  • 3. Blocking the attack

Checkmate

King is in check with no escape

Game over immediately!

No legal move can save the king

Stalemate

No legal moves but not in check

Draw

Unique chess draw condition

Draw Conditions

Automatic Draws

  • Stalemate: No legal moves, not in check
  • Insufficient Material: Neither side can force checkmate
  • Fivefold Repetition: Same position occurs 5 times
  • 75-Move Rule: 75 moves without pawn move or capture

Claimable Draws

  • Threefold Repetition: Same position occurs 3 times (claim required)
  • 50-Move Rule: 50 moves without pawn move or capture
  • Mutual Agreement: Both players agree to draw

Touch-Move Rule

✋ If you touch it, you must move it

  • Touch your own piece: Must move that piece if a legal move exists
  • Touch opponent's piece: Must capture it if legally possible
  • Adjusting pieces: Say "I adjust" (or "j'adoube") before touching

Frequently Asked Questions

Can the king be captured?
No. The king is never actually captured. The game ends immediately when checkmate occurs.
How is castling written in chess notation?
Kingside castling is written as O-O, queenside castling as O-O-O.
What's the difference between the 50-move and 75-move rules?
The 50-move rule requires a claim, while the 75-move rule is automatic. Same principle applies to threefold vs. fivefold repetition.

Yes. When a pawn reaches the back rank, it must promote to a queen, rook, bishop, or knight as part of that move.
