While most people are familiar with the basic rules of chess, there are some lesser-known and obscure rules that can add an interesting twist to the game.
Here we look deeper at some of these weird and obscure chess rules, providing valuable insights and examples along the way.
En Passant
En passant is a rule that allows a pawn to capture an opponent’s pawn under specific circumstances.
When an opponent moves their pawn two squares forward from its starting position, and it lands beside your pawn, you have the option to capture it as if it had only moved one square forward.
This capture must be made on the very next move, or the opportunity is lost.
For example, if your opponent moves their pawn from e7 to e5, and it lands beside your pawn on d5, you can capture it en passant by moving your pawn from d5 to e6.
This rule adds an element of surprise and strategy to the game, as players must be aware of the potential for en passant captures.
Castling
Castling is a move that allows the king and one of the rooks to move simultaneously.
It is a defensive move that helps to protect the king and develop the rook.
However, there are some specific rules that must be followed in order to castle:
- The king and the rook being castled must not have moved previously in the game.
- There must be no pieces between the king and the rook.
- The king must not be in check.
- The squares the king moves over during castling must not be under attack.
There are two types of castling: kingside and queenside.
Kingside castling involves moving the king two squares towards the rook on its original square, and then moving the rook to the square next to the king.
Queenside castling is similar, but the king moves two squares towards the rook on the opposite side of the board.
Queenside castling is less common than kingside castling, but can be common in certain positions such as the Sicilian Defense.
Promotion
When a pawn reaches the opposite end of the board, it has the opportunity to be promoted to any other piece (except a king).
This rule is known as promotion, and it allows pawns to transform into more powerful pieces, such as a queen, rook, bishop, or knight.
For example, if a pawn reaches the eighth rank (the opposite end of the board), the player can choose to promote it to a queen.
This can be a game-changing move, as it allows players to introduce a powerful piece into the game.
Stalemate
Stalemate is a unique situation in chess where a player whose king is not in check has no legal moves to make.
In this case, the game ends in a draw.
Stalemate can occur when a player’s pieces are poorly coordinated or when they are trying to force a win but inadvertently reach a position where their opponent’s king cannot be captured.
For example, if a player’s king is not in check but cannot move to any legal square without being captured, it is considered a stalemate.
This rule adds an interesting dynamic to the game, as players must be cautious not to accidentally reach a stalemate position.
Example
For example, in this following position, white needs to promote to a rook – and not a queen, like normal – otherwise this game will be a stalemate.
Threefold Repetition
The threefold repetition rule states that if the same position occurs three times in a game, with the same player to move, the game is considered a draw.
This rule helps to prevent players from endlessly repeating moves to avoid a loss or force a draw.
For example, if the same position occurs three times in a game, with the same player to move, the game is considered a draw.
This can happen when players are maneuvering their pieces and end up in a repetitive pattern.
Threefold reptition is common in perpetual check scenarios, where the queen keeps checking the king over and over again, like what could transpire in the following situation:
