Chess Console Game

Play the game hosted on Replit.

This is a console or command-line implementation of the classic two-player board game Chess that lets players input their moves using a custom form of Long Algebraic Notation. Players can choose to either play against another human player or a simple computer player / bot. Games can be saved and loaded from save files.

For the details on the game and its custom Long Algebraic Notation, see the Specifications document.

For additional demonstration video recordings, see the Demonstrations document.

Chess pieces are printed on the chess board as 2-character strings composed of a lowercase and an uppercase alphabetical English characters e.g. bP for a Black Pawn. The first character is either b or w which denotes the color of the piece as black or white respectively. The second character denotes the type of chess piece it is.

The letter to piece mappings are as follows:

• P: Pawn
• R: Rook
• N: Knight
• B: Bishop
• Q: Queen
• K: King
