Chess

A barebones version of command-line Chess for 2 players.

Although currently missing the feature that declares Check, it is completely playable and includes all special moves(castling, en passant, promotion, and a pawn's double step on its first move).

TODO:

  1. Declare Check/Mate
  2. En-Passant(first-turn) restriction

Gameplay

The game is played on a standard 8x8 board as shown below.

  A B C D E F G H

A user will first be prompted to select a chess piece belonging to his/her color. Once a the chess piece has been chosen, he/she will then be prompted to select a space to move that chess piece.

Basic Commands

To enter a command, simply type in the X and Y coordinate without any spaces or commas seperating the two. Eg. A2, H7 or B6 (Lowercases are also accepted).

If a command is invalid, the use will be alerted and prompted again until a valid command is entered.

Special moves

All special moves (castling, en passant, promotion, and a pawn's double step on its first move) are recognized and allowed.

Note:

i) To initialize Castling, select Rook THEN select King. Restricted by Check not applied yet.
