Console Chess

A simple chess game implemented in C# for the console.

Features

• All chess pieces with basic movements
• Special moves including castling, en passant, and promotion
• Legal move resolution to avoid putting oneself in check
• Detection of check and checkmate

Handling Special Moves

• Castling: Castling is handled automatically if the move involves the king and rook.

• En Passant: Automatically executed if a pawn moves two squares forward and lands beside an opponent's pawn.

• Promotion: If a pawn reaches the last rank, it is automatically promoted to a queen (or other piece if desired).

Checking Game Status

• Check: The game status will indicate if the current player is in check.

• Checkmate: The game will declare a checkmate if the opponent cannot move out of check.

Example Game Loop

while (!chessmatch.Finished)
{
    Console.Clear();
    Window.PrintMatch(chessmatch);

    Console.Write("Origin: ");
    Position origin = Window.ReadChessPosition().ToPosition();
    chessmatch.ValidateOriginPosition(origin);

    bool[,] possiblePositions = chessmatch.Board.piece(origin).PossibleMoves();

    Console.Clear();
    Window.PrintBoard(chessmatch.Board, possiblePositions);

    Console.Write("Destiny: ");
    Position destiny = Window.ReadChessPosition().ToPosition();
    chessmatch.ValidateDestinyPosition(origin, destiny);

    chessmatch.MakeMove(origin, destiny);
}

Handling Exceptions

Catch BoardException to handle invalid moves and other game-related errors:

{
    Console.WriteLine(e.Message);
