• Accepts input of the form "FileRank FileRank".

  • The first "FileRank" indicates the coordinates of the piece to be moved, and the second indicates where to move it to.

  • For example, moving white Pawn e2 => e3:

    ---------------------------
    White move: e2 e3
    

• Castling move

  • Using where the king begins and ends.

  • For example, move white King e1 => g1, and white Rook h1 => f1:

    ---------------------------
    White move: e1 g1
    

• Pawn Promotion

  • Append the piece to be promoted after the move with a space.

  • If no promotion is indicated, assumes it promote to a Queen.

  • For example, moves white Pawn p7 => p8, and promote it to a Knight:

    ---------------------------
    White move: g7 g8 N
    

Ending the game:

• Resign:

  • A player can resign by entering "resign".

  • For example, white player resigns:

    ---------------------------
    White move: resign
    

• Draw:

  • Offer a draw by appending "draw?" to the end of an otherwise regular move.

  • For example:

    ---------------------------
    White move: e1 g1draw?
    

  • The draw can be acceped by the other player entering only "draw" on the next move.

    ---------------------------
    Black move: draw
    

• At the end of the game:

  • The program will prints out "White wins", "Black wins", or "draw".
