Some Features

● PROMOTION It is a feature especially for the pawn piece if it reaches the end of the opponent’s side. The player will be able to exchange the pawn with ( Queen or knight or bishop or rook). The way user enters it : when player_1 enters A7A8 message of promotion appears”choose the promotion('q','n','b',r'): “ then player_1 enter piece: q If a player enters other than those mentioned, “enter a valid piece” message will be printed and he will be asked to enter a piece again.

● CHECK if any piece of a player is attacking the opponent’s king, the program will print “CHECK!”. At this point, the checked player will only be able to move a piece that eliminates the threat on the king. If he moves any other piece, “Illegal Movement” message will be printed and this player will be asked to enter another movement.● CHECKMATE if the king is in check and there is no piece able to block the attacker or to capture the attacker or the king could move from its place. The program prints “checkmate” and ends the game.

● STALEMATE If the king of the player whose turn to play is not in check and every move of this player leads to checking his own king i.e No valid move for the player and no check, the game is ended as “Draw by Stalemate”.

● DEAD POSITION If checkmate became impossible, i.e No player could checkmate the other player by any number of legal chess movements, the game is ended as “Draw by dead position”. It arises when:

1. Only the two kings are remaining.
2. Only the 2 kings and one knight are remaining.
3. Only the 2 kings and a bishop are remaining.
4. Only the 2 kings and two bishops of the same colour are remaining.

● CASTLING This feature is special for the king and the rook where the user is able to move the king 2 squares and the program moves the rook directly to the other side of the king. This occurs if the following conditions are satisfied:

1. The king is not in check and not moving to check or through check.
2. Both the king and the rook didn’t move before.
3. there are no pieces between king and the rook. There are two types of castling which is king side castling (when king moves to right) and queen side castling(when king moves to the left).

● SAVE AND LOAD The user is able to save the game at any time and load it again later. How the user enters it: when it is the player turn: if he writes ‘s’ the program will ask the user to enter the file name in which the game will be saved. When the game is saved, “File is saved successfully!” message will be printed.

● UNDO A player is able to undo movements any number of times till the first move played. How the user enters it: Whenever he writes ‘u’, the last movement will be undone. If a player writes the undo command and there are no previous moves, A “No Previous Movements!” message will be printed.

● REDO A player is able to redo movements any number of times till the last move played. How the user enters it: Whenever he writes ‘r’, the following movement will be redone. If a player writes the redo command and there are no following moves, A “No Following Movements!” message will be printed
