• Are any unique methods needed here, can castling all be done from the King method?

• check this is needed

Create methods for check a. this method wil need to run every turn. I may also need to create a method in the King class itself to ensure that it doesn't put itself in check/mate, this will now be done in this class.

• Create a method where for the player it identifies if they are in check at the beginning of their go
  • Communicate that the king is in check
  • Make sure that if the players piece is in check that the only move which can make will bring the piece out of check
• Make a method which does not let the player intentionally put their king into check
• Make a method which identifies if yo have put the opposition into check
• This should be communicated to the player
• Once check has been established checkmate should then be looked for by searching for check on all of the kings potential moves
• Tighten up check/checkmate methods

Make the game so that the player can play against the computer

• make it so that the computer automatically selects their promotion choice
• Look at why the computer is able to make illegal moves - I seen this happen with the king and pawn, looks like this happens when the king is in check
• The game goes funny wit check/checkmate moves - revisit this once I have solved check/checkmate move

• determine if this is needed
• create methods whereby the king can only move 1 square at a time
• create castling method
• castling is when the king makes 2 moves to the left or two moves to the right, either way the rook will move to the opposing side of the King
• you cannot castle while in check
• castling can only occur when it is the first move for both pieces
• you cannot castle if there are any pieces inbetween the king and the rook

This will need to run on every turn.

• create method to check for checkmate
• create end game method (do you want to restart etc)

When moving the King it can move more than one space at a time anywhere on the board. I believe that this issue will be resolved once I have done the King methods.

I think that I will be able to create a generic method here for some pieces but then more individual specific methods will need to be created for the individual pieces.

• create a loop so that queen, bishop and rook can move x times
• create a method which stops pieces moving if other pieces are in the way

Change the board so that it has a coloured background. This can be done with colorize and .on_red - https://www.devdungeon.com/content/colorize-ruby-terminal-output

• work in en passant - will need to move the class variable into the board instance
• change the welcome message when a game is loaded

While it is a players turn ensure that the current piece they have selected is on constant show. Currently if they make and illegal move it disappears.

Here I could display bot the piece and the location of piece. I could create a new instance variable here if it cannot be done with game_message.

Add a method which alerts that a piece has been taken this should do the following

• Store the taken piece somewhere so that it can be used to display all taken pieces
• Output a message highlighting that a piece has been taken
• I could possibly put a confirmation take piece method in here

A load method needs to be created. This will need to be accessed from the initial load screen and also the main menu during the game.

Within this module I will need to simulate every move. This will be easy for all pieces apart from the King. I think that I can maybe run the legal move method and if the potential_move variable for a piece has something in its array then it is not a stalemate. If all pieces do not contain anything within the potential_move variable then it will be a stale mate. When will I run the stalemate method? I think that I will be able to run this before or after the checkmate method.

Clear the screen and re show the board etc when the player puts the incorrect value in. The screen currently adds text below the existing text and it looks messy.

Pawn moves need to be added to take into account their direction of travel.
Also need to include Pawns being able to move 2 squares for their first move

• determine if this is needed

This will include

• diagonal take move - this is rough as shit and I need to sort it out
• 2 forward on first move
• En passant
• Method for when the pawn reaches the end of the board and can turn into any piece
• need to stop the pawn being able to take pieces moving forward - I think that I should be able to incorporate this into the diagonal method

It should be shown under the chessboard who's turn it is and the current piece which they have selected

• determine if this is needed

The black knight will put the king in checkmate if it makes its way to C2 from the beginning while the left most pawn works its way up.

Add all potential moves for chess pices

Look through all code and refine

A full instruction set needs to be created outlining how the game of chess can be played.

I think that it could be easier to use indexes for a number of methods instead of the co-ordinates, look at how I did this with the pawn_move method. this is a big piece of work but it could help shorten a couple of methods, maybe in the display board module.

Pieces should be shown from what the players have taken from each other

'That is your own piece, please move to another position or restart your turn' shows twice when the code is ran

There is an issue where when I move the knight the whole game freezes but I don't know or what causes the issue - this could be linked to one of the bug I found while creating the computer game mode, I need to try and force this error again to figure out if this is an issue.

I think that this is issue is caused by the loop method when working out the check/checkmate move. The game currently allows you to move the King away from the piece which has it in check, eg. moving it away from the queen
