Exception when starting a new game

@timwoelfle

It appears that one of the three recent commits have broken the game. Getting the following exception when starting a new offline game:

Bug: It is possible to put yourself into checkmate

This should be self explanatory

https://i.imgur.com/d8qbGLe.png

White moved the horse away from shielding the king from the opponent rook and thus put White into check. The game failed to prevent this move being made and did not show the 'check' flashing at any point. Black is unable to actually take the White King with its rook. Black then informs me they did actually move, trying to take the King with their rook and now sees this

My (White) view of the board remains the same and I cannot see the update, still seeing it as black's turn even after reloading the page in a new tab.

Trying to get in touch regarding a security issue

Hey there!

I'd like to report a security issue but cannot find contact instructions on your repository.

If not a hassle, might you kindly add a SECURITY.md file with an email, or another contact method? GitHub recommends this best practice to ensure security issues are responsibly disclosed, and it would serve as a simple instruction for security researchers in the future.

Thank you for your consideration, and I look forward to hearing from you!

Castling broke the game

Castling the king with the rook made the opponent's queen take the rook. The game doesn't function after this move because the player can no longer move. In the attached image you can see that the queen is in an impossible position in the right bottom corner of the board.

Bug Found - Disappearing Piece

About half way through a game (in which I was winning ;) one of my pieces disappeared off the board when I clicked on it to make a move. I could see the piece on the right hand side and it was sort of greyed out.

The piece never came back but I could continue with my move using a different piece.

I have no idea what happened.

Issue screenshot

Bug Found - Could not move rook into a check position

In the same game where one of my pieces disappeared off the board (created a separate issue for this), I could not move my rook to the right to put my opponent into check. The same thing happened when I had the option for check-mate.

I could move the rook up and left, but not right or down.

Thank you for the chess!

missing games folder

Your code requires a games folder be created and writeable. You should include this with your code here, or at least create a readme file explaining such.

Bug when there are 2 checks going on at the same time

I was playing a game with my friend yesterday and noticed that in this position that we had (check the video attached), I was allowed to move my (white) knight on e2 to g1 to block the check from the black Queen on h1, but that's an illegal move because the white knight was pinned by the black Bishop on f3 to the white King, so I shouldn't have been allowed to move it. Therefore, I propose that some changes are made to this game so that this doesn't happen.

Let me know if this makes sense.

Thanks!

Bug with King not being able to move to a valid square

In this position, Black wants to move to Kf8, but on the website, it's not allowed, however it is a valid move in the game.

Bug with timeout

First of all - awesome game. This is exactly what me and my friends were hunting for. We play it for like 3 hours a day in class. It's great.

Oftentimes once the game has been in play for >10 minutes, it shuts off. On both players screens it says 'Opponent's turn'. I know you've made the game using sockets - but is there something wrong? Could it be our WiFi?

Refreshing doesn't work.

Upgradation

Hello,

        Application was awesome !! Can we make this finding host automatic system.

Castle

I tried moving the king and tried moving the rook to castle, but nothing happens. Does the game's code allow for it?

Managed to capture opponents king

King was on the 1st rank. King was threatened by a check by a rook. White moved knight to stop the check which was an illegal move as the knight already guarded the king from check by bishop. After the illegal knight move bishop captured the king to try whether it works and indeed it did.

Move validation on server side

It is incredibly easy as is to falsify moves and move your pieces anywhere on the board.

Example:
startColumn=5&startRow=8&endColumn=1&endRow=1
