UPDATE:
How to reproduce:

• Make breakpoint on line 32.
• Click twice on random white piece.
• Run the following code in the console:

var fromArray=[{x:1,y:7},{x:7,y:1},{x:5,y:6},{x:7,y:3},{x:2,y:5},{x:7,y:4},{x:4,y:4},{x:7,y:5},{x:5,y:7},{x:7,y:0},{x:7,y:7},{x:6,y:1},{x:5,y:6},{x:6,y:3},{x:5,y:5},{x:5,y:1},{x:6,y:4},{x:4,y:1},{x:4,y:4},{x:3,y:0},{x:3,y:6},{x:6,y:3},{x:3,y:7},{x:4,y:3},{x:4,y:6},{x:3,y:4},{x:4,y:7},{x:3,y:1},{x:4,y:6},{x:2,y:0},{x:4,y:5},{x:5,y:3},{x:3,y:4},{x:2,y:6},{x:3,y:3},{x:7,y:1},{x:4,y:3},{x:1,y:7},{x:0,y:7},{x:2,y:1},{x:1,y:6},{x:2,y:3},{x:1,y:5},{x:1,y:1},{x:2,y:4},{x:0,y:1},{x:1,y:3},{x:1,y:0},{x:0,y:6},{x:0,y:0},{x:2,y:7},{x:0,y:2}]
var toArray=[{x:2,y:5},{x:7,y:3},{x:5,y:5},{x:7,y:4},{x:4,y:4},{x:7,y:5},{x:5,y:6},{x:6,y:6},{x:6,y:6},{x:7,y:6},{x:7,y:6},{x:6,y:3},{x:4,y:4},{x:6,y:4},{x:6,y:4},{x:5,y:3},{x:5,y:3},{x:4,y:3},{x:6,y:3},{x:6,y:3},{x:3,y:4},{x:2,y:7},{x:2,y:7},{x:3,y:4},{x:4,y:5},{x:4,y:5},{x:4,y:6},{x:3,y:3},{x:4,y:5},{x:5,y:3},{x:3,y:4},{x:2,y:6},{x:3,y:3},{x:7,y:1},{x:4,y:3},{x:1,y:7},{x:5,y:4},{x:0,y:6},{x:0,y:6},{x:2,y:3},{x:1,y:5},{x:2,y:4},{x:2,y:4},{x:1,y:3},{x:1,y:3},{x:0,y:3},{x:0,y:2},{x:0,y:2},{x:0,y:2},{x:0,y:2},{x:2,y:4},{x:0,y:0}]
fromArray.map((ev,i)=>{this.moveSelected(this.board[ev.y][ev.x],toArray[i],()=>{},()=>{},!1,!1,!1)})

• Move Qc6

Add the Fifty move rule

• AI can control the white figures;
• AI can't promote pawns;

Add the threefold repetition rule to the game.

The algorithm in the new AI is powerful, but if you run it with depth bigger than 3, the UI will freeze for seconds and the mobile version will even crash.
At the moment we're using WebViews from PhoneGap and Electron to make RSG Chess multi-platform, so the problem can be fixed on all platforms using Web Workers. Docs and tutorials can be find on MDN and some really helpful blog posts.

Add FEN notation support.
This feature will be helpful:

• in RSG Chess APIs (The API will be more customizable and comfortable);
• in AI algorithm #3;
• when checking for the threefold repetition (#5);
• when checking for the fifty-move rule #6;

Needed fields:

• Piece placement;
• Active colour;
• Castling availability;
• En passant;
• Halfmove clock;
• Fullmove number;

Additional to-dos:

• Separate the functions for more customizable API, more beautiful code and better performance.
• Remove the useless FEN fields and move them to the Chess APIs - #7 (comment)

A white pawn was promoted to a Queen, when the black King was on h8. The game continued with a random move instead of realizing the King is in check by the promotion.
Then i removed the black King with my Queen and the game continued. :D

Good luck!
