AJUKO

To find out what it consists of, all you have to do is download any of the applications NUMERICAL CHESS or NUMERICAL CHESS 2 for free.

You also have a free PDF that you can download on the Facebook page titled NUMERICAL CHESS.

It basically consists of representing with numbers the legal moves that a chess figure has at a given moment of the game. For castling, a move is added to the king whether he castles for one side or for both, and this number is only added if he can castle at that moment, whether it is his turn or not. In the same way, a move is added to the rook with which he can castle or both if he can do it both long and short.

The check has its rules somewhat longer to explain but they all come to you in the application.

Checkmate and draw cannot be represented as the game is already over and there are no legal moves.

The application is free and now it has little advertising that I will remove completely later as I have to pay for it.
