Setting up a custom position
Does anyone know how to increase the number of squares on which the king moves in castling? I made a 12x8 chess set and for some reason the castling is done like in the original chess, not by four but by two. Can you tell me how to fix this? The position editor has something like a console. Is it possible to use it to fix this problem? Or is the console not that advanced?
