pixel_player962541975 I am proof that one DOESN'T need to have ANY knowledge of chess to figure out this board☺
The clues are to move the pieces according to the signs on the outskirts of the board that give you the coordinates. Then simply look at the signs surrounding the board for the corresponding numbers/letters.
In case the above makes absolutely no sense to you, here's the solution. Sorry the board got cut off, no way to zoom out on mobile.
