Probably many were tried and the most popular became the standard.
But I don't know, I'm interested to hear the specifics also.
With a modern understanding, the knight position makes sense. It's flexible (can move to 2 different squares), neither square blocks the center, and on c3 f3 they influence all 4 central squares. Even if you didn't value the center, this lets them hit about any square on the board in 3 moves or less.
Bishops make some sense too. Yeah long diagonals are important, but I think it's reasonable to not want them attacking the enemy after just 1 move, which makes the game less complex (with a bishop on a1 or b1, once you move a pawn and you attack). Also bishops are impotent to squares in front of them. So if placed on e1 or d1 they are more awkward to bring into the game.
Rooks aren't very effective pieces while each side still has 8 pawns, so stuffing them in the corners keeps them out of the way until some trades have happened.
I don't know why the queen and king are in the middle. Process of elimination after placing all the others I guess.
Those are my thoughts. Early experimenters couldn't have thought of all that, but the fluidity of development and complexity of strategy I'm sure led them to this arrangement (and many other rules like castling and stalemate as a draw).
I was interested to know how the pieces on a chess board are arranged in the way that they are, does anybody know the reason for this?
The first idea that comes to my mind is symmetry, it's manifested in nature itself. But if you were to switch the knights and bishops around the symmetry is still preserved.
Obviously there is still Chess 960 to consider, but what makes the standard chess set-up so unique as opposed towards any other method?
At some point on our time line, there would have had to been numerous discussions and decisions about this, followed by rules, in order to get the game to where it is today.
