The rule says that the a1 (and consequently the h8) square must be black, in other words, the leftmost square of the first row of each player must be black. With this the kings stay at the right side of the players at the initial position.
I was wondering if there are any significant changes in the game if we start it by reflecting the official initial position. With this the a1 and h8 squares would be white and the kings would stay at the left side of the players.
My thoughts are that there won't be any significant changes, because there is a bijection between all the positions with the two initial positions. In other words, for each position with respect to the official initial position there is an equivalent position with respect to the new initial position (we just have to reflect the board), and vice versa.
What you guys think of it?
