Sometimes we hear that in chess, who starts with White Pieces has an advantage\u2026 but why? I am not an expert in chess, but I know how to play enough to deal with this matter from a mathematical point of view. However, we will start this discussion with a much simpler game, but that uses the same argument that we will make in the case of chess: the tic-tac-toe game.<\/p>

I imagine that most adults would consider this a rather trivial game. Altogether there are 9! plays, that is, 362.880 ways to complete the 9 squares. But if we ignore symmetrical moves, rotations and reflections, we have only 138 ways to complete the 9 squares.<\/p>

We know however that there is no winning move, so there is no way to win if both players are smart enough (the game will always end in a draw). But if by chance there was an initial move that would lead the 1st player to win definitively. In this case, the 1st player could always take it and using this same strategy he would win all the matches. What if there was an initial move that led the 2nd player to win definitively? In this case, the 1st player would simply not choose this initial play, as he knows that this will make him lose to the 2nd player. Thus preferring to choose for a tie. Simple reasoning?<\/p>

Now let’s go to chess … remember that the analytical complexity of chess is gigantic, even though there is still no well-defined strategy to guarantee a player victory, we can guarantee that there are only 20 possible initial moves for the White Pieces (16 movements with pawns and 4 movements with knights).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

So, if both players knew all the possible chess moves, when one of them moves the first piece, both would know immediately if the game will end with the victory for the White Pieces, for the Black Pieces or tied.<\/p>

So, of those 20 initial plays, it is enough that there is only one that takes the White Pieces to victory, because the White Pieces start. Likewise, if there is no initial move that leads White Pieces to victory, the player can choose an initial move that guarantees a draw. In this case, the Black Pieces will only win if all 20 initial moves lead to the Black Pieces winning.<\/p>

As I said earlier, the analytical complexity of chess cannot be treated computationally by current strategies and resources. In this way, any well-defined strategy is unknown.<\/p>

But this means that when well-defined chess strategies are discovered, if one ends in victory for the White Pieces, the Black Pieces player will be doomed to lose forever. Even if a well-defined chess strategy is discovered that wins the Black Pieces, the White Pieces player can simply start with one of the other 19 starting moves.<\/p>

In this way, the Black Pieces suffer much more in this game, and will continue to suffer until all 20 well-defined chess strategies are discovered, and none of them determines a victory for the White Pieces or tied.<\/p>

I sincerely hope that all well-defined chess strategies will result in victory for the Black Pieces, because in this way, even though 19 of these strategies have already been discovered, we could play with the twentieth start whose result is not yet known.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
