Chess is a game of infinite possibilities..
After only 40 moves in a chess game.. the number of possible scenarios becomes greater than the number of atoms in the visible universe Scientists estimate that the number of atoms in the universe is about 10^80.. but the number of possibilities for playing chess exceeds 10^120.. which is a number that is too large to be calculated even by the most powerful supercomputers.. This makes it mathematically impossible to predict all possible moves..
This is why chess remains a complex game even for the most powerful artificial intelligence.
Note.....!!
Chess is a game limited in moves and each piece has a limited number of branches, which makes the huge numbers about the possibilities of moves exaggerated Many theoretical estimates such as the possibilities exceeding the number of atoms in the universe are not accurate because most of the possible moves are wrong or illogical In reality, even computers do not calculate all the possibilities but focus only on the best moves to achieve victory..
