Here’s why it’s so huge: In an average position, a player has about 20 possible moves. A typical chess game lasts around 40 moves per player (80 moves total). So the number of different possible games is roughly: 20⁸⁰ ≈ 10¹²⁰ possible games To compare: Estimated number of atoms in the observable universe ≈ 10⁸⁰ Possible chess games ≈ 10¹²⁰ That means: If every atom in the universe was a computer playing chess games non-stop, it still wouldn’t be able to play every possible game. So even though chess has simple rules and a small board, its complexity is bigger than the universe itself in terms of possibilities. That’s why: Chess engines can’t brute-force all games They use strategy, evaluation, and pruning instead of trying everything"
