How do computers play chess so well?

Computers play chess so well by combining brute-force calculation (searching millions of moves ahead) with sophisticated neural networks and machine learning, allowing them to evaluate positions deeply, learn from vast databases of games, and identify complex patterns far beyond human capability, all while remaining unemotional and tactical. Modern engines use massive search algorithms (like Alpha-Beta pruning) to explore move trees and evaluation functions trained on games to assess board states, making them virtually unbeatable.

The "stupidest" rule in chess, according to many players, is stalemate, where a player with no legal moves, but not in check, results in an immediate draw, often snatching victory from a dominant player by accident, which feels anticlimactic and counterintuitive to winning.
