Exploring chess engines

Most chess engines will start by generating a list of all legal moves in the current position. It will then examine each of these moves one-by-one. It will perform the move on the board and then evaluate the resulting new position

This is called brute-force search, because all legal moves are considered. This is very different from how a human thinks. Humans typically only consider a few candidate moves
