Chess engine

A chess engine is like a smart person who is really good at playing chess.

Just like a smart person, the chess engine knows all the rules of chess and can make smart moves based on what it knows.

But the chess engine doesn't just use its brain to play chess. It uses a computer program that helps it think even faster and make even better moves.

The computer program is like a big calculator that can think really quickly and analyze all the different possibilities for each move.

So when you play against a chess engine, it's like playing against a really smart and really fast calculator that knows all the rules of chess.
