Okay, so you know how you like to play chess, right? It's a really fun game where you have to use your brain to think ahead and predict the moves of your opponent.
Well, deep blue is a computer that was built specifically to play chess, but it's much smarter than any person could ever be. It can learn and analyze thousands of different chess moves in just a few seconds.
When it plays chess, deep blue looks at all the different moves it could make and tries to predict what its opponent might do next. Then, it picks the best move it can make based on what it thinks its opponent will do.
Deep blue is really famous because back in 1997, it played against the world chess champion, Garry Kasparov, and it actually won! This was a big deal because many people thought that a computer could never beat a human in a game of chess.
Overall, deep blue is an incredibly smart computer that is really good at playing chess. It's taught us a lot about how computers can be programmed to learn and make decisions, and it's still considered one of the greatest accomplishments in the history of artificial intelligence.
