Been watching some more videos.
The world chess championship (human division) is underway right now between the top 2 human players in the world. So far they've played 8 games and they've all ended in draws. This is the 8th game:
The American player, Caruana, missed a good move in the middle that might have led to a victory.
Watching this video made me realize how much human chessplay is now influenced by AI chessplay. The best chess players in the world are now computer programs, and even the best human player would likely lose to any of them. But they can use these programs to practice, hone their skills, and even probably get ideas from. They can go back to their past games and analyze any position with an algorithm and see what the computer would have done, and, if their memory is good, remember it for the future. Sometimes the value of a particular move doesn't become apparent until a few moves later.
Anyway, this guy seems to be pretty good at analyzing the various positions.
Here's his analysis of a match between two computer programs, both of which are rated higher than the highest rated human player:
Leela Chess Zero demolishes her opponent here. She has some cool avatars you can search for.
Leela Chess Zero is a free and open-source chess engine and distributed computing project. Development has been spearheaded by programmer Gary Linscott, who is also a developer for the Stockfish chess engine. Leela Chess Zero was adapted from the Leela Zero Go engine, which in turn was based on Google's AlphaGo Zero project, also to verify the methods in the AlphaZero paper as applied to the game of chess.
Like Leela Zero and AlphaGo Zero, Leela Chess Zero only knows the basic rules and nothing more. Leela Chess Zero is trained by a distributed computing network coordinated at the Leela Chess Zero website. As of August 2018, it had trained itself by playing over 23 million games of chess against itself.
I think there's a difference between a "chess engine" like Stockfish and an "AI" like Leela Chess Zero. But that's sort of beyond me to explain better than Wikipedia can. The latter seem to have surpassed the former though.
Here's another youtuber talking about her:
A fool thinks himself to be wise, but a wise man knows himself to be a fool.
