Can I Play Agains Alpha Zero
In 2017 the chess world was shaken to its cadre when Stockfish (the world's strongest chess engine) was defeated in a one-sided match. Information technology was non defeated by a human but by an unknown estimator programme that seemed to be otherworldly—AlphaZero.
Allow's acquire more than almost this powerful chess entity. Here is what you need to know nigh AlphaZero:

What Is AlphaZero?
AlphaZero was developed by the artificial intelligence and research visitor DeepMind, which was acquired by Google. It is a computer plan that reached a nearly unthinkable level of play using only reinforcement learning and self-play in gild to train its neural networks. In other words, it was only given the rules of the game then played against itself many millions of times (44 million games in the showtime nine hours, co-ordinate to DeepMind).
AlphaZero uses its neural networks to brand extremely advanced evaluations of positions, which negates the need to look at over 70 million positions per second (similar Stockfish does). According to DeepMind, AlphaZero reached the benchmarks necessary to defeat Stockfish in a mere four hours.
AlphaZero runs on custom hardware that some take referred to every bit a "Google Supercomputer"—although DeepMind has since clarified that AlphaZero ran on four tensor processing units (TPUs) in its matches.
In December 2017, DeepMind published a inquiry paper that announced that AlphaZero had easily defeated Stockfish in a 100-game lucifer. AlphaZero would go on to defeat Stockfish in a second friction match consisting of ane,000 games; the results were published in a paper in late 2018.
Unfortunately, AlphaZero is non bachelor to the public in any form. The match results versus Stockfish and AlphaZero's incredible games accept led to multiple open-source neural network chess projects being created. Leela Chess Zippo, Leelenstein, Alliestein, and others try to emulate AlphaZero'southward learning and playing style. Even Stockfish, the conventional brute-force king, has added neural networks.
In 2020 DeepMind and AlphaZero continued to contribute to the chess world in the form of dissimilar chess variants. When DeepMind and the AlphaZero team speak, the chess world listens!
From the moment it stepped onto the scene, AlphaZero has inverse chess by spawning a new generation of neural network chess engines, by contributing to chess variants, and through its transcendent games.
AlphaZero's Accomplishments
As mentioned, AlphaZero defeated the world'south strongest chess engine, Stockfish, in a i-sided 100-game match in December 2017 (scoring 28 wins, 72 draws, and nil losses). The public was given 10 example games from this match, and the chess world's reaction was borderline disbelief. GM Peter Heine Nielsen likened watching AlphaZero's games to seeing a superior species landing on earth and showing us how to play chess:
Other grandmasters shared Nielsen's sentiment, including the legendary GM Garry Kasparov, who told Chess.com, "Information technology's a remarkable achievement.... It approaches the 'Type B,' human-like approach to machine chess dreamt of by Claude Shannon and Alan Turing instead of fauna strength."
Others questioned the results considering of the disparity of hardware used in the first match. Some also found information technology unfair that Stockfish was not allowed to use its opening book and its endgame tablebase.
GM Hikaru Nakamura stated: "I don't necessarily put a lot of brownie in the results but because my understanding is that AlphaZero is basically using the Google supercomputer, and Stockfish doesn't run on that hardware; Stockfish was basically running on what would be my laptop."
Roughly one yr afterwards the start match, DeepMind published a new newspaper that announced an updated version of AlphaZero had defeated Stockfish in a 1,000-game match. This time, the electric current version of Stockfish (version 9 at the time) was used, Stockfish was able to use a strong opening book in many of the games, the time controls were adjusted (with Stockfish having large time advantages), and Stockfish was run on the same type of hardware used in the Top Chess Engine Championships (TCEC).
The results didn't change much—AlphaZero defeated Stockfish over again with a score of 155 wins, 839 draws, and 6 losses.
AlphaZero And Chess Variants
In 2019 and 2020 GM Vladimir Kramnik was able to spend some fourth dimension with AlphaZero and the DeepMind team to explore chess variants and co-wrote a newspaper with DeepMind nearly the exploration of new chess variants, including sideways pawns, no castling, torpedo chess (where pawns tin can always motility forwards one or more squares).
In September 2020 Chess.com hosted a roundtable discussion with Kramnik and members of the DeepMind team where they discussed variants and other topics. You can watch the full video here:
Many of these chess variants (and more) take been added to Chess.com. This article outlines the new chess variants and how to play them. If you lot want to check out any of these variants for yourself, simply caput over to Chess.com/variants or hover your mouse over the "Play" push button in the menu bar and select "Variants":
After you lot select "Variants," you are directed to the Chess Variants Page. All y'all have to exercise is select a variant and press "Play."
AlphaZero Games
In this first game example, we see some of the magic that AlphaZero shocked the earth with in the showtime match. AlphaZero gambits a pawn in the opening and immediately goes on the attack. After 19...Kxh6 Stockfish is upwardly a piece, but the rex is not prophylactic, and the entire queenside is undeveloped:
AlphaZero keeps upward the pressure, just its compensation for the piece is mostly unclear to us mortals. Only in retrospect can we tell that a couple of Black's pieces (near notably the a8-rook and queen'south knight) volition never actually exist part of the game. After 36.Qe6, the position has crystallized, and AlphaZero wins assuredly:
This second game case is from the second AlphaZero-Stockfish match. AlphaZero puts on a positional clinic and tortures Stockfish with the bishop pair in the endgame after 45. Bxe4. Here is the full game:
In the following video, GM Robert Hess covers this fantastic game in great item:
