Deepmind and Kremnik tapped Alfazero’s ability to learn the game over decades or centuries of human game, quickly discovering new discoveries that would reveal their beauty and flaws. “You don’t want to spend many months or years of your life trying to play something, just to understand, ‘Oh, this isn’t a pretty game.’
Alfazero is the more flexible and powerful successor to Alfago, who set a mark in AI history when he defeated a champion in Goa in 2016. It just starts with learning the rules, the way to score, and the pre-experiment and programmed urge to win. “It’s so bad when it starts to play that I want to hide it under my table,” said Ultric Packett, another deepmind researcher on the project. “But it’s exciting and almost pure to watch it evolve from the void of anything.”
In chess, Alfezero doesn’t initially know he can take the opponent’s pieces. Playing against the ever-more powerful incarnations of the high-speed game for hours, it becomes more sophisticated than the previous chess engine and more natural in some eyes. In the process he rediscovers the centuries-old ideas of human chess and adds his own flair. English Grandmaster Matthew Salder described scattering in Alfazero’s games, such as “finding the secret notebooks of some of the greatest players of the past.”
The nine alternative views of the infection tested by Alfazero include no-castling chess, which Kremnik and others were already thinking about, and had its first dedicated tournament in January. It eliminates a step called castling that allows the player to let their king stand behind the other pieces – the powerful fortified protective screen – which can also be boring. The five variants modified the movement of pawns, including torpedo chess, in which pawns could go up to two squares at a time during the game, instead of just their first move.
One way to read the results of Alphazero is in cold numbers. Draws under no-castling chess were less common than conventional rules. And learning different rules shifted the value of the Alfiziro held on different pieces: under the traditional rules the value of that queen was 9.5 pawns; Under the torpedo rules the Queen’s price was only 7.1 pawns.
Deepmind’s researchers eventually became more interested in the analysis of another chess brain on the project, Kremnik. “It’s not about numbers, but whether it’s qualitative or not, it’s fun to sit and play with aesthetic men,” says Tomayev. The technical paper, released Wednesday, includes more than 70 pages of comments made by Kremnik on Alfazero’s research.
Kremnik saw a glimmer of beauty in the way Alfazero adapted to the new rules. No-castling chess was provoking rich new ways to keep the king safe, he says. A more extreme transformation, the self-capture chess, in which a player can take his own pieces, proved even more exciting. This rule gives the player more opportunities to effectively sacrifice the piece to move forward, a trick that has been the hallmark of the game for centuries, says Kramnick. “All of this makes the game more beautiful,” he says.
Kremnik hopes that Alfazero’s adventures in alien forms of chess will persuade players of all levels to try. “It’s our gift to the world of chess,” he says. Now may be the technology moment.
Chess has been gaining popularity over the years, but the epidemic has gained momentum as many people seek new intellectual stimuli, the two-time U.S. woman said. Says chess champion Jennifer Shahde. Interest in Chess 960 has also grown, indicating an appetite for a new type of game, including some superstars. This weekend, Shahdeh will make comments for the Chess 960 tournament, including world number one Magnus Carlsen and former champion Kasparov.
Like Kremnik, Shahd also saw a variety of things to choose from in the different types tested by Alfazero, even though changes such as allowing pawns to move sideways felt “mindbending.” If there is any gain traction, some players will still want to lean on computer and deep research to move forward, but resetting the cycle can be interesting to watch. U.S. “These findings will be refreshing – they can be very exciting and can benefit a wide variety of players,” says Eva Shahde, director of women’s programs at the Chess Federation.
