Artificial intelligence has become so good at chess that its only competition now comes from other computer programs.Indeed, a human hasnt defeated a machine in a chess tournament in 15 years.

Its an impressive technical achievement, but that dominance has also made top-level chess less imaginative, as players now increasingly follow strategies produced by soulless algorithms.

But a newresearch papershows that AI could still make the game better for us puny humans.

The study authors developed a chess enginewith a difference. Unlike most of its predecessors, their system isnt designed to defeat humans. Instead, its programmed to play like them.

The researchers believe Maiacould make the game more fun to play. But it could also help us learn from the computer.

So chess becomes a place where we can try understanding human skill through the lens of super-intelligent AI, said study co-author Jon Kleinberg, a professor at Cornell University.

Their system called Maia is a customized version of AlphaZero, a program developed by research lab DeepMind to master chess, Shogi, and Go.

Instead of building Maia to win a game of chess, the model was trained on individualmoves made by humans. Studyco-author Ashton Anderson said this allowed the system to spot what players should work on:

Maia has algorithmically characterized which mistakes are typical of which levels, and therefore which mistakes people should work on and which mistakes they probably shouldnt, because they are still too difficult.

Maia matched the movesof humans more than 50% of the time, and its accuracy grew as the skill level increases.

The researchers said this prediction accuracy is higher than that of Stockfish, the reigning computer world chess champion.

Maia might not be capable of teaching people to conquer AI at chess but it could help beat their fellow humans.
