  Game playing programs have been used since the 1950s to demonstrate and test AI's most advanced 
  techniques.[145] Deep Blue became the first computer chess-playing system to beat a reigning world chess 
  champion, Garry Kasparov, on 11 May 1997.[146] In 2011, in a*Jeopardy!*quiz show exhibition match, 
  IBM's question answering system, Watson, defeated the two greatest*Jeopardy!*champions, Brad Rutter 
  and Ken Jennings, by a significant margin.[147] In March 2016, AlphaGo won 4 out of 5 games of Go in a 
  match with Go champion Lee Sedol, becoming the first computer Go-playing system to beat a 
  professional Go player without handicaps. Then, in 2017, it defeated Ke Jie, who was the best Go player 
  in the world.[148] Other programs handle imperfect-information games, such as the poker-playing 
  program Pluribus.[149] DeepMind developed increasingly generalistic reinforcement learning models, 
  such as with MuZero, which could be trained to play chess, Go, or Atari games.[150] In 2019, DeepMind's 
  AlphaStar achieved grandmaster level in StarCraft II, a particularly challenging real-time strategy game 
  that involves incomplete knowledge of what happens on the map.[151] In 2021, an AI agent competed in a 
  PlayStation Gran Turismo competition, winning against four of the world's best Gran Turismo drivers 
  using deep reinforcement learning.[152] In 2024, Google DeepMind introduced SIMA, a type of AI 
  capable of autonomously playing nine previously unseen open-world video games by observing screen 
  output, as well as executing short, specific tasks in response to natural language instructions.[153]
