What it is

A computerized database of precalculated evaluations for every legal position in a chess endgame with few pieces, first generated by Ken Thompson at Bell Labs in the late 1970s and later popularized by the Nalimov tablebases.

What it led to

  • The Nalimov tablebases (1998), a standard format in chess engines
  • Complete solving of endgames with up to seven pieces (the Lomonosov project)
  • Use in analysis and training by elite chess players
