To weakly solve a game is to prove the result from the starting position assuming perfect play by both sides. For checkers that proven result is a draw.
Is checkers solved?
Quick answer: Yes, standard 8x8 checkers was weakly solved in 2007 by the Chinook team led by Jonathan Schaeffer, and the result is that a perfectly played game ends in a draw.
Checkers holds a special place in game history as one of the most complex games ever solved by computer.
What solved means
The Chinook project
A team at the University of Alberta led by Jonathan Schaeffer built the Chinook program and, after nearly two decades of computation, announced the solution in 2007. It remains a landmark achievement in artificial intelligence.
What it means for players
The solution does not spoil the fun. No human can memorize the full result, so games between people are still a genuine contest of skill.
