[Jorge Pichard]

Solving chess means finding an optimal strategy for playing chess, i.e. one by which one of the players (White or Black) can always force a victory, or both can force a draw.

Recent scientific advances have not significantly changed that assessment. The game of checkers was solved in 2007,[5] but it has roughly the square root of the number of positions in chess. Jonathan Schaeffer, the scientist who led the effort, said a breakthrough such as quantum computing would be needed before solving chess could even be attempted, but he does not rule out the possibility, saying that the one thing he learned from his 16-year effort of solving checkers "is to never underestimate the advances in technology".[6] Assuming computational power continues to increase exponentially, chess would be solved "before 2250".[7]
