The document summarizes the history of chess from the 1600s to 1851. It describes how Greco established an attacking style in the 1600s. Philidor was the first to develop actual strategies in the 1700s. In the early 1800s, La Bourdonnais and McDonnell emerged as the strongest players, with La Bourdonnais winning a match between them. After their deaths, Saint-Amant and Staunton played a match in 1843, which Staunton won to become recognized as the strongest player. Staunton then organized the first international chess tournament in 1851, which was won by Adolf Anderssen in an upset over Staunton.
