Quick and simple development leading to a direct attack: that was Morphy's method. His openings were first-rate for their time. He brought off some outstanding combinations and sacrifices, and his best games are still a model for young players. His games mark the high point of the romantic movement in chess, where players would play all out for direct attacks. This style was later squashed by better defensive technique, especially for the black side in the openings. Out of this came Dr Tarrasch's classical principles, and the idea that no game can be lost without a mistake being made. The chess of the 1890s came to look quite different from Morphy's games, partly because he had forced players to think more clearly about what they were doing.
