Anderssen is famous today for his brilliant sacrificial attacking play, particularly in the "Immortal Game" (1851) and the "Evergreen Game" (1852). He was an important figure in the development of chess problems, driving forward the transition from the "Old School" of problem composition to the elegance and complexity of modern compositions. He was also one of the most likeable of chess masters and became an "elder statesman" of the game, to whom others turned for advice or arbitration.
