Shortly after the 1851 London International Tournament, Anderssen played his two most famous games, both casual encounters which he won by combinations that involved several sacrifices. In the first, as White against Lionel Kieseritzky in London just after the International Tournament (1851) and now called the "Immortal Game", he sacrificed a bishop, both rooks and finally his queen. In the second, played in Berlin in 1852 as White against Jean Dufresne and now called the "Evergreen Game", the total sacrifice was more modest, but still exceeded a queen and a minor piece.
