The romantic era of chess is a period from around 1850 to 1950. In this period, chess players mainly relied on tactics, wild sacrifices and extremely dynamic play. One of the most famous games from the romantic era of chess is the game between Adolf Anderssen and Lionel Kieseritzky. It was played in London in 1851. Nowadays, it is known as the "Immortal Game". Anderssen gave up almost all his pieces to checkmate his opponent.
