Polish Immortal

Polish Immortal is the name given to a chess game between Glucksberg and Miguel Najdorf played in Warsaw. The game is celebrated because of Black's sacrifice of all four of his.

Some sources give the date of this game as 1930 or 1935, and give the name of the player of the white pieces as "Glucksberg". Garry Kasparov gives the date of the game as 1928, and the name of Najdorf's opponent as "Glinksberg", attributing these facts to Najdorf and his daughter.
