The Polish Immortal was a famous game between Glinksberg and Miguel Najdorf played in Warsaw. Some sources give its date 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 Nadjorf's opponent as "Glinksberg", attributing these facts to Nadjorf and his daughter. In this game Black sacrificed all four of his minor pieces.
