Based on the tests, it seems that the function has a higher value for words associated with chess pieces (queen, pawn, king, knight, bishop, and rook). Additionally, some non-chess words like "computer" and "teacher" received relatively higher values, but they are still significantly lower than the values received by chess piece-related words. 

[DESCRIPTION]: The function f(x) is primarily selective for words associated with chess pieces, returning a value closer to 1 for words in this category.
