I always thought it odd that the assigned values of chess pieces are integers.
Given the complexity of the game that can't really be true, can it?
And indeed it isn't. A short thread ๐งต 1/7

The source for integer values is apparantly the popular book by Reuben Fine which popularized the 1-3-3-5-9 values in 1942

But there have been several people working through pages of maths to come to more fine-grained scales. Here is a summary from 1916

This sounds like a hard problem, because values of chess pieces depend on the other pieces left on the board. For example a bishop is worth much more if you still have the other bishop. In fact that this separation was later made by several people

The result is still remarkably well approximated by the integer values, although AlphaZero finds rooks and queen to be worth closer to 6 and 10

The same approach was used for different rule settings. Interestingly even significant rule changes don't change the relative values much.
