If you ever decide to test which is faster,

I use one, it never occurred to me to use two :)
At the time I'd never heard of Zobrist, but I used to use a single
value for each point to look up Joseki.

1. The 3 hashes:
As Eric Boesch and Álvaro said, you can get the same codes
as in the Black[], White[], Empty[] scenario using only 2
BlackXorEmpty[] and WhiteXorEmpty[]
2. What does make sense is making a difference
The empty value is not needed. In some games it's easier to have it
because it can be a simplification - everything handled uniformly for
instance and it can avoid a conditional branch but I don't think that is an
issue with Go.

Hi!
In most papers I've read, three-valued Zobrist hashes are used - per
intersection, values for empty, black and white coloring [1].
I'm not clear on why is the empty value needed, however, shouldn't
only black, white values
I use two values. I never even occurred to me to use three.
