RE: [computer-go] Computer Go hardware

Go programs do use computer chess techniques :)  They all do
alpha-beta search.  Most have transposition tables.  The problem is
the huge branching factor and the complexity of the evaluation function,
so heuristics/ANN/patterns are needed for move sorting and pruning, and
the evaluation function is full of heuristics.

I started with 16 MHz 80286, so I fully appreciate the benefit of 1000x
more CPU power.
