There's no particular need to do anything drastic with the existing
code. The only thing that matters in the short term for making GNU Go
stronger is to catch up with the Monte Carlo development, especially
make the Monte Carlo code scale better to larger boards. Key ideas to
look into there are RAVE (rapid action value estimation),
progressive widening, and improved move ordering.
