It's tough.  There are too many patterns.  In the opening, groups are
difficult to evaluate for safety, since there is nothing like surrounded
eyes in a 3-space extension.  Many positions can be cut if you read them,
but in practice are never cut since that leads to a poor position.  Many
faces depends on opening knowledge of good moves because its group
evaluation is poor in the opening.

Also, is it just me that a good evaluation function early in the game is
difficult to write? 
 


I think it's doable.  It's just not trivial.  Simple pattern matching should
give a reasonable approximation for corner spats at the start of the game.
Feeding group safety into an overall evaluation should be able to give
tenuki plays.  Books on opening theory seem relatively straightforward. 

I've neither coded it into my bot or mastered it in my play...  So it could
be tougher than I think it is ;)
