[computer-go] Elo and handicap matching

[Don Dailey]

The only issue is that I don't know if GnuGo is representative of 19x19
to 9x9 go strength.   I am interested in knowing how a human 19x19
scales down to 9x9 play.      It's well known that programs scale up poorly.

However, this data should still be quite useful.
