[computer-go] 50, 576 pro/dan games without repetitions nor easilydetectable problems

[David Fotland]

Did you get the 40K IGS amateur games off the MFGO CD?  The installer leaves
them on the CD, but I included them for researchers like you.  I pulled them
off IGS many years ago when the game records were still available.
