On Panda IGS, there are about 13,000 - 17,000 'completed'games played per
day, and about 100 (1 year = 36,000 games) - 200 (2 years = 72,000) are
professional games. Some of the pro games are available through the
'request' command on Panda IGS.

All players above 8d* are professionals, while most of the 7d* players
are also professional players. All start at 6d. Interestingly, an IGS
9d* = 9p;  all the 9p players end up with 9d* on IGS.
