KGS Go Server

A list of the top 100 players,[2] sorted by KGS calculated rank,[3] is regularly updated and maintained.

Kibitzes are common and popular in high-level games, and may include off-topic discussions though this is discouraged by the administrators.

CGoban 3 can also be used as a Smart Game Format (SGF) file editor and viewer.

The players on KGS may be rated, using levels from 30 kyu to 9 dan, according to their results in ranked games.

In October 2015, AlphaGo from DeepMind beat the European Go champion Fan Hui five to zero.
