Chess on Yahoo! Games is a popular aspect of Yahoo! Games. It allows users to play rated or unrated chess, including tournaments, leagues, and ladders. Yahoo! Games can be accessed for chess using a Java enabled browser. Efforts to emulate chess servers are in development through YICS, wherein Yahoo! Games may be accessed through a standard FICS-style chess client.[1] Yahoo! Games is currently one of the large online sites where chess players meet, but has been criticized for its rating and computer abuse, spammers, failure to implement the Portable Game Notation standard, (actually PGN has been implemented on Yahoo!, though it is easy to overlook). and awkward structure.
