World Chess Classic

The World Chess Classic (WCCA) is an annually held, FIDE-recognized, international Chess tournament since 2000 to determine the "Classic" Chess champion.
== Sponsor ==
PricewaterhouseCoopers sponsored the World Chess Classic tournaments from 2000 to 2004. After the five-year contract expired in 2005, International Business Machines Corporation (IBM) stepped in as the primary sponsor of the World Chess Classic from 2005 to 2009. In 2010, PepsiCo, Inc. agreed to sponsor the WCCA for the next 5 years, until 2014. From 2015 to 2019, Red Bull acted as the title sponsor for the WCCA, and in 2020, McDonalds agreed to be the primary sponsor until 2024.
== WCCA Rating System ==
The World Chess Classic introduced a rating list for its participants in 2010. It remained unrecognized by FIDE until 2014, when they agreed to use it as an alternative rating system for official chess tournaments partly organized by FIDE.
