WTCC meaning in General ?

The World Team Chess Championship is an international team chess event, eligible for the participation of 10 countries whose chess federations dominate their continent. It is played every two years. In chess, this tournament and the Chess Olympiads are the most important international tournaments for teams.

The strongest national teams in the world participate, and also some teams representing a continent. A full round is played by the teams, meaning that each team plays against every other team. At the first tournament, in 1985, teams consisted of six players, since then of four players. Reserve players are permitted.

From 1985 the championship was held every four years, since 2011 every two years. Since 2007 there is a separate championship for women teams, which is also held every two years.
Since 2007 the final scores depend on the team results, before 2007 the individual scores determined the final ranking.
