The World Chess Solving Championship (WCSC) is an annual competition in the solving of chess problems organised by the World Federation for Chess Composition (WFCC), previously by FIDE via the Permanent Commission of the FIDE for Chess Compositions (PCCC).
The participants must solve a series of different types of chess problem in a certain length of time. Points are awarded for correct solutions in the least amount of time. The lowest score at the end of the competition is proclaimed the winner.
The Tournament consists of six rounds over two days, with three rounds each day according to the following table:
Round 1 - 3 twomovers 20 minutes solving time
Round 2 - 3 threemovers 60 minutes solving time
Round 3 - 3 endgame studies 100 minutes solving time
Round 4 - 3 helpmates 50 minutes solving time
Round 5 - 3 moremovers 80 minutes solving time
Round 6 - 3 selfmates 50 minutes solving time
Team Championship - To qualify as an official team world championship, there must be at least seven teams from seven different countries present. This section has grown from nine teams in 1977 to now averaging 20.
Individual - Likewise, for an official individual world championship to take place, 30 solvers from at least 10 countries must participate. This number too has grown from 18 in 1977 to well over 70 in the past six years (as of 2007).
Women and Juniors (up to 23 years old) - This event only requires 10 solvers from at least seven countries.
For calculating a players rating whom previously did not have a rating, a provisional rating is given. This rating is given at the completion of the player's first tournament where the formula used is as follows:
Provisional Rating = (Average Tournament Player's Rating) x (Player's Result / Average Result At Tournament)
For players who have previously established a rating the following formula demonstrates how a new rating is achieved.
New Rating = (Old Rating) + (KT) x (Player's Result - (Average Result x Old Rating / Average Tournament Old Rating))
KT = Tournament Coefficient (Ranging from 4 to 1 depending on strength of competition)
