Tournament Information
The 2010 World Championship, the 7th annual championship, will begin on Thursday, 7 January 2010 and continue for approximately 12 weeks (depending upon whether byes or a third place game are necessary). Similar to the previous two World Championships, there will an Open Classic Swiss System tournament to determine the top eight finalists for the double-elimination knockout World Championship Finals. Games will continue thereafter until one survivor remains. Open Classic games will use a time control of 60s/5m/75/0/4h/4m with an extra 30 seconds per move allotted in the Finals: 90s/5m/75/0/6h/5m. Only 75% of unused time is added to the reserve up to a limit of 4 or 5 minutes, respectively, to encourage moves at a steady pace rather than many quick moves followed by a long think.
Players are seeded #1-16 in the Open Classic based upon their WHR Rating, precluding the possibility of obtaining a high seed based upon formulaic bot-bashing. Players will be re-seeded #1-8 in the Finals based upon order of finish in the Open Classic. A higher seed in the Finals should provide for a slightly easier schedule, of course, but also higher priority for a bye in later rounds. Standings will be updated each round in this Wiki. To read the crosstables, “S 7 L” & “G 14 W”, after 2 rounds for example, means the player in that row Lost with the Silver pieces against player #7 in round 1 and then Won with the Gold pieces against player #14 in round 2. The opponent # can either be an initial seed or current rank, depending upon the table, but in both cases the player # will always correspond with the left-most column in the table.
Registration for the event closed on 1 January 2010 with 16 participants. This is the second straight year in which the number of participants has decreased from the previous championship, but this is the strongest field ever with an average rating of 2014. This year’s games should be much more competitive than ever before, especially in the early rounds of the Open Classic. Karl Juhnke (Fritzlein) and Jean Daligault (chessandgo) are both hoping to win their 3rd World Championship title while the other 14 players will all be competing for their first. Of the 61 players that had competed in any of the previous six World Championships, 12 have returned in 2010 plus we have 4 new players: Simon Lambert (Simon), Antti Laine (Nevermind), Eric Momsen (Nombril) and Vladan Majerech (Hippo). Interestingly, no player had ever before returned to the World Championship after missing a previous tournament. But this year, we have three returning players that did not participate in the 2009 World Championship: Paul Mertens (PMertens), Christopher Bovee (ChrisB) and John Hoody (fritzlforpresident).
Open Classic Results
Players are sorted below by their original seed with current rank shown in the second column. Current rank is determined first by number of wins, second by SoS = Strength of Schedule (explained below) and finally, any remaining ties are broken by higher WHR (or equivalently, by original seeding).
- T = 1/(1+10^(2.885*(P-O)/(N+1))
- where P=Player Number of Wins, O=Opponent Number of Wins, N=Round#
- SoS = Sum of all values of T.
