Because of the circumstances this year we decided to play the 10. Atticus Open/Summer Tournament 2020 online using Lichess.org.
27 Players, three from Dortmund, Germany, have registered for the tournament, two players dropped out: one because he has problems playing online, the other because his computer sadly "took its last breath" and "went to the happy hunting grounds" ...
The first three rounds have now been played. There are lots of really good and interesting games. You can replay all games on our website. Simply click on "10. Atticus Open/Summer Tournament 2020" or go to "Atticus Open Championship 2020" or click in the List of Fixtures in the column "Result" on the result of a game.
Have a look at the table and the ranking: only Colin Horton from Waterloo Chess Club has won his first three games, but nearly every player can still wil this tournament. We are looking forward to more exciting rounds.
Here are some explanations of the names (abreveations) of the tables:
- G = number of games played
- Pts = Points
- Bhlz = Buchholz-Ranking-System; for explanations please read:
Wiki: Buchholz System and Tie-breaking in Swiss-system tournaments
- SoBe = Sonneborn–Berger score; for explanations please read:
Wiki: Sonneborn–Berger score and Tie-breaking in Swiss-system tournaments
- di-ma = direct match result; if Points, Buchholz-numbers and Sonneborn–Berger score are the same for two or more players, then the direct match result decides about the ranking.
These Tie-break systems are common in chess tournaments. Of course there are some others too. If you are interested in this topic, please let me know.
All players are very relyable and co-operative, there have been only some very minor problems and I expect that there will be less or no problems in the remaining rounds. Thank you all.
Cheers,
Martin
P.S.: Because the ECF wants to introduce 4-digit ELO-based grading numbers and because these grading numbers are established internationally for many decades, we are using these numbers in our tournament. Have a look at the "Unofficial Grading Analysis". Here are some explanations about ther different columns in this table:
This table shows how the DWZ-grade of a player develops during the tournament.
W: achieved points
We: expected points
E: development coefficient
+/-: differencs between the new grade and the old grade
