2009 World Championship

We have 18 players registered, and thus five preliminary rounds. On average, you would expect 9 players to finish with a winning record (3-2 or better) and 9 players to finish with a losing record (2-3 or worse). If it turns out this way, there will be one 3-2 player who does not qualify for the finals, based on having the weakest opponents of all 3-2 players. However, if a couple of players drop out (as happened last year) then perhaps there will be only 8 players with a 3-2 record, and all will qualify for the finals.
Returning players this year are rated, on average, 15.5 rating points higher than they were last year. This is a major change from previous years, where the year-over-year rating gain of returning players was always about 100 points. This is probably due to the deflationary effect of starting new players at 1300 rather than 1500, and also the deflationary effect of fixing the rating of ArimaaScoreP1 to 1000.
Good luck to all!

A warning regarding selecting times...
I usually use a bookmark to select my availability:
http://arimaa.com/arimaa/gameroom/selectTimes.cgi
But Omar just sent an email saying to use:
http://arimaa.com/arimaa/wc/2009/selectTimes.cgi
(with some authorization keys after it)
And they have a different set of preferences stored for me. So, just in case anyone else uses a bookmark to find their time preferences, be careful!

I accepted Omar's invitation to be tournament director again this year. Good luck to everybody and I will try to be as fair as possible. Please review the tournament rules. In general, players are responsible for having good connections, connecting on time, and playing good moves. If the game site has technical problems or the coordinators make mistakes, we will do our best not to penalize players for events beyond their control.
In the past, pairing algorithm results occasionally didn't meet the published criteria and human correction was required. The published criteria will continue to take precedence.
Make sure your game time offsets from GMT are correct. This way you will connect at the right time.
The current rules don't explicitly state how a partially finished game is handled if the site goes down in mid-game. This happened in the past and I believe the best response is to continue the game from the position and clock settings when the site went down.
Otherwise the posted rules have evolved to handle things pretty well. Have a great tournament!

Just want to give a big thanks to Ned for accepting to take on the TD role this year; and for the great job he has done in past years. Believe it or not the tension of something going wrong during the tournament feels more manageable to me knowing that Ned is there as a safety net to make sound decisions. Hopefully things will go smoothly and we will have another enjoyable tournament with some spectacular games 
Karl were you planning on covering the games. If so maybe you might need help in the early rounds since there are many games. I could volunteer to help you with a couple games each week, but my level of analysis is not very deep. I hope others can also volunteer to help if needed.

I can also help with a few games each week. And because the tournament format is similar to last year's I can generate the standings on a weekly basis with the code I created last year.
Deep analysis is not required for the Open Classic summaries. Last year most of the recaps were only 1 or 2 short paragraphs. Only a few complicated or marathon games had long, detailed summaries -- and Fritzlein usually covers those games

Are the match times going to be publicly announced this year?
This would be convent for those of us wanting to watch the games.

I was feeling less inspired to cover the games this year than I was last year, in part because I want to devote a healthy chunk of my Arimaa time to the Mob game, but given the offers of help, I can hardly refuse. Also there will be only nine games per round, as opposed to thirteen per round last year.

Yes, but the games are scheduled on Tuesday nights this year instead of Monday nights.

Sorry about the delay in getting the games scheduled for the 1st round. I ran into some unexpected issues. They are fixed now and the players should have received an email with their game times.

No problem. As long as we keep tweaking the format, there will be glitches.
I notice that the game times are nearly evenly distributed throughout the weekend. Did you change the scheduling code to encourage that, or did we just get lucky?

The ratings were fixed on Jan 3rd, just that the program to list the registered players was always using gameroom ratings. I've changed it to show the fixed ratings now.
