What I'm really hoping for is not that you disappear again and next year come back early enough to get in form, but rather that you take up Arimaa seriously enough to improve to levels above your previous best. I miss your unique and creative approach to Arimaa, and as fun as it is to have you back for two months of the year, it would be far more fun to have you back year-round. That's "what I want to say here".  |

no promises, but I do miss arimaa and the community myself ...
tactically I was clearly stronger before ... but my main problem this year was that I was strategically clueless ... so I guess I mostly agree with your reasoning ...

Simon, sorry about that. I've sent an e-mail to Omar requesting the game time be re-scheduled 1 hour sooner. But with the game scheduled to begin only 28 hours from now, I'm not sure if he would want to do that...?
EDIT: I didn't realize the game times were still tentative. I've switched the 9pm time slot to the highest priority.

Sometimes it's tough having to choose between real-life commitments and on-line fun. But the way I figure it, if your real life is so good it pulls you away from Arimaa, you must be a happy man!  Peace and Joy to you, on and off the board. --Fritz

Arrrrg, you're right. I thought I was doing a good thing by letting the players know earlier when their games will be, but I forgot to consider that maybe someone had not updated their preferences for next week yet. OK, I'll have to be careful to only run the scheduler at the specified times regardless of if the round finished early or not.

I hope all those in the spectator contest will keep in mind that I am the gameroom ratings favourite against adanac  . Of course since he is seeded first, this is also clear proof that humanity has been backpedalling for the past year, and that the 1-4 gap is now negative  .

Heheh. So says the man with the 112 RU. But anyway, I noticed in the first round of the spectator contest that the underdogs had fewer backers than what I considered their true odds to be. Therefore, I am backing all the underdogs in the second round, including, of course, Adanac.

I considered your second straight victory over Tuks a sure sign... that you would give me grief in the forum.  Congratulations on striking a blow for the status quo!
It comes back to me suddenly that when I finished off the podium in 2006 I considered it proof that I was washed up and that all the new players had passed me. I'm glad that my judgment isn't always on target; it would make life so boring...

I'm not sure it is supposed to line up with the true odds. Wouldn't that only be if there was only one prize for the winner of each prediction? But there is the additional 1 point for everyone backing the winner that tips us toward backing the favourites.

I don't know if anyone has mentioned this before, but I think it would be great if there were an additional tie-breaker for the spectator contest. The luck of being logged in at the moment the next round is open for predictions can make all the difference if two people both makes perfect predictions. I think that a more fair tie-breaker would be any one of the following:
- predict how many pieces (gold + silver) are still on the board at the end of the game
- which move # does the first capture occur (0 = no-capture prediction)
- other possibilities that I don't like quite as much are winning method (g, t, n, etc.) or total game length in minutes.
I would prefer spending the extra 30 seconds on 4 extra drop-down selections over feeling that I must submit my predictions the nano-second they are available. I was quite pleased to see 38 participants in the 2010 Spectator Contest! I hope we have more every year but the current tie-breaker system certainly was not designed to handle large numbers of players.

I agree with Adanac about the spectator contest. The time of entry is a poor tiebreaker. Last week Elmo entered her predictions as soon as she got the e-mail saying it was time to predict. On the chessandgo vs. The_Jeh game, she predicted 37 moves, just like rabbits, the prediction winner for that game. Rabbits won the tiebreaker because he entered his prediction two minutes and twenty-one seconds earlier. That's a little bit silly: how can you do better than entering predictions immediately?
Of your proposed alternative tiebreaks, the move of first capture appeals to me most. That information is pretty easy to extract from the movelist, and it does display some knowledge about the playing style of the combatants, e.g. whether they like to trade, like to race, like to advance rabbits, like to wrestle, etc. It would provide a layer of discrimination that is based on predictive power.
It could still end tied, though, in which case I guess one could fall back on the time of entry for second tiebreak, especially since it is already coded.

Thanks for the suggestion Greg. I like number of moves to first capture also. I've made a note to add this next year.

Thanks Omar! Not only would a tie-breaker prediction improve fairness but it would also provide more interesting data. How strong is the correlation between predicted winning move # and predicted first capture # for various styles of play, for example?
I realize that there was a flaw in my No-Capture Game = 0 assumption. The player with the lower tie-breaker prediction shouldn’t win the prize. If there had been a Spectator Contest for the Omar-Simon game (silver in 35 moves with all 32 pieces still on the board at the end).
Suppose Elmo predicted Simon in 35 with first capture at 34
and rabbits predicted Simon in 35 with first capture at 9
In this hypothetical example I think it’s clear that Elmo’s prediction is more accurate and so maybe the winning tie-breaker score should be 36, one more than the winning move number (rather than 0).

That sound like a good convention for measuring who is closest without being exactly right. When there is no capture the move of first capture is defined to be one more than the number of moves in the game.

I'm looking for some technical assistance with the Wiki:
http://arimaa.com/arimaa/mwiki/index.php/2010_World_Championship_Finals% 2C_Rounds_3%2B
Question 1: How do I force a carriage return in the sentence "Position after 24g Ec5e Ed5n Rh3n Rh4n. SILVER to move" at the bottom of the diagram below? Sometimes it will not put the two sentences on the proper row.
{{arimaa diagram|=

|Position after 24g Ec5e Ed5n Rh3n Rh4n. SILVER to move.
}}
Question 2: Using "!!" will bold and center an entire row in a table such as the one below. However, is there a way to only bold rather than getting both?
