Oh, that makes sense... I wrongly assumed 2464 was the previous rating for sharp. Thanks for the explanation!

Thanks, 722caasi, for being the first one to complete all four games of the screening. I was very impressed with your last game against sharp; you had a comfortable material advantage and a solid position as well. Thanks for showing us that sharp is beatable.

Thanks for ignoring the ends of my games 
Sharp isn't too hard to beat if you don't get swarmed and you can play an endgame. Best way to not get swarmed? Tie down their elephant. Thus, give horse hostages.

Sorry about that one thing.

This could be a very valuable tip. I'll be watching further games to see how this pans out.

I meant at quad and/or at marwin. Marwin, check Based on that sole game, I'm not impressed by marwin's trap control (and not by its treatment of advanced rabbits either, like sharp). Is bot_quad available to play only when aaaa runs it?

The_Jeh's win over marwin increases sharp's lead to 2.5. The drama of the screening has changed from "which bot will win?" to "can anyone beat sharp?" (besides chessandgo, I mean)

I hope there are still players whose have a chance. But sharp looked like easily be in top 10. I hope Tuks and Adanac would concentrate better for the other try.
Wow good news for humanity ... Sharp totally lost in the ending with aaaa.

Just as I say it, it becomes untrue. Aaaa's win over sharp cuts sharp's lead to 1.5. Plus Manuel's win over sharp and Hippo's loss to marwin in uncompleted pairs have narrowed the gap in performance between the two bots to just 2274 to 2158 in sharp's favor. This may yet be a race for which bot qualifies, and the Arimaa Challenge might not yet be in danger.

What is the link for screening results? Previously I used the link "Play the screening bots" from announcements section, but that link is not always available (and is not available now). It would be good to have a stable link for results (maybe in coverage or tournament description pages).
Edit: Now announcements section is updated, so I can answer my question about the link: http://arimaa.com/arimaa/challenge/2011/showBestBot.cgi. And the new version of the page is great - track all screening games and comments in 1 place (thanks!).

Omar, I second foggy's thanks for listing all the screening games in one place. That makes it easy to catch up on what I missed, even though nobody was chatting about it in the chat room today.
Tuks victory over marwin puts sharp's lead back at 2.5. I'm thrilled with the broad participation in this year's screening. At this rate it seems possible we will surpass even last year's record participation.

The plot thickens. Marwin's victory over Harren cuts sharp's lead back to only 1.5. In addition, marwin has pulled ahead in performance rating, 2128 to 2104. This reflects marwin's victories in several incomplete pairs. If all pairs are completed at the level of performance so far, marwin will probably pull ahead.

If a computer won the Arimaa challenge it would be huge! Newsworthy! But...
Would people actually take it seriously if the absolute best Human players weren't represented? I'm thinking about that huge schism/fiasco in the chess world, where the Official World Chess Champion from the Official World Chess Regulating Body, FIDE, was not considered the actual best chess player in the world by virtually every chess player and media organization, because Gary Weinstein (Kasparov) didn't compete in it.
I'd hate to have to see anybody lose $10,000 twice, because the first time it seemed tainted...

The $10,000 prize will only be won once, not twice, but yes it will be a shame if the #1 rated player does not participate in the year that the prize is claimed by a bot developer. Even if the # 1, 2 & 3 ranked players are all defeated you could get different criticisms if the # 4, 5 & 6 players were a combined 6-0 against the winning bot in the screening round (it’s not clearly better than all the best humans after all?) But, in both cases, I would consider that a legitimate victory by the bot developer against steep odds. If the prize is claimed before 2020 under any circumstances then I’d say that the developers have gone a lot further in 15 years than I ever expected they would when I joined the Arimaa community in 2005. It was only two years ago that a bot lost a horse handicap game in the Challenge Match, for example.

It looks like there's hope for Marwin yet...
