As tournament director, I am pleased to announce the human defenders for the 2011 Arimaa Challenge.
Fritzlein (Karl Junke): a two-time world champion and author of Beginning Arimaa.
rabbits (Gregory Clark): a world championship finalist who defeated multiple world champions in qualifying games.
99of9 (Toby Hudson): a multiple world championship finalist and author of bot_GnoBot.
Alternate Defender: omar (Omar Syed): creator of arimaa.
Please see the Arimaa Challenge site for detailed rules and schedule. Let's give our support to the defenders, or if you prefer, root for the challenge bot.

Good luck defenders!
btw:
I'm a little bit surprised that chessandgo is not selected but perhaps he deserves some rest this year.

Omar likes to rotate the defenders each year so that more people get a chance to participate in the Arimaa Challenge.

Yes, rotating the defenders not only shares the work and shares the glory, it also gives a much better sense of how far ahead humans are. If the team was chessandgo, Adanac, and Fritzlein, and we won the Challenge match 9-0, how much would that tell you? Rabbits and 99of9 aren't far enough down the ladder to really push the envelope, perhaps because Omar doesn't feel like losing his $10,000, but even so, if they also shut out the Challenger, then we have slightly more information about the level of human dominance.

I bet that has to do with Harry Potter.

The bots are off to a start of five wins and one loss. So far it looks grim for humanity in the Challenge. Who can show us some winning patterns? Have the silicon monsters really gained that much on us since last year?

I don't think it looks that grim... There was one timeout, two games where the person was playing at blitz speed and then two games with people rated much lower than the bots.

Don't worry so much I plan to play all 4 allowed games but I don't believe I'll win even once. So don't count points won against me, I did not play last year.  also Adanac claims he was playing blitz-like.

One thing we'll always be better at than computers is making excuses.  Not that I disbelieve the explanations for our collective slow start: I see the ratings; I see Adanac's thinking time per move; I see that there was still play left when Arimabuff timed out. But the great thing about winning is then you don't have to explain why you won.
Year Pairs Decisive Winner / Score / Perf Loser / Score / Perf
---- ----- -------- --------------------- --------------------
2007 12 . 2 . bomb / 2 / 2087 . Zombie / 0 / 1876
2008 16 . 7 . bomb / 6 / 1918 . sharp / 1 / 1576
2009 23 . 7 clueless / 5 / 1910 . GnoBot / 2 / 1792
2010 25 . 11 marwin / 6 / 2065 clueless / 5 / 1960
Yes, I know that performance rating is a very noisy metric when there have only been a few games played, but the bots 5-1 record so far means they are performing at a rating of 2443!

Thanks for playing in the screening despite the odds against you. You might surprise yourself and find a winning pattern. Every scrap of information helps the defenders, and leaves us less blind going into the Challenge games.
