hmmm - I always thought the definition of challenge is äh something that is not easy to be done :-P
Your camel challenge was great, because noone would usually do that and it proved just how clueless bomb really is and how easy to outplay.
I liked the "Kill all rabbits first with no piece crossing the middle line" challenge (did someone actually win that one ?)
Just another fine example of finding a terrible weakness and making a wonderful lesson in defense out of it ...
A "beat bot in x moves challenge" would not give me the same thrill

Yes, it was a rabbit-pulling exercise, when bomb was too scared to ever go on the attack.
I figured it was possible to play lone elephant forward for the entire game. But often after 5 or 6 rabbits the situation got complicated and bomb would eventually pull one of the human's other major pieces forward of the halfway line.

Well done, Arimanator! I thought it was a pretty hard challenge; I only tried it once myself before giving up.
I have a much easier challenge to propose, but one that is mind-bending in a good way: start with all your rabbits on the second row and all the stronger pieces on the first row. I've done this against my home version of Bomb, but I suspect it will be slightly harder against a more aggressive bot, so I propose Clueless Blitz as the target bot. Any takers?

Congrats, I'm glad you proved it doable - that will give David a few things to think about over the next year. Your extension is nice too. Does this mean you were left with all your pieces vs a lone elephant? What a humiliation. I'll go take a look right now.

the bar has been raised:
Bomb Lightning
Camel, dog and 2 cats - go, beat that 
Unfortunately it was only victory by repeated position and probably would have been by points if I had the nerve to play til the end (I can last minute push around rabbits quite easily  )
Omar, please add that to the Botbash-page

I expect someone to beat bomb with a camel+2 dog handicap the old fashioned way soon.
Show some disrespect to those bots.

I thought bomb was resistant to repetitions? I wonder if Omar has made that change to the rules already and this is what messed bomb up??

I would be interested in comments by our successful bashers describing the bot weaknesses they are exploiting and what could be done to the bot to address each weakness.
For example, to me it looks like horizon effects. In the E-H attack, flipping minor pieces from e7 to e5 and then pushing them to f4 and then f3 works mainly because the bot can't see three moves ahead. Humans avoid e7 and d6 in this setup. In the MDD odds game (congratulations Arimanator for finding a successful pattern), the bot can free the minor piece from d4 quite easily, but it doesn't. My guess is that it doesn't project the push to e3 and then f3, so it doesn't see the need to defend.
Is the remedy deeper searches or additional terms in the evaluation function? Bot developers would benefit from the commentary as would players.
A good debate for players is whether a bot bashing strategy would be sound against an opponent who understands how the strategy works.
