Sentimental value, perhaps.

I suppose I could beat Duke, with my eyes closed! Deep Duke, well, I would probably atleast need to know what move it made.


Oh sorry, I was thinking of Brutus RND. I mean, at what computer elo is it atleast worth bothering trying to beat?
Even a good few hundred elo better than the top of the 40 on that list, all one needs to do is to exchange the whole time, until computer makes blunders, then you take what you're given and then soon deliver a simple checkmate. There is no need to even think of the value of pieces (besides the normal standard values).

[Carlos777]

Yes, these engines are weak, most of them because of terrible bugs, bad time management, illegal moves, others are just random movers like Brutus RND and Ram 2.0.

My first goal was to test all engines as possible below 1700 ELO, but I included many engines with a ELO between 1700 and 2000 and few with an ELO better than 2000.

This tournament (Bottom 40 engines) is for these weak engines to have a more accurate rating, some like Deep Duke had no points in my previous list. After this tourney, it can have a better rating. Also, at the end I'll post the bugs showed in these games and which of these engines are worth testing (not in the sense of strenght, but specially that comply with the rules of standard chess and do not lose on time)

I guess some 1200-1300 ELO person could have problems to beat some of these engines, like Fimbulwinter or DarkFusch.

Regards,
Carlos
