Sorry, but Rybka is weak in mate finding . I didn't bother even test it. And sometimes 4 mover is too much for it.

Here are some deeper mates (dm 19 or more) that I analyzed with Rybka.

Code: Select all

Have you looked at any of these problems with modern hardware and a modern engine? The reason I ask is because MANY of the proposed solutions are wrong.

One example is this one:

Code: Select all

6R1/8/2P5/3K4/1P1PpP1P/p1p1P1P1/rpPp3N/qnbrkBB1 w - - acd 28; acs 385; c0 "Analyzing engine Rybka 2.3.2a"; ce 0.00; dm 26; id "ChestDB.5826"; pm c7; pm c6c7; pv c7; 
The proposed solution is 1.c7 which is a stalemate.



Of course, there are many others that "seem" to have incorrect solutions as well.

Response too long. Look at attachment for response.

Err, in the other forum, because you can no longer attach files here:

Thanks for the updated file. I have gone over it just briefly.

After I posted I decided to just do all of them. I finished my first pass this morning. About 90% of them I've finished. I accidently got some other positions mixed in with them so I can't give you a clean count. But, if you interested I can send a PGN to you. There are quite a few differences between what the original file seemed to indicate and what I found as solutions. After looking at the second file there is still quite a bit of differences. I don't really have a good grasp of what each field in an EPD file is, ( I don't use them much ) so maybe some of the differences are just me not understanding what I'm seeing.

I guess I could just start posting results one position per post. I haven't counted the differences yet, but there is probably 50 or more of them.

I would be interested in your results.
PGN is fine.

Decided to just post them here. The first group is DM19 from the first file. I did them mostly in reverse order so they're not in the same order as you listed them. All were solved by SF dev.
