Silent but deadly

Post by Dann Corbit » Wed May 07, 2008 7:16 pm

This is an EPD test that is designed to help tune chess engines. All of the positions are fairly quiet, and the best move is not a capture. The evaluation for the position is intended to be below one pawn for a one minute search. There are a few positions that have a score a bit larger than one pawn (marked polar) and there are a few positions that have more than one solution (marked Multiple solutions). I would like to see suggestions for replacements for the positions with comments attached.

For each of these positions, ultra strong chess players chose the marked best move, as well as many strong chess engines (including Rybka and Naum at 150 seconds). So the test suite should be fairly well debugged. However, I will be very interested in any defects that can be discovered.

The main intention is that you can use it to tune your chess engines at shallow depths for positional or otherwise quiet moves.

Dann Corbit wrote:This is an EPD test that is designed to help tune chess engines. All of the positions are fairly quiet, and the best move is not a capture. The evaluation for the position is intended to be below one pawn for a one minute search. There are a few positions that have a score a bit larger than one pawn (marked polar) and there are a few positions that have more than one solution (marked Multiple solutions). I would like to see suggestions for replacements for the positions with comments attached.

For each of these positions, ultra strong chess players chose the marked best move, as well as many strong chess engines (including Rybka and Naum at 150 seconds). So the test suite should be fairly well debugged. However, I will be very interested in any defects that can be discovered.

The main intention is that you can use it to tune your chess engines at shallow depths for positional or otherwise quiet moves.
Thanks Dan, I think this will be really useful. As a quick test, Gaviota solves only 55% in 1 second, so there is a lot of room for improvement here. One thing that I needed to correct was the bm moves that were not pgn standard (I think). For instance, it was 0-0 rather than O-O (zeros vs. letter O) and the long notation. I corrected this manually. I will repost it but I am hesitant to do it if you have an electronic way to correct it (I do not want to spread a potential typo if I made one). Le me know.

Thank you Dann !
I'm rewriting the eval of Cyrano and those positions are really helpfull.

DanaSah solves 115/134 in 1 second.

I would divide into two test, a test with only the positions of castling and the other with the rest.

Great stuff Dann. Thanks for sharing, very kind of you!
Except for the already-mentioned "0-0" replacement, this imported just fine as "test set" in Chessbase. Just curious, how did you collect this suite?

I collected the set in the following way:
I took a large collection of super GM OTB games at tournament time control and also GM correspondence games.
Then I filtered for frequently played positions where there was general agreement.
Then I analyzed the games and threw all all positions with a score of larger than +/- 100 centipawns.
Then I threw out all capture moves.
Then I reanalyzed with several different chess engines and threw out the disagreement positions.
Then I verified with Rybka 2.3.2a and Naum 3.1 at 150 seconds.
Then I verified with Rybka 2.3.2a at 300 seconds.

I am not fully satisfied with it yet, but I think it has value.

I took the time to run these on my laptop, just to see what it would say. I didn't see any specific directions on how long to think or whatever, so I took a target of 60 seconds per move, not quitting early if it agreed at some depth. This means that a solution has to be held thru 60 seconds before it is counted as correct, if it finds it early and then switches, it is counted wrong...
