Hi Dann

Fantastic collection.

Thanks!

Hi Dann

Fantastic collection.

Thanks!

Richard

I am glad you find some value in it.

I am currently analyzing the positions with increasing effort for the positions with greatest popularity.
When my first pass of analysis is done, I am going to group them into:
1. Confirmations (Rybka's analysis agrees with the most popular move)
2. Arbitrations (Rybka and the move set do not agree on the best move, but Rybka's move is a popular choice)
3. Controversies (Rybka chooses a move that is very rarely chosen)
4. Novelties (Rybka chooses a move that is not included in those chosen by the experts and by chess engines).

For groups 2,3,4 I will reanalyze at increasing depths and also by analysis of the forward positions and by examination of won/loss/drawn statistics to find out what the best move choices really are.

Dann, keep up this great work. I have not had time to use them yet, but I believe that this sort of positions are way much more useful than typical tactical sets. I am using now the previous 134 silent positions to test tree sizes. They are great.

I uploaded the classified version. You can find it here:
http://www.zshare.net/download/13013562c694dcae/

There are 493 in category arbitrations.
There are 1691 in category confirmations.
There are 478 in category controversies.
There are 142 in category novelties.
I plan to reanalyze all of the positions that are not in category confirmed at longer durations.

[Dann Corbit]

Is one hour of Rybka analysis on my machine enough? I ask because after one hour at 3 GHz x 4 threads, I still get some novelties. Are these move well know? Are they played by lesser players? Are the most frequent moves really better than these choices?

Hi Dann

Fantastic collection.

Thanks!

Richard

I am glad you find some value in it.

I am currently analyzing the positions with increasing effort for the positions with greatest popularity.
When my first pass of analysis is done, I am going to group them into:
1. Confirmations (Rybka's analysis agrees with the most popular move)
2. Arbitrations (Rybka and the move set do not agree on the best move, but Rybka's move is a popular choice)
3. Controversies (Rybka chooses a move that is very rarely chosen)
4. Novelties (Rybka chooses a move that is not included in those chosen by the experts and by chess engines).

For groups 2,3,4 I will reanalyze at increasing depths and also by analysis of the forward positions and by examination of won/loss/drawn statistics to find out what the best move choices really are.

Firstly, a disclaimer: I have nothing at all to do with programming. So I cannot say much about all this content.
I just wish you that your compilation should be a big contribution to the history of computer chess. It seems it might be, if someone can incorporate it all into an already great program. Whatever remains.
Good luck.
