Re: Database snapshot

I thought he released his personal daatabse and chessDB i thought this I think you missed this relevant thread . ChessDBCN is mainly useful in the opening, I have no idea about the quality of the ranked moves (as I've been able to nudge them) but some go beyond depth 70's quality. The closer to the...

Re: Database snapshot

Let's be honest here: IDEA's algorithm is crap. I lost ALL the games, 100% of the correspondence games where IDEA was involved. I had mixed results. Drew more won many and lost few. The way it does things is nonsensical and it's almost like it wants to generate evaluation holes where a strong centa...

Re: Database snapshot

Then we are on the same page, nothing is perfect, but we can make it good enough. Provided this data, I also want to seek for alternative methods that are more efficient in improving this overall confidence level, while one can always go for higher depth/more MultiPV but that is exponentially expen...

Re: Database snapshot

in cc game play which uly tends to rely upon always. This is precisely the difference, I understand that sometimes more depth is required to find the winning moves, but it is not practical to do that for every position. So that is why the statistics, if we can raise the overall confidence level of ...
