I started with the database GrandNd (thanks Norm) In Shredder from the Extra Menu Opening Book -> New Opening book I called it GenericNP I then Loaded this empty book Opening Book -> Load Opening book Imported t...

A couple of the graphs above have been updated with additional test results. Two different flash drives have been tested plus splitting the TB's across 2 flash drives to see how much that helps.

It seems that the improvement is quite substantial. However it may be that this position is too oriented towards tablebases access. Do you plan to test with some endgame suite ? Hi, yes I agree. In fact the position was chosen because it caused a lot of TB access - I wanted to see the difference be...

Recent changes a Blitz... 181'849 games We have added Rybka 2.3.2a 64-bit 4CPU - this is mainly to give us a comparison to 40/40, at Blitz Rybka 2.3.2a 64-bit with 1 CPU is more than a match for everyone else even with 4CPUS. Zappa Mexico 64-bit 4CPU has 1768 games and is in a clear second place. Gl...

We will have to look at th possibility of adding it

Kirill, So far the 2 short wins for black do not look like book losses to me. I am working through the 11 White wins within 20 moves. White game 1.

Short decided games analysis. I am running some analysis of our short decided games from the 40/40 rating list. Analysis is for games decided in 20 or fewer moves.

Hi, I have seen a recent test of endgame search with the 5-piece Nalimov EGTB on 2 x 4 GB USB key (of course also possible on 1 x 8 GB key). Seems all the disk access inconveniences are gone!... Which also means bitbases (Shredder 10) are no longer useful. For those who read German, see http://www....

Hi Thomas, Several times over the years I have started somthing similar - time has always killed my attempts. I will have a look to see where I got to last - it may be that you can use some of the games I have gathered to add to your database. Shaun P.S. Sorry if it takes a while to get back to you

Uri, I am testing 0.08.373 for you via wb2uci under F9 GUI (because this is how I had tested 0.08.295) Should I use UCI instead?
