Drop me a note via the contact form how to do that. Or, if you want to contribute new <=10 mov...

Re: STK for Stockfish 10

Hi Ed does this version of Stockfish has 100 parameters to tune. What exactly does it do ? Is it the same tool as Chesscombi or similar to it ? :) :) Actually I made it because SF offers no tuning parameters at all, now it can keep you busy for months :D But... you need to have some basic understan...

Re: The Start of the USB Project, for Polyglot Book lovers only

BTW, you say 40 threads, what CPU will SF10 be running on? Just one instance? Intel Xeon E5 2680 v2 3.1Ghz, 20 cores, 40 threads. With SOMU - Analyze++ the EPD of 13 million positions are split into 40 separate EPD files then spread over the available threads with SF10 running in a single thread. T...

Re: The Start of the USB Project, for Polyglot Book lovers only

By "security", do you mean the probability of the position to be in the book or the playability of the moves stored in the book, for said position? Both. I'd be surprised if the idea doesn't end being sound, i.e... doesn't produce good results in testing. If results are favourable for 1s vs 100ms, ...

Re: SOMU 1.2

There have been several silent updates to fix some SF crashes (when using Analyze EPD) due to all sorts of garbage EPD positions. Added new function: EPD Legal Check It's highly recommanded before running large EPD sets with Analyze EPD or Anylyze EPD ++ to check an EPD file first to avoid SF to cra...
