So probably just go for Sf12 at depth 20 to achieve 3200.
That is the depth of the data generated by Bojun Guo for his opening project.
He has more than a billion nodes calculated.

You can find this entry on Ipman Chess benchmark: 47.371.167 4x AMD Opteron 6276 @2.3ghz 64threads base Dann Corbit I guess that a good place to look for assember locking is in the Asmfish code. The original stuff by mohammed was brilliant. He also wrote the first ...

Re: Perfect chess engine elo ( 32 men TB) can be within 200 of Stocfish in Tcec LTC conditions

I even see no proof that stockfish can lose games with white in TCEC conditions. A proof can be to show me one game that stockfish lose with White from the opening position in TCEC conditions(when stockfish does not use book). I guess that the main difficulty here is that there are exactly zero gam...

Re: Good quality games

People already collect CCRL, CEGT, ICCF, etc. games. Your data will be interesting if: 1) it is better than the current data sources OR 2) it has interesting theoretical novelties OR 3) it focuses on openings that are in vogue and other testing sites are not analyzing those openings There are other ...

Re: Good quality games

There are testing groups that do that.
CCRL
CEGT
There are contests that make even higher quality games such as TCEC.

You will have a very difficult time trying to replicate these efforts.
They have large teams of workers with lots of hardware

Re: Perfect chess engine elo ( 32 men TB) can be within 200 of Stocfish in Tcec LTC conditions

The draw prophecies are going on the assumption that chess is a draw. It is likely true but we do not know that. Another possibility is that perfect chess is a win for white. Another possibility is that perfect chess is a win for black. Play the strongest engine today on the strongest hardware today...

Twenty years from now the current hardware and software will grind today's TCEC hardware and latest chess software into powder.
Achieving a draw against a peer is not the same thing as achieving a draw against a perfect chess player.

Re: Deep Blue | Down the Rabbit Hole

I did not know about some of the intrigue sort of things and I also was unaware that Kasparov at first had a highly cooperative relationship with IBM that turned into the cold shoulder before the rematch.
And some other anecdotal things.
