I am downloading the Nalimov 6 man EGTB files.
There have been various interruptions and restarts and I am nervous about the correctness of the files.
I seem to recall a routine to validate the correctness of the files.
But I can't seem to find it.
Does anyone know where I might locate it.

There are arbitrary precision libraries for many languages
Perft 14 and 15 have already been counted:

look at the posts by zenmaster.
there are lots of posts, so you will have to do multiple copy/paste operations to get them all

There are PGN versions created in this thread

I notice in the downloads that you have a threadripper build.
I have found that (at least for long analysis periods) the builds with znver2 are not as fast as my ordinary modern builds.

RE: "When the Chess-AI is computing its "best move" what algorithm is it using???" The algorithm is a neural network. There is a file of floating point numbers. The learning phase decided what features from the rules of chess and the configuration of the board are important. It writes these floating...

What was wrong?

Is it always in a way ahead or way behind situation? It could be fail high and fail low that never resolve and it simply does not respond in time. If it were as simple as that you could just add more time checks. Can you replicate the problem on your equipment? Especially, if you can get it to repro...

Another side point: Early in engine development the most important thing to strive for is correctness. I invite you to read Fabian Letouzy's Fruit source code for an illustration on how to do your code work. It is a general software principle that holds in all disciplines: first make it right, then ...
