Test 40 games at 1 minute + 1 seconds
Cfish 280319 – Brainfish 170419 both without book.bin: +5 =32 -3 Both engines are BMI2
Windows 10 PRO Procesor: I7-4790 CPU 3.60 GHz; RAM: 32.0 GB; System type: 64-bit
Values are roughly equal, but I prefer Cfish to correspondence chess. It seems to me more accurate. In addition, I do not know if Brainfish is using Book.bin for infinite analysis.

Infinite analysis uses only the work of the engine. In analysis the book is used only as a referment for the possible opponent's moves.

And then, what setting do I have to do on my PC to help the engine with Book.ctg? Full analysis or Deep position analysis?
Now I find I do not know how to use my computer for analysis ...
Thank you very much for the explanations!

When it comes to analysis the only help of opening book is indicative to the user for the move to make. I use them alot when I have to change the lines of my opening book. Strong correspondence engine + strong computer cpu + good ending tablebases (possibly Syzygy) make the deal.

Thank you very much for the patience you had with me to solve a problem that I was very interested in! Now I have a perfect understanding of what is in correspondence chess.
You have all my respect!

Thank you very much!
We offer so many powerful engines that it is very difficult for us to choose the best. Along with these, I also expect Sugar 1.6.2, which will appear at the end of June, according to the information on the official site.

I hope so, I need to include it in a What'sthestrongest. Anyway if you want to thank me properly there's a plus sign on the right side of every post, that worths like a "thank you".

I did the way you recommended me and I understand why it's best to click on the plus. Thanks a lot for your advice! "The man who lives learns."

I do not understand the difference between a modern engine and a POPCNT one. I have already asked this forum, but no one has responded to me until now.

@ Ginelu
I think in general, the 'best' is x64_bmi2, then x64_popcnt, then x64 and x32 is 'worst'.
I am not an expert but try to use the best and if it crash move to the next one and so on.
I hope that works

Analyzes on the i7 are done with x64_bmi2 engines, but the i5 laptop only works with modern engines and x64_popcnt, so I wanted to know which one is stronger. Thanks for the explanations! I'll do some tests to find out which version is better.

Modern, as its name says, is for modern computers, for example an average desktop x64 processor. POPCNT is mostly for mainframes (read as "supercomputers) not supporting BMI2. POPCNT is used by the most powerful AMD ThreadRippers out there, while BMI2 is used by the Xeons and all the Intel family top CPUs.

  I hope I understand well. When an engine has both versions (modern and POPCNT), I will use the modern version of the i5 laptop. Thank you so much for the explanations!
