Re: Pyrrhic, Fathom for Humanoids.

Al the defines you mention like WHITE_KING, etc. are in tbchess.c, which is included in tbprobe.c. None are in the interface, and none should be visible to clients of Fathom.

Re: Summer time - how does your PC cooling solution perform?

I have done a little more testing/tuning on my air-cooled 3970x box. I should mention, this box has eight case fans and most of those are running off +12 volt supplies so they are full speed. You really do need that, otherwise the air cooler just can't keep up with the thermal load. Btw. I like Noct...

As I mentioned, I think a lot of the short losses are due to bad book lines or a bad decision shortly out of book. Most engines out of the very top ranks still play openings rather badly.

Re: History of Memory Wall in Computer Chess?

I wrote a lot of Z80 assembler back in the day, including a word processing program that was sold commercially. That program could not fit in 640k RAM so it had to use disk overlays: the printing module and editing module were loaded into RAM as required and couldn't be present at the same time. A l...

Re: Summer time - how does your PC cooling solution perform?

By the way, re cooling, I am testing out my new Threadripper 3970x system. I did not want to water cool it, so I have an air cooler made for the TR4 socket. First time I started measuring the temps they seemed awfully high. However, this thread: https://community.amd.com/thread/247177 seems to indic...

Re: Summer time - how does your PC cooling solution perform?

Does the big server run on 115V? have you a put watt meter on them to see how much they really are taking up? I think A/C is the killer, esp. in hot climates. Amazon has a lot of options fairly cheap meters. Solar isn't cheap and the break even time is years. Good luck. Yes, the big server is 115V....

Re: this will be the merge of a lifetime : SF 80 Elo+

Can someone explain this project to me in small words? I gathter it is basically Stockfish with a NN eval, or? And is the neural net part running on CPU, or GPU? Apologies, I have not been following the lengthy threads on this.

Re: New chess rig

FYI, I flashed the BIOS to the latest version and then it worked (fortunately Gigabyte has a way to do this via USB that runs off a ROM and so does not even require a bootable system).

Re: interesting correspondence game

In general, .. c4 tends to be a bad move in the French, it just locks the pawn structure and leaves Black with little counterplay. There are always exceptions, though.

10. Qf2 is in fact the newest trend in this line, it appears.
