Official Release of Ethereal 11.75, supporting MultiPV

Hello all, Its been been about 5 months again since the last release, and I'm back with another update, which is a quite a bit stronger than the previous release. I was forced to take some time away from chess development for quite some time dealing with some medical issues, but I think I'm back now...

Let it go, Daniel. He’s not worth it. Andy’s personality defect is punishment enough. Let him grouse with his fellow misanthropes.
This is the kind of banter I like to read. Not the drivel that Daniel writes. Well put Dkappe.

Re: Fritz 17

You were constantly taunting me with the crashes at the TCEC You have a bizarre understanding of the word "taunting". Pointing out that your engine crashes is not taunting. Pointing out that your engine continued to crash for multiple seasons is not taunting. Pointing out that its shameful that you...

Re: Fritz 17

It is interesting that you consider Scorpio to be a derivative of Lc0. I strongly suspect that Daniel Shawul would take exception to this description. He is not alone in his thoughts. Daniel or the original poster? If the latter, then you’ve produced a real head scratcher. Is leela chess, as the fi...

And they use now 256 cores! But only 128 for Ethereal and Fire. No support to higher value?
Was using 256 threads at first. I dropped to 128 to go from hyperthreads to realthreads.
Could be a slight elo loss, but I don't have that data.

Re: Fritz 17

I guess they will choose Fire. Ethereal is a little stronger, but open source. Xiphos is a hair weaker, but open source. All the stronger engines are either NN or commercial. Fizbo is 50 Elo weaker than Fire. If they choose an open source engine, it is hard to compete with free (why will I pay $75 ...

Re: For those that like to toy with Ethereal...

No difference in my test, but I discovered that Arena was logging like mad (I had a 550 MB arena.debug file) so I think the result cannot be trusted. Program Elo + - Games Score Av.Op. Draws 1 Ethereal-stopr : 3333 11 11 1475 50.1 % 3333 58.6 % 2 Ethereal-ethpr : 3333 11 11 1475 49.9 % 3333 58.6 % ...
