Re: VirtualCoffin

It doesn't appear in the list of Windows feautures. Neither in the dialog for enabling / disabling them, nor when the list is requested with the aid of the dism.exe from the command line. So I can only conclude that it must be an optional feature, and that I don't have it installed.

VirtualCoffin

Lately I have been doing all my development work on Linux, running Ubuntu in VirtualBox on my Windows 8.1 host. Unfortunately, as of today, this ceased to work. When I try to boot a VM, I get the dreaded VERR_VMX_NO_VMX error, telling me that VT-x virtualization is not available. When I start the BI...

Re: Creating chess variants on the spot

Centennial Chess has 'Rotating Spearmen', which behave somewhat like your Directed Queen. Except that they can only have 3 orientations rather than 8. But then they can move both forward and backward along the ray in that orientation.

Re: how will Leela fare at the WCCC?

Do you remember what the rule change was? I would like to see if it is still a problem. Hi Mark, I'll tell the story in a private message. The rule itself is irrelevant, as the point was about the (non-democratic) procedure. The rule was to max the number of cores to 8. That excluded custer program...

Re: TCEC should reconsider the ban on Ethereal

At the WCCC? Normally moderators would only see postings that are reported, and they would only act against those when these violate the charter.

Laskos, what do you mean by "... and another game of Leela where she did not played..."?
One Leela game was postponed, because its operator was absent due to a domestic emergency.

It’s mainly Caesar David levy and king jaap van den herik. Are more people involved ??
Well, as I said, the rules are mainly determined by the participants. Within reason, I suppose; they could probably not decide to play Backgammon instead.

Re: Testing a set of engines

It depends on how large the strength difference is. If the list consists of, say, Stockfish, Fruit, Fairy-Max, Chad's Chess and POS, 10 games per pairing would be more than enough, as every match would end in 10-0. If the list consists of engines that to all intents an purposes are equally strong, y...

A one-person democracy.
Not at all. Before every WCCC there is a players meeting, which basically decides everything. As a former participant I have often been approached by e-mail for my opinion on some proposed rule change.

Re: how will Leela fare at the WCCC?

The problem is that the ICGA is set up as a democracy, and that many of the participating programmers are not in favor of this. Pretty ridiculous, but it is true.
