About 4.7% of all games include 5-man TB positions.
But this is the wrong measure. In most games an engine will reach 5-men positions in the search and when they do, they can replace searching a whole subtree with a single probe.

Re: 7 Man Syzygy and SSD

But perfect play once a 6-men ending has been reached on the board is only a small part of the story. The phase before it is much more important (especially at longer time controls where it will indeed be rare that the engine can't figure out a 6-men ending on its own). My apologies for getting off...

Re: Wouldn’t it be nice if there was a ChessNet50

Maybe leela nets will be public domain someday..after all they are generated by the gpu power of the people. I think for Go, facebook and others have provided strong networks for free but no one has done the same for chess other than lc0. If i start a training project (after i get a home gpu machin...

Re: GM Caught Cheating in Tourn With Hidden Cellphone in Bathroom

It's not everyday where a chess news is published on a tech site. Cheating caught with picture inside a bathroom. All the news stories report that a phone was found in a toilet that had just been used by him. It is not clear to me how that relates to the picture of what seems to be him sitting on a...

Re: Eucalyptus - KPK Bitbases Generator

I published a piece of software I use in Sapeli. https://github.com/SamuraiDangyo/Eucalyptus Are you crazy? :D You attach GPL to the generated kpk table?! :D So when someone includes it, you force the cancerous GPL crap on him? I wonder why some people still believe that open source = GPL. There ar...

Re: DTM50

Besides the smaller size I don't see a very big advantage in using syzygy over Nalimov, the only difficulty is that you need permission from both Eugene Nalimov and Andrew Kadatch to incorporate the Nalimov probing code into your engine, this is somewhat difficult to get. They are smaller, so more ...

Re: delay vs increment

It seems more important to make sure that the GUI can detect engines that don't understand delay TCs. Engines might accept negative increments (and crash or - worse - behave erratically) but are more likely to complain if an unknown command or option is given or set. But UCI engines have no formal ...

Re: delay vs increment

To have minimal impact on the various engine-communication protocols, we could adopt the convention that a negative increment -S means a delay of S. There is no legitimate use case for negative increments. It seems more important to make sure that the GUI can detect engines that don't understand de...
