Stockfish sewing machine

Re: A community project CCMT

I strongly agree with all of those (it is surprizing that any of those positions could have given an engine pause, since they are all obvious moves).
I guess that 90% of the people here would play those moves after a couple seconds.

Re: XI-r3 Release

For people having trouble in interfaces like aquarium, try turning off the new WLD feature. It is non-standard stuff emitted by the engine (invented by the SF team, not Mike). It should be allowed because it does not violate any rules, but several GUIs do not handle it right. But it is a UCI paramet...

Re: XI-r3 Release

It might be worthwhile to see if the improving bug that Ronald found affecting Cfish has been fixed in Stockfish. I have seen bleeding edge SF also go manic depressive. I looked and the fix appears to be in the latest SF code. You might want to check XI code and see if the "improving" function is i...

Re: Cfish is back!

Ronald has brought Cfish back in sync with Stockfish-dev. Both have "bench signature" 4882833. https://github.com/syzygy1/Cfish This is very good news. I notice that the name for the official release version is: Cfish-cfish_11_fixed It makes me ask what was broken. I also see that this version is m...

Re: A community project CCMT

I think your idea is a good one.
I welcome all suggestions.
As I said, fun should be a very important criteria.

Polish users cut off from TalkChess

I have a friend in Poland who is not able to access CCC.
I remember that there was some European access problem a while back.
Maybe it did not get fixed for Poland

Re: Throwing out draws to calculate Elo

The only one that really puzzles me is hgm, I mean you are a physicist. The Heisenburg uncertainty principle, the laws of thermodynamics, quantum physics, Schrodinger's cat. If there is any person on this board who should understand uncertainty, it is hgm, but you have no understanding of uncertaint...

Re: A community project CCMT

These positions were all chosen because they game *some* engine fits, but the tragic problem is I do not know when and I do not know which engine since they are not recorded in the database. So it could be crafty in 1990 that had a hard time, but it is laughable today because engines and machines ha...
