Re: CTF Survey

I am not going to vote in this thread, Harvey. For instance, Option 3; "hidden forum only visible to those who request access." What does that even mean. Members to CC will have to ask a special, extra, codeword from Sam Hull to see CTF? The usual passwords for CCC for years could not be changed, of...

Magnus loses a game after unbeaten string of 125

Not that I follow this closely but 125 games without any loss at the higest level is impressive, I don't think any world champion had such a record. Hat off to Magnus!

Re: SF new null move formula

Where is this documented ? You can look it up in the details of every commit what are the changes in the code, for this latest commit Dann is referring to it is here: https://github.com/official-stockfish/Stockfish/commit/995ee4b31105ad8c7976cc68c11fabfdc5108e63 Nullmove is Step 9 in search.cpp, //...

Re: What is this?

At first sight, it does not look so ugly to me. Only if Black has not castled and there would be no pawns on the e-file, then it would be ugly because Queen could be pinned aganst the King. But otherwise you increase Queen mobility without putting Queen in vulnerable spot so Queen position is better...

Re: An Old Engine

I agree completely that the SF team is the injured party. I don't really want to get into this discussion, but I have a feeling if you would ask someone like Marco Costalba, that he would expect it to happen with Stockfish code because for instance the GPL does not give much protection. Fruit being...

Re: Help: Talkchess site unreachable

That is too bad, that you were blocked for so long. You will have to take it up with Sam, Mike. He is the only one who can clear your location from being blocked at least I think that is what is happening, see the thread about that . The site was also slow in responding to any new posts for me, or a...

Re: Off topic: problems attaching files

Since a few months this forum does not accept attachments anymore. It could be a problem of settings, but probably the administrator would say keeping the database of messages intact has a higher prioprity and total storage is limited by the finances set aside to this forum by sponsor ChessUSA. But ...

Re: Stockfish and latest +6 ELO patch!

Maybe in some endgames there are big tuning changes still waiting, and this functionally changes just something right? As Protospring is saying, the bench right now is not really affected by a lot of endgame changes, they are not triggered in the searched positions. But it is a functional change fro...

Re: 32 bit Windows users needed ...

I just had a quick look but from that, i'm afraid these are likely not working Mike. Stockfish-022120 does open a command window on my 15 year old system, but I can't enter a command like 'uci' to test anything. Bluefish-022120 also opens a command window but gives a message saying it can not find e...

Re: Plaskett's Chess Puzzle Solved in ~15 minutes

Vondele found a bug in the use of VALUE_MATE_IN _MAX_PLY when having tablebases on board. Looks like not really a fault of vanilla Stockfish code but more of the later added tablebase code in Stockfish in my opinion. But Mikes version probably does not have the bugfix, Stockfish Dev does, as of tod...
