Re: Is there anymore unsolved positions at all!?

Forget fastest mates only best move is interesting now. With monster hardware / special engines and/or multimove mode are all positions published here solved? I don't remember lately any unsolved. This one comes to mind: rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1 This is not a good po...

Re: Polish users cut off from TalkChess

If people want a free VPN to access Talkchess I recommend SoftEther VPN, I've been able to use it to bypass blocks of videos in my country, and yes, when you can watch videos it's because it's very fast and transparent. What components are you meant to download? https://www.softether-download.com/e...

It is difficult to deduce what his problem is, as what he writes is self-contradicory. He doesn't disagree with the number, but with its value... What the heck does that mean???
I assume it just means the model is wrong. So while in theory it is 1/256. In practise it is much lower.

Do you actually believe in a file of 8 million games with 8 wins and no losses that the 8 wins are not statistical noise?
Not been following this properly but in your opinion what is the maximum amount of games that you can have for the 8 wins not to be statistical noise?

Re: What is the best way to obtain the 7-piece tablebases?

So RAM cost will dominate when it becomes feasible for ordinary {albeit a bit nuts} humans to do it. I might even be able to give it a go. But who knows. The only people who are a bit nuts is the government for not spending a paltry million dollars for a stunning 8 piece database. If you do it, you...

You don't need enormous ram to use the tablebase files.
You need enormous ram to build them.
But even accessing 8 men files, you will need a lot of RAM.
Either that, or there will be a speed trade-off.
and by a lot of RAM to access 8 men files do you mean many TBs of RAM ?

Re: What is the best way to obtain the 7-piece tablebases?

Around 2,000 TB of disk space would probably be enough to store the full 8-piece set (WDL+DTZ). Today, storage is $20/TB https://edwardbetts.com/price_per_tb/ So only $40,000 for the disk. Server memory currently runs about $10K/TB (unless you need the greasy fast stuff) $640,000 for RAM. In five y...
