Subject: Kryokov's amazing victory - 6 man EGTB sharing

Hello to you all,

When Kryukov did his post onto the subject of sharing over p2p the 6 men EGTBs,
i must admit i was very sceptical.

http://kd.lab.nig.ac.jp/chess/tablebases-online/

Sharing a terabyte of 6 men over p2p?

Important concerns i had would have been less perhaps, had i known he has grown
up in the same city where Nalimov grew up.

"Omen est nomen",  they say in latin.

The result is by now that over 750GB of EGTBs can be found p2p. Not all EGTBs
found 1 source yet, but that's probably the power of peer2peer. You keep
learning.

Of course some EGTBs are still missing in Nalimov format and not all of them are
online. We have reasons to believe the full set should be around 1.2TB,
of all 3-5 + 33 + 33p + 42 + 42p.

Perhaps Eugene or Bob wants to help out his ex-countryman, completing the set at
Kirills computer to the full 1.2TB, so that at least every EGTB is possible to
obtain.

For now it's clear this project is an overwhelming success.

Of course we can complain about bandwidth and old emule versions which i
disliked a lot and that FTP is a great thing too.

The advantage of emule is that even those who download a little, also help to
upload a little. That's something ftp doesn't help you with.

Of course i can complain that if you already got 600GB at your disk, that
getting that next 150GB is kind of slow, as just a few uploaders have them.

But that's just temporarily. It's already clear that it is a great success.
Because for those who just need a few 6 men of their choice, a few very
interesting 6 men can very easily get downloaded in this way, and that's what
matters for the majority of users.

Want to have KRPPKR or KPPPKB or KPPPKR or KPPPKN or KRPPKQ or KRRPKQ?
All 4 of them real interesting to have during a game as chessprograms make some
big mistakes evaluating those, simply because they are very hard endgames to
judge whether it's a draw, a win or sometimes even a loss, then feel free to go
to that homepage.

Read what to do and easily get them over the internet.

Note that there is in total 510 endgame table bases of 3-6 men. Hundreds of them
can be found online at this homepage.

This is quite different from the past. Bandwidth from commercial or scientific
viewpoint is very expensive. Universities and companies pay deerly for their
bandwidth and budget bandwidth a lot.

Yet P2P beats all that and allows everyone to download from everyone, which for
the future of chess will be a very interesting way to solve the game.
