Read that over and over again.

Where do you see the word tablebases in there?

I'm getting tired of this also. It's not allowed. Live with it!

Endgame tablebases are not allowed at RHP.

See page 1 of the link I posted.

Do a Google search with "endgame tablebase". Get plenty of relevant sites using this term? Yes.

Do a Google search with "endgame database". Get plenty of relevant sites using this term? Yes.

So both the terms "tablebase" and "database" are widely used. And it doesn't matter if one is more common or correct than the other, both are common usage.

No worries... but I guess I can just use the following site:

It does say *database* doesn't it? So must be ok?! ;-)

The point of them is to give you an advantage while you have it, much like an opening book.
EGTB's do give in-game status information. They'll show you how many moves are left until the game ends, with best play.

They are accurate 100% of the time, if generated properly. The fact that some winning positions can't be realized due to the 50-move rule is irrelevant. In this case, the EGTB has proven that the ending is a draw due to the 50-move rule.

"Furthermore, egtb's are good only for 3-4-5-6 pieces. After you get to one or two, you are on your own."

You can never get to one, and have a draw with only two, because they're both Kings. 😛

"The point of them is to give you an advantage while you have it, much like an opening book."

No, they give you a guaranteed result. That's far more than any mere advantage.

Alas, you are right. I shall therefore limit my answer to this:

I’m one of the game moderators (and can therefore speak on behalf of the site admin on such matters) and can confirm that endgame tablebases are definitely not allowed.

My colleague, Gatecrasher posted the following in a thread in April this year: Thread 40977

“A database, for the purposes of the Terms of Service, should consist of previously played games only. An endgame tablebase, i.e. Namilov, is not a database under this definition. Using an endgame tablebase to assist you in a game is cheating and a violation of section 3(b).

- The Game Mod Team”

Gatecrasher explained in great detail the reasoning behind this decision.

I think it would be very helpful if the TOS was updated in order to state explicitly that endgame tablebases are not permitted.

Agreed, except I'd say it's a *necessary* update to the TOS. If the TOS doesn't get updated, the issue will remain.

Well, I'm not going to disagree with you. Russ should have amended the TOS a long time ago.

Incidentally, he should also put in a line warning against the discussion of games in progress. A lot of people post their in-progress games in the forums, asking for advice, without realising that they're breaking the rules.

I agree, but there is an issue - I have John Nunn's secrets of Rook endgames, which was written by "data-mining" of endgame tablebases (EGTB). Now, it is clear that use of EGTBs is not allowed but the use of Nunn's book is. Most of the time there is not an issue - Lucena's position has been know for centuries - but some of the others in the Nunn book have not. The book, entirely about K+R+P v K+R, contains best lines that a player should be free to use here - unless you want to include results of data-mining as forbidden material - and, although there are plenty of K+R+P v K+R positions which don't appear in Nunn's book, hitting a line in the Nunn book is indistinguishable from using an EGTB. Unless you intend to check every relevant position against such texts it is going to be hard to distinguish cheating from legitimate research.

Although I will add that I recently downloaded about 1.6 Gb's of EGTB's (out of 7.3 Gbs for the full set of 3-4-5 piece EGTBs) I tryed to analyse my own endgames from them and discovered that I'd hit EGTB positions (that I have) in less than 50 (guesstimation) of the 1000 odd games I've completed on this site so they are only directly relevant for around 5% of games.

These things do have legitimate uses though; I watched the K+B+N v K longest checkmate a couple of times and then set SCID's EGTB window to training mode, and - after a number of false starts - now have a good chance of executing the mate in the unlikely event of it ever occurring.

Yes they are computer generated, but nowhere does it say "computer generated databases arent allowed". I could use a general database from engine-engine games, and no one would complain about that.
Even the strongest engines totally foul up the opening if left to play them on their own, engine - engine games will always follow human generated lines in the opening. There isn't yet such a thing as a machine generated opening database, which is not the case with EGTBs.
