I think for this test are preferable drawn positions. Here is a study by Akobia+Becker 2005 [D]8/8/6p1/7R/b6K/5k2/3n4/2n5 w - - 0 1 bm Rh6=

And I add the next one by Kekely 2003

Thanks Mario! And welcome to the forum!

I will try to analyze your positions when my computer finishes current computation. Looks promising!

Re: EGTB Testsuite

Here's traditional position to test, if 4 piece tb/bb access is working in the search:

[D]8/k7/8/2R5/8/4q3/8/4B2K w - - bm Bg3

Other moves lose I think. Actually I have seen solution without bases, but
it took a lot time. With bases You got solution instantly.

Can you test this one?
[D]8/8/1P3k1r/8/2K1b1P1/3R1r2/7b/4N3 w - -
IMO the best move is Rxf3 and probably draw in BB:N ending due to 50 moves rule.

I analyzed these two positions and added to the collection with my comments. First one is "imperfect test", second is "possibly useful". Thanks!

Thanks and congratulations! Because as far as I understand we got our first perfect test position! Added to the list.

Solution of a perfect endgame test should not depend on a 50 moves rule, otherwise not all kinds of tablebases can be tested. Glaurung 2.0.1 finds 1.Rxf3+ in 0 seconds (without any tables), I did not check other engines. Thanks anyway!

Re: EGTB Testsuite

Many of these will qualify (from an epd test set called pawntest). I guess that about 1/3 will meet your criteria. I will leave it to you to filter out the ones that you want.

I suggest also a basic test where all the answers are known and can be found by direct lookup, just to validate that the tablebase files are working.

Code: Select all

6B1/1pp3p1/3p4/n1k2P2/2P3P1/4K3/8/8 b - - bm Nc6; id "Koundinya Veluri, 9/25/2001@22:56:30 on CCC";
