[STS v13.0] - "Pawn Play in the Center"

Post by swami » Fri Oct 08, 2010 4:38 pm

Version 13 of the Strategic Test Suite series is now available for download.

* Consists of carefully selected 100 test positions on "Pawn Play in the center"

Information:

Pushing a pawn to the center of the board in early middle game to late middle game.

4 central squares (e4,d4,d5,e5) are the most important squares on the board. It's obvious one has to take control of them before their opponent does.

Tests engine's strength on Pawn structures, Defense, Piece Activity evaluation, King safety, Center Play and mobility.

Key Characteristics:

* Pawn Preponderance in the center.
* Idea is to have more influence in the center, which in turn yields better mobility.
* Pawn moves in center exerts pressure on other side by threatening to open up the file.
* Trying to open up the center reduces the amount of pressure on the flank, and divert's opponent's attention away from the king side especially when he's in the process of setting up an attack.

At 10sec / move, Plisk 0.2.7 (which is not out yet, I am preparing a release soon) found 64/100 with a total score of 726/1000.

EDIT: forgot to mention 1 thread, 32bit on a (old, the very bad one) Pentium 4 @ 2Ghz, Linux.

The first testposition is probably mainly positional because the final score is very close to zero. But it may still be an important move. This one was difficult for Rainbow Serpent because it was search that had to provide some positional knowledge, and finding 1. e4 here took about 8 minutes:

I don't really believe in taking out knowledge from the evaluation function just because it is difficult to prove that it helps especially if the testing is at short timecontrols measuring elo. Taking out missing knowledge that you know does help in certain positions will just mean you create "holes" in the search that will hurt more when the quality of the game rises i.e. at longer times, better hardware, or better opponents. The knowledge should not be too costly to compute of course and not be superfluous but at least the former is something that can be determined without playing many testgames. The latter is much much harder.

So I tried to put back in some knowledge about connected Rooks because the Rooks seemed strong on the d-file here, no need to play 1... Re8, at least I could not see why that would be positionally good. The knowledge was easily copied from Ancalagon (Stockfish 1.7 modified) although I think I discovered a bug there which was quickly changed in this new version for Stockfish 1.8 and behold!, it helped in finding 1... e4 :P

Thanks for the tests!

Anyone is welcome to post the results from any engines. It would be interesting to know how STS 13 rates in terms of difficulty relative to other EPD's.

Interesting read, thanks Eelco.

All of these positions are "balanced Ie Same number of pawns in each side.
That way, advancing the pawn to the center would play greater role and have better impact.

Thanks Swami for this new test.

For Simplex 0.9.6 sts13 10" :62
The rest of the serie:57,48,54,55,68,56,53,44,39,67,46,49
The average is: 53

STS 13 is on the _easy_ side.

Thanks, Antonio. In my tests, It appears that certain engines find this one easier, while others find it in moderately average range. So we can assume that difficulty is somewhere in between.
