STS (v3.0) - Knight Outposts/Centralization/Repositioning

[swami]

Chapter 3 Of the Strategic Test Suite: Knight Outposts, Centralization and Repositioning is now available for download.

* Consists of carefully selected 100 questionairres on Knight OutPosts/Centralization/Repositioning

* All of the questions in this test suite are selected by me and thoroughly verified by Dann Corbitt. Each question has been analysed by top engines for hours.

* All the answers carry similar traits:

• (1) A Knight move to take control of the center or posit itself in the center. (Centralization)
  (2) A Knight move to step back and reposition itself to lead the different (or better) path. (Repositioning)
  (3) A Knight move to take control of the opponent's weak squares (Outposts)

I initially selected about 190 problems and sent them to Dann, of which 100 has passed criteria. Dann made the final selection and done all that analysis with the help of the engines.

Recommended time: Anywhere between 10 seconds - 2 minutes for each test.

Thanks, as always, Matt. Looking forward to the results from Moneypenny on this one.

I hope it fares better on this than it did in the previous two.

Are these positions taken from top GM play and are they annotated?

Hi Terry, Some of the positions are taken from Top GM annotated games, and most of the others are taken from engine games from either Rybka, Deep Fritz, Shredder, Naum, Thinker and Zappa. All the positions have been given a green light by atleast 2 top engines agreeing simultaneously in Dann's tests- giving difference of signficant +0.25 - 0.50 between the 1st and the 2nd best move after nearly 6 hours of analysis for each position.

Most of them are strategical in nature, none of them are tactical as far as I know.

Chapter 3 Of the Strategic Test Suite: Knight Outposts, Centralization and Repositioning is now available for download.

* Consists of carefully selected 100 questionairres on Knight OutPosts/Centralization/Repositioning

* All of the questions in this test suite are selected by me and thoroughly verified by Dann Corbitt. Each question has been analysed by top engines for hours.

* All the answers carry similar traits:

• (1) A Knight move to take control of the center or posit itself in the center. (Centralization)
  (2) A Knight move to step back and reposition itself to lead the different (or better) path. (Repositioning)
  (3) A Knight move to take control of the opponent's weak squares (Outposts)

I initially selected about 190 problems and sent them to Dann, of which 100 has passed criteria. Dann made the final selection and done all that analysis with the help of the engines.

Recommended time: Anywhere between 10 seconds - 2 minutes for each test.

Feel free to report the results from your engine/ favourite engine, suggestions are welcome.

Special Thanks to Pedro Castro, Allard Siemelink, Zach Wegner for the testing and correcting mistakes throughout the process. And Thanks to those who reported bugs and tested out the V 1.0 of the test suite called "Undermining", and v2.0 called "Open Files and Diagonals".

And Extra Special Thanks to Ulysses for creating the beautiful logo!

Test Suite Released time: 3rd of June, 2009
Swaminathan and Dann Corbit.

I ran a quick test with the following details:

10 seconds per move.

I told Crafty that if it produced the same (correct) move for 5 consecutive iterations, to consider this one done and move on to the next position. That speeds things up quite a bit although I can run without it if it matters.

Here's the results:

Code: Select all

total positions searched..........         100
number right......................          96
number wrong......................           4
percentage right..................          96
percentage wrong..................           4
total nodes searched..............  1430919140
average search depth..............         8.1
nodes per second..................    15638460
total time........................        1:31

Crafty missed #13 (chose Nd5), #17 (liked Ncxe4), #57 (likes Qg6), #93 (likes Nd5)

Ran it again at 30 secs/position, but had to keep correct move for 6 iterations before stopping. Got 97 out of 100. Picked up #93...

Why I asked is Night play is the trickest and my favorite weapon!;)

The GM samples with annotation would be nice to look at and compare them to machine analysis as well as compare them to engine vs engine and how it corralates with GM play and analysis.

Crafty seems on par with Rybka for this test set.
It seems that Crafty has excellent knight understanding.

Or Bob has an ultra-superior hardware at his disposal. Let me run to see how Crafty does on my Core2Quad...

Thanks for the test run, Bob. That's very impressive result, may I know what hardware was used?
