Testing Horvath programmable feature settings
 
Hi all,

A few weeks ago our French forum member Tibono posted on Hiarcs about his work on the programmable features of the Krypton/Systema Challenge.
As mentioned previously, I am also very interested in this Horvath program and used the setting "All feature-values 20" in two user tournaments, one with the CXG Sphinx Concerto, and one with the tuned Krypton Challenge.
I have been thinking about testing with different settings, and now Tibono comes up with a well motivated new setting. So I decided to go for a number of testgames.
With my "all features 20" setting I got reasonable results against the Saitek Turbo Advanced Trainer and the Simultano. So I think that with the right settings it might be well above the 1800 (active) elo. And I chose the Rebell 5.0 with elo 1872 as its first "victim" ;).
According to the Aktivschach_Elo_Liste_2017.pdf the Rebell played 23 games against the Challenge (+ 11,= 6,- 6). Let us see what happens...

NB: As Tibono's English is better than his German, I will do these posts in English, also taking account the possible USA followers.
NB2: I forgot to mention that all games are played at level 30 secs/move, unless otherwise mentioned.

Best regards,
Paul

Game 1: White plays a rather passive opening, and while trying to compensate for that, one of it's rooks goes astray (19.Rb5?), and has to trade it for a bishop. Black has no trouble in converting the game to a win.

Game 2: In the battle for the center, white makes a tactical mistake with 16.Nce2? And after another suboptimal move (19.Ne6?) the material loss becomes even more. Black continues with risky play to get more advantage, but succeeds.

<b>Game 3:</b> At move 15 white fails to move 15.g4 or 15.Ne2 which both lead to win of a pawn. Now the interesting game stays equal, with at the end black in the lead. But this endgame is too difficult for both (also for me to judge...). Black seemed to have the best chances, but white failed to get a draw by playing 66.Kh4?? instead of 66.Kf5...

<b>Game 4:</b> White treats the Grünfeld opening too risky, with his king left in the center. Black wins a pawn and then has two free pawns on the queen side. He has clear winning advantage, but makes it still a little difficult for himself. But in the end there is a deserved win.

<b>Game 5:</b> Both are out of book very early. The game develops to a closed position, the first pawn exchange is at move 26. It seems to end in draw by move repetition, but the Challenge avoids it because it evaluates its position as a little better. The risc-taking is then punished by the Rebell with 55... Qe4! and white is in trouble.
The funny thing is that the Challenge evaluates its position about -0.3 to -0.4 until 63... exf2. Probably a horizon effect?
<b>General remark:</b> A problem (bug?) I saw before: even when it thinks it has the slightest advantage, it tries to avoid move- or position-repetition at almost all cost, and so deliberately makes a less good move that sometimes even leads to a loss.
On the other hand, I also saw games where some kind of self-learning developed: when one way of developing the advantage got stuck and move repetition threatened, it tried another one, until it did find the winning strategy.


<b>Game 6:</b> Again both are early out of book. Black handles the opening phase a little better, but the game stays rather equal till move 30. Then white makes two weak moves, and black suddenly starts a decisive attack with 32... Dc2! White must lose material, but with 33.Kg2 he chooses again not the best move, and 33... Ng5 immediately decides the game.

<b>Game 5:</b> The funny thing is that the Challenge evaluates its position about -0.3 to -0.4 until 63... exf2. Probably a horizon effect?

Hi Paul, this is a much typical weakness... game 5 illustrates perfectly a comment I made on my webpage:
Code:

"and despite the H8 speed, its tactical ability is limited.
Analysis modus enables displaying the on-going evaluation; noting a late score impact from a position is not uncommon,
compared to its roughly same level computer opponent, displaying the impact a couple of half moves sooner.
This is especially true during endgame, the Challenge does not anticipate enough pawns running for promotion.
Some dedicated code is surely lacking in this area; in addition to a quite pronounced horizon effect at short time control."

And I am afraid tuning any setting would not solve this, the program does not seem to be much selective (unlike the Grenadier: you can largely have some drive on the variants it searchs, thru changing the evaluation function).
Kind regards,
Eric

For these two games I deliberately kept pressing New Game until they opened with e2-e4.
Game 7: A long and hard fight. Black deserved to win, tried everything, but white (the Krypton Challenge) escapes with a draw and a blue eye ;).

Game 8: Rebell playing with white misses 17.f5! with great advantage. After that, the Challenge plays well and wins.
And so the Challenge leads unexpected with <b>4,5 - 3,5</b>.

Hello,

to share more illustration of the resulting playing style (Tibono setting), here are 4 games I selected out of eight the Systema Challenge played, opponents being:
Code:

S.C vs Tasc The Final ChessCard : 0,5 - 1,5
S.C vs Mephisto IIIS Glasgow    : 1,5 - 0,5
S.C vs Fidelity Designer 2100  :  1  -  1
S.C vs Saitek Stratos (B)      : 1,5 - 0,5

15s/move games, free openings. Opponents being all CB-Emu entities.

Within my private Elo-liste, the Systema Challenge entered the tournament with 1789 elo-points, opponents average was 1788 (so, quite well balanced), and 56,3% success rate achieved by the SC is worth a 1832 performance that will slightly raise its ranking.

Analysis with help mainly from Chess Game Analyzer v 0.12 (Ferdinand Mosca) + LC0, NN LD2, 30s/move
Now, the floor is to the games:

AW: Testing Horvath programmable feature settings
 
Hi Eric,

Hans-Jürgen (CC 7) sent me 20 games he played at 30 secs/move between the Krypton Regency and the Rebell 5.0.
These games were also used for the Aktivschach_Elo_Liste_2017.pdf.
The Regency played with the default feature settings (all values 10). He also marked the last bookmoves in each game.
So in the coming time I can just replay those games with your settings (and maybe also a number with mine) to see what the differences are. That saves a lot of playing time for me! :D

Lots of information coming through...

Best regards,
Paul
