3 games Toga 1.4.1SE (e3) vs. Rybka 2.3.2a MP on Playchess.

[Edward German]

I played with Toga on a Core 2 Duo 2.66 GHz and with 256 MB Hash. Rybka played on 4x 2.4 GHz Quad. Timecontrol was 16m + 0s.

Toga 1.4.1SE (e3) played with this Settings:

[OPTIONS]
Verification Reduction=4 (Default = 5)
Toga Lazy Eval Margin=225 (Default = 200)

In the first game, I think that Rybka stand better after the opening, and for black was here not easy hold the game. Rybka won nice! Then in the games 2 and 3, Toga played very well and hold two nice draws. I am very pleased with the play of Toga 1.4.1SE (e3).

A good game by Toga 1.4.1SE!

[Golem]

Interesting result, I will try your settings at blitz games as soon as I have finished testing the 1.4.1SE default version.

[Edward German]

Interesting result, I will try your settings at blitz games as soon as I have finished testing the 1.4.1SE default version.

Thank You!

It is possible that on Bitz perhaps the default-setting are a little bit stronger, then the default setting is a little bit faster.

In my opinion, my setting should be stronger at timecontrol 15m --> or longer timecontrols. My 3 games against Rybka, I played on timecontrol 16m + 0s.

But we will see, nothing is inpossible.

My thanks in advance!

Hello Eduard,

Good to see that there is no more Toga King Safety necessary in your e3 settings. But I was wondering Eduard whether you checked your Private Messages already as it seems Denis has not had a reply yet?

Hello Eduard,

Good to see that there is no more Toga King Safety necessary in your e3 settings. But I was wondering Eduard whether you checked your Private Messages already as it seems Denis has not had a reply yet?

Hello Eelco!

OK now it is out.

Yes, Yesterday I seen a pm of Denis. He created me a private Toga II 1.4.1SE_nemeth Engine. Many thanks to Denis again! I am very happy!

I would not post about that.

Of course I played with my private Toga II 1.4.1SE_nemeth on playchess.

Here my installation under Fritz:

[ENGINE]
Name=Toga II 1.4.1SE T2e3
Author=Thomas Gaksch and Fabien Letouzey
Filename=C:\Programme\ChessBase\Engines\Toga141se_nemeth\Toga141SE-nemeth-2cpu.exe

You see that here is a new Engine Toga141SE-nemeth-2cpu.exe.

Denis modified here this two parameters

Verification Reduction=4
Toga Lazy Eval Margin=225

and sent me a private message with a download link, only for my private Engine of Toga.

I will not post this download Link , then I have saved my engine on a CD ROM, that is enough.

If I play on Playchess, then You can see on screen only the name "Toga II 1.4.1SE T2e3" and the Server save the game too with this name.

On my PC-Screen of course I can see more, that:

Toga II 1.4.1SE_nemeth T2e3

OK, nice, I have now a my private Engine of Toga 1.4.1SE (Single and 2 CPU). . Thanks to Denis Mendoza for the compile!

My best wishes!

[Edward German]

My first Blitz Games with Toga II 1.4.1SE_nemeth (read about my post before).

Filename=C:\Programme\ChessBase\Engines\Toga141se_nemeth\Toga141SE-nemeth-2cpu.exe

For "Playchess" Server-playing I called the Setting Toga II 1.4.1SE T2e3.

Denis Mendoza compile the Engine (privat only) with this Parameters:

Verification Reduction=4 (Default was 5)
Toga Lazy Eval Margin=225 (Default was 200)

I seen in my Nemeth-Toga-Engine more parameters then in original Toga II 1.4.1SE, but I think that the other Parameters are egual with the original Setting.

I played on Core 2 Duo 2.66 GHz.

Of course all game was live and with Permanent Brain (for me is PB important !).

I played one game against Zappa Mexico II, and two games against Fritz 10, Blitz 5 games - my Nick is Solist.

PGN before few minutes on Playchess:

I belive that Toga II 1.4.1SE_nemeth played not bad.

[Edward German]

I played (on Playchess) with only an Core 2 Duo 2.66 GHz. Both games was played before few minutes on Playchess.

First game I lost on the fast Blitz Timecontrol 3m + 0s against an strong Naum 3 (Quad 2.4 GHz):

An fantastic Blitz-Game 3m + 0s by Toga II 1.4.1SE_nemeth (on 2 Cores) against an super strong Rybka 2.3.2a MP (on Extreme CPU X9650 @ 3.00GHz 4007MHz, 4 threads)!

My special thanks to Denis Mendoza for a very fast compile of Toga II 1.4.1SE_nemeth! Yes my engine playing very fast and go very depth.

I am high belighted!

Viele Grusse, Eduard

Your newly tweaked Toga sounds interesting. At longer/standard time controls, how much stronger do you estimate it is versus the default settings?

I test engines at extra-long time controls (usually 40-moves/3-hours). While I get good information that way of the strength and characteristics of various engines, the long time controls means that tournaments take a long time and so I have fewer games to analyze.

So far in two tournaments that I've run, Toga II 3.1.2SE has surpassed Toga II 1.4.1SE, both playing with the same book. The other engines were: Rybka 2.3.2a 32-bit (the victor in one and third place finisher in the other), Strelka 2.0B (second place finisher in both - playing with the same book as the two Togas), Glaurung Lodz 2007, Rybka 1.2f 32-bit, Rybka 1.1 32-bit, Fruit 2.2.1, Naum 2.0, Shredder 9, and Spike 1.2 Turin. Shredder and Spike were the bottom two finishers in both tournaments - alternating places. Toga II 3.1.2SE won the first tournament.

I should mention that the Togas and Strelka all play with a special book that I've composed. I'm a correspondence chess player, so I've created a book of the lines that I play, plan to play, or am interested in testing. In this way, I learn about the various engines while also testing my openings.

That said, I've only 20-games of tournament experience with the default Toga II 1.4.1SE, but its results haven't been impressive relative to other engines. So, I'm interested in testing your settings in the future, Eduard. Unfortunately, time is limited for the next few days.

Auf wiederschreiben!

I'm a correspondence chess player, so I've created a book of the lines that I play, plan to play, or am interested in testing. In this way, I learn about the various engines while also testing my openings.

That is an interesting remark for programmers and book editors.

That is exactly what I mean when I am sceptical about intensively engine-tuned, narrow books. I mean, in contrast to books which serve the purpose of playing the engine's preferred openings, instead of the user's preferred openings (or a solid and wide 'general' repertoire) and also keeping in mind that not anybody can or wants to create his own books.

The obvious idea is that TWO books are required:

1. solid, wide 'general theory' representation for the chess player
2. tuned engine book as best support for computer chess competition (only)

Hi Mike,

You raised some wonderful issues. I think there are corollaries to this as well:

1) How objective are the results of my tournament games when engines play with different books?

2) Did I match the books to the engine's properly?

Here's what I've done. Whenever an engine comes with a book, then I always use that. Engines without books are given one that I've created, based somewhat upon my perceptions of the engine's strengths/weakness and partly upon what I want to test.

For example, I've noticed that Fruit 2.2.1 does surprisingly well with hypermodern defenses, such as the Modern, Pirc, Benoni, and King's Indian, etc. So, it got a book with those lines as Black.

Then, when the tournament games are examined, I check to ensure that opening book errors are "fixed" by inputting better lines. I do this for all books.

As for the book of my openings, I want objectivity. I want to find out in advance if my ideas are any good...rather than learning the "hard way" in a correspondence game. So, it made sense to me to give it to an engine that's neither the strongest nor the weakest. Afterwards, I always evaluate the openings with my chess skills, with my opening reference materials, and with a variety of engines. The opening book of my ideas is generally a "narrow" book. I often find that the book leaves off in positions that the engine doesn't understand (e.g. I've yet to find an engine that deals with IQPs properly, or knows how to handle "hanging pawn" structures), so I've continued the book well beyond these positions in order to reach positions the engine handles better.

Does my book confer an advantage? I think it's generally superior to all other books I've seen, including RybkaII's excellent book. But, I'm generally a technical (read: positional) player, while engines prefer open tactical positions where calculating can be done with less emphasis upon positional details or endgame prospects.

Finally, regarding the issue of narrow books versus broad books, there is a difference. If a narrow book is objectively strong AND tuned to the engine, then it's ideal for winning results. Broad books are probably written for commercial reasons, to appeal to a wide market that demands variety.

One example of broad books is Shredder's. An example of a narrow book is Junior 9's. The latter is a terrible book that seems neither objectively good, nor tuned to the engine. For example, why force Junior to play the Four Pawns attack against the King's Indian and the Saemisch Attack against the Nimzo, without giving it good lines, and deep lines, to help it? Instead, the book usually just ends abruptly in bad positions.

Sorry for rambling, Mike.

All the best,
Steve
