CCRL 40/40 - A most curious game

[Norm Pollock]

I guess we don't expect sensations within moves no. 1...3 anyway. 500+ years of master chess practice and analysis should guarantee that, at least...

Rules have changed over the last 500 years, but have been stable for the last 200 years or so. An excerpt from
http://www.ttebooks.com/royalchess/1history.html

Code: Select all

Since then there have been many major changes in the rules of the game.

About the middle of the 15th century, the French made the single most profound change in the evolvement of the game of Chess. They changed the Viceroy from a him to a her, called her the Queen, and gave her unlimited moves in any direction, suddenly making an almost useless piece into the strongest warrior on the battlefield.

Before the 15th century the Bishop could only move two squares diagonally in any direction, and it could jump over any piece on the first square of its move.

In the early 16th century, pawn promotion-allowing a pawn, upon reaching the eighth rank, to be promoted to any other piece of higher powers-came into effect. Originally, the pawns could only move one square at a time, even on their first move. Their main function was to form the "front lines" as in more modern warfare, a place the enemy wasn't to be allowed past.

A pawn became relatively useless if it advanced too far into enemy territory.

But with the introduction of pawn promotion, an increase in the pawn's mobility became desirable. This brought about the two-move rule used at present.

Seeing that a pawn could sometimes use its two moves to pass an adjacent, opposing pawn, avoiding the necessary opposition of the foot soldiers, the "en passant" rule was introduced.

The King seems to have always moved the same as at the present, except that the game used to be played until he was actually captured. Because of the King's vulnerability due to the Queen's enormous scope and power, several methods of "castling" were tried before the 16th century.

One method was to allow the King to move two or three squares on its initial move.

Another method was to allow the King to move directly to King's Knight two.

The present method of castling was introduced in the mid 16th century by a priest named Ruy Lopez.

No,the opening book has a responce against 1. Nc3 but ti's poorly developed,8 halfmoves at best....
Dr.D



I read everything carefuly and that's why I told you that the answer against 1. Nc3 in this outdated opening book is poor....
As for the configuration,yes,he posted the parameters and they are about right...as for the games where the two sides didn't use the opening book,you can terminate Jeorge for this
Dr.D

The problem is that the games that started with Nc3 neither of the engines used a book. (games 1-3-5)

In the games that engine A used a book it was just 2 or moves (2-4-6)
example game 2 d4 g6 Nf3 Nf6 and again white started analysing on his own but the simple c4 transpose to any indian defense (kings indian,gruenfeld, benoni or even a benko) white choose to play Nc3.
game 4 Nf3 Nc6 d4 d5 here engine started 'thinking' before playing c4 where this is just a transposition to the Chigorin defense.
game 6 repeated the moves from game 4.

So either he is using a wrong configuration transpositions unmarked, or he is using a 2 move book. Because even a 8 move book will know that c4 is a transposition to the Chigorin defense or a queens gambit vs and indian set up.

Thanks,that clears things up....the transposition feature is unmarked....

Thanks a lot, that was the problem, forgot to check the transposition feature.

Here is the score so far I will let it run for another 100 games, this time at 10 minutes per side. I still don't think that a good opening book give a strong engine more than 30 rating points, but on the other hand if the opening book has errors like in the game Bright vs Cyclone xTreme, then the engine is better off to play without that bad opening book.

Engine Score Ry Ry S-B
1: Rybka v2.3.2a.w32-B 3.5/6 ······ =1==== 8.75
2: Rybka v2.3.2a.w32-A 2.5/6 =0==== ······ 8.75

[tano-urayoan]

Again Jorge the second game you posted neither (ninguna) of the engines is using a book. There is problem with your tournament set up.

[Mike S.]

He just won't switch off "save mainline". Instead, he switched off "value, depth and duration" now?! And he will get 50 games with 1.Nc3 because no book at all for one side.

Aaaaargh! This is such an unbelieveable ignorance that it feels like a nasty aggression. I'm starting to believe this is inteded, to troll. Can someone really be like that without bad intention?

Annoying to the max.

[pichy]

I think, for this experiment no book at all for one side is not optimal, as we can see from always 1.Nc3 for White. I would use a solid, large book for the other engine, and a short - maybe 3 full moves deep - book, with wide variety, for the "no book" engine. By that, we wouldn't see "engine novelties" earlier than at move no. 4, but 1.Nc3 problems and similar could be avoided.

I guess we don't expect sensations within moves no. 1...3 anyway. 500+ years of master chess practice and analysis should guarantee that, at least...

You are correct at no book at all is only a good option if the the book intended to be used is full of bugs like in the game Bright vs Cyclone xTreme. Now in order to avoid the 1Nc3 for White, what book do you recomend to be used for the short maybe 4 full moves deep with wide variety. Do you have one available at your disposal. For the large one I can always use your most recent Book. If you can email it to me.

I even unchecked the save Main line option by selecting F7 and PGN and Rybka 232a.w32-B is still repeating the 1.Nc3 as its first move for white.

You are correct at no book at all is only a good option if the the book intended to be used is full of bugs like in the game Bright vs Cyclone xTreme.

Harry's book is actually a very high quality book, so you shouldn't be throwing around unnecessary remarks that sully his reputation.
I challenge you to go through his HS-10moves.abk book and post all the bad lines that you can find. I have never come across a line as bad as this one previously, so I'd say you'll be struggling.
You can also go through all the CCRL games played with this book and check the openings if you're so interested in looking for ammunition to damage his reputation. I can assure you you won't come up with much either way.
There are no perfect opening books, but I'll repeat my assertion that Harry's are among the very best. I have no qualms whatsoever about using them. I know that many of the CEGT testers share this opinion. The game posted is a one off.

Graham.

How can you delect the bad lines found in the game Bright vs Cyclone xTreme. Do you have a clean or filtered HS-10 moves.abk

No idea how to this. I just use the books, not make them or investigate them. Sorry.

[Guenther]

Following the games you posted there is a problem. In the first and third neither engine is using a book. In the second and fourth one the book was just 2 moves.

You should check your configuration for this test.

He's using the right configuration but unfortunately his test shows no sense as every time Rybka plays 1.Nc3,there is not much to be answered with....
Dr.D

Do you mean the used book has _zero_ book moves against 1. Nc3?
Well he could have noticed this already in the second game then ;-)

Guenther

No,the opening book has a responce against 1. Nc3 but ti's poorly developed,8 halfmoves at best....
Dr.D

I downloaded the Rybka.abk and looked it up now. You are wrong
and this book has _no_ move against 1. Nc3!
(No matter if min games is set to 1 or >1)
Thus you two times made a wrong answer here despite my questioning.

The case is closed now. There were two setup problems.
a: Jorge did not check the transposition box
b: He used a book which does not cover 1. Nc3 at all

Thanks to Tano and Mike for trying to clear up this mystery.
