if you actually examine the evidence, Playchess draws in B90 are not materially higher than all other lines.  This was a surprise to me, as I used to think like you.  What you propose is intuitive and logical, but the facts don't seem to support it.

B90 has a reputation for being a very sharp opening, so the fact that it has only a slightly higher than average draw rate doesn't necessarily disprove my thesis. Can you give an example of the draw rate for a staid opening that's been played a gazillion times?

While the kibitzers may put a move into book very quickly, they typically do not follow that line until it has been successful several times, and even then the copycats come one by one, not all in a rush.

First, I am not concerned about people copying my lines. I see this as a good thing when it happens (very rarely). I am much more concerned with someone coming up with a drawing line and then having everyone copy it.

Second, there are actually two aspects to how kibizting interacts with .ctg type books and the chessbase gui to affect play. The first is the dissemination of lines, while the second is the tendency for everyone to play the same line (both because they are using the same database of games to generate their books and because of .ctg's preference for playing lines that have been played many times before). Since I play offbeat openings, the responding lines that people pick up and copy tend to be the less sharp and more drawish lines.

Nonetheless if you wanted to start playing Nimzo-Indian I doubt anyone would follow you for many months.

Probably I should work out some kind of arrangement with you to identify openings that are less well developed. Some of these will be more engine friendly than others (but not being engine friendly has its own advantages), but it's always fun to get people out of book early in the game, especially when there is a decent chance of getting into an unclear position.

Examples of these lines?

Most recently, I have been using B27 in my CC games with excellent results. This is somewhat surprising, given that people have figured out how to reduce similar lines that I play in A01 a tempo up to a dead draw.

No, YOU can't do it.

Actually, I've been playing off-the-beaten-track openings for years. I don't do database searches to see what's original and what's not, but there were bound to be a few novelties developed along the way.

Mind you, some top corr players certainly uses those as a reference.

As they would use any engine-engine game.

And I guess engine room also has some influence on commercial books like Rybka books or hiarcs books.

I assume the Rybka and Hiarcs books are over-represented in the openings commonly played in the engine room. I consider this a weakness, not a strength.

Where does it say they are not allowed? There is an upper limit to how many games can be kibitzed in 1 session.

pipper this is a never ending story ....
To see if you understand that we use macros to copy the games is just a matter of convenience and time savings. The same could be done manually.
The few who do, never copy a portion of the book. We only use the databases to query purely statistical. Or really believe that Eros Riccio, Alberto Guecci, or other strong players run are based on games played in Playchess??
On the other hand, is the only way to preserve the rounds, but would be lost forever.
I have a group of players that we exchange the games, they sent me everything they could copy and / or played, and then collect all the games, I will forward a large database of about 40,000 sets monthly.
It is not just a matter of accumulating games, you have to know what to do with them!

pipper esto es una historia de nunca acabar....
A ver si se comprende que los que utilizamos macros para copiar las partidas es sólo un tema de comodidad y ahorro de tiempo. Lo mismo se podría hacer manualmente.
Los pocos que lo hacemos, jamás copiamos una partida al libro. Sólo utilizamos las bases de datos para consulta meramente estadística. O realmente piensan que Eros Riccio, Alberto Guecci, u otros fuertes jugadores corr se basan en las partidas jugadas en Playchess???
Por otra parte, es la única forma de preservar las partidas jugadas, sino, se perderían para siempre.
Yo tengo un grupo de jugadores que nos intercambiamos los juegos, ellos me envian todo lo que pudieron copiar y/o jugaron, y luego de recopilar todos los juegos, yo les reenvío una gran base de datos de alrededor de 40,000 juegos mensuales.
No es sólo una cuestión de acumular juegos, hay que saber qué hacer con ellos!!
