You can download the book I used with rybka 2.3.2a on my site. The book isn't as good with rybka 3, but it is still a decent book. It plays sicilian lines. Link is in my sig.

Hi Moheevi,

I'm interested in how you apply learn from database from your learn base of games.
Do you tick all 4 and do one big learn -white, black, win, loss - or just wins, and if so do you do white wins and black wins separately (in which case would need separate game databsaes) or all wins together?

From the Fritz manual:

Learning from a database
With this function the program learns from the experience of other players. It looks at the games of a database and pretends it has played them itself. On the basis of the results it changes the weights of individual variations. Edit – Openings book – Learn from database displays a dialog box in which you can set a number of learning parameters:

Wins: Only won games are used, the program increases the weights of white moves if White won and black moves if Black won.

Losses: Only losses are considered. If White lost, the white moves are reduced, and if Black lost, the black moves are reduced.

White: The program evaluates the games from the point of view of White only. The weights for white moves are increased if White won, and decreased if White lost.

Black: The weights for black moves are increased if Black won, and decreased if Black lost.

Player: Only considers the games of one specific player in the database.

These five options can be combined in any way you like. You can also restrict the import to a certain number of games in the database by selecting "Games" at the top of the dialog box.


Thanks,

I put all the wins in 1 database and use wins, white, black. Sometimes I experiment and do just wins without white and black checked.

[goldminer999]

Does anyone know whether Magister 2.ctg is available from anywhere ?

Thanks
