Question regarding Shredder 13 GUI

[Amstaff]

Hello, I am a long time user of the Shredder UCI (now version 13). I recently went to change some book options but
that window is now greyed out and won't allow me to make changes.
It's probably something simple that I have forgotten. I haven't done this in a while, but I don't remember having this problem before.

Thanks in advance for any advice,
Gerald

Hi Gerald,

I'm not sure about it. Is the book loaded by the GUI? My Helpfile for Shredder 11 says use Ctrl O, or if there are book moves displayed you can use Right Click on your mouse -at least I think so?- to get the context menu.
Trying this out now, no book moves are visible because not playing a game, but I get there with going to Extra (at the top of the GUI window) -> Options -> Book Options

This is in the Help File:

Book options

With this function the opening play of Shredder can be influenced. You can open the dialog from the context menu of the moves window if it is currently displaying book moves or by pressing Ctrl-O.

Use Opening Book

Defines if Shredder is using the opening book.

Use Engine Book

Activates a special opening book of the chess engines which is used by some engines. In the Shredder engine the opening book is handled by the GUI, therefore you cannot activate this feature with the Shredder engine.

Book Mode

You can assign a value from a-g to every move in the book. "a" moves will be played often, "e" moves seldom and "f" and "g" moves never.

In tournament mode Shredder is only playing "a"-"c" moves if there are some. In standard mode he is playing "a"-"d" and in wide mode also "e" moves.

Book Learning

With book learning the program remembers whether the position after the book was good or bad and is trying to repeat the good ones.

Result Learning

With result learning the program remembers the results of the played games and is trying to repeat the successful opening lines.

Move Values

When selecting a move from the book Shredder obeys the "a"-"g" value for every move.

Use Statistics

Shredder uses the statistics in the book when selecting a move from the book.

Refutations

Takes care of possible refutations in the opening book.

Example: A move was played 1000 times and has a winning chance of 60% but almost all of the last games were lost. So probably a refutation was found. Shredder discovers that and is correcting the winning percentage for this move automatically.

Book options

Classic/Modern

Specifies if Shredder should play rather old openings or new ones.

Requirements

Here you can define which requirements are needed if Shredder should play a move out of his opening book. Shredder will only play a move if at least "Games" games were played with this move of which "Wins" games were won. With white the winning percentage must be at least "White's Score" percent and with black at least "Black's Score" percent.

Move No.

Plays at most "Move No." moves out of book.

Influence

Here you can set the weight of all factors.

Example: If you set the "Move Value" slider to the right, a move with an "a" score will be played even more often and if you set the slides "Num. Games" to the left it doesn't matter much if a move was played 10 or 1000 times.

My issue with that GUI is that it won't stick with the tablebase paths that I give it.
