Information for users of the chess program Queen
================================================
By using a text editor, such as Windows Notepad, you can specify some data for Queen:

1. The hashtable size.
2. A directory containg the Nalimov endgame table bases
   (egtb) files;
3. The path of an opening-book file (wbqbook.bin).
4. A resign threshold.
5. An indication not to use an internal book for openings.

For example, queen.ini can have the following contents:

   ht 16
   egtbdir d:\tb
   bookfile c:\mychess\wbqbook.bin
   resign 1200
   nointernalbook

In this example, the directory \tb of drive d: is searched
for the Nalimov egtb files, and the external opening book
wbqbook.bin will be used if it is found in the directory
c:\mychess.

The lines in the file queen.ini can appear in any order,
some of them may be omitted, and the text is case
insensitive. If no opening book is specified, the
the file wbqbook.bin will still be used if it is found
in the current directory. If that is not the case either,
only a smaller internal opening book will be used.
General format of the file queen.ini:

   ht <size of hashtable in MB>
   egtbdir <absolute or relative directory of egtbs>
   bookfile <absolute or relative pathname of opening-book file>
   resign <threshold for resigning, expressed in centipawns>'

Optional:
   nointernalbook

If you omit the last line, Queen uses its internal book, possibly in addition
to the external book already mentioned.

Note that 'egtbdir' is followed by the name of a directory,
while 'bookfile' is followed by a complete path name, including
the file name (usually wbqbook.bin).
Here is another example:

   ht 64
   egtbdir nalimov
   
With this queen.ini file, 64 MB will be used for the
hashtable, the subdirectory nalimov of the current
directory will be searched for egtbs, the current directory
will be searched for the file wbqbook.bin, and the default
resign threshold of 1000 will apply.

If the file wbqbook.bin is supplied either in the current
directory, or in a directory specified in the file
queen.ini, it will be used as an external opening book;
otherwise, only the more limited internal
book will be used. (This internal book will also be
used if the external book is available but a probe
into it failed.) It is recommended to use the external
opening book. Download the file wbqbook.zip
from my website and unzip it to obtain wbqbook.bin.
This file is in binary form. I am grateful to Carlos
Pesce, who sent me some files on which this external
opening book is based.

The defaults are as follows:

   ht 8
   egtbdir tb
   resign 1000

In other words, the default hashtable size is 8MB, the
subdirectory tb of the current directory will by default
be searched for egtbs and Queen will by default resign
if it is at least 1000 points behind (both in purely 
material and in overall score).
