4.5.4 Join opening book

With this powerful option you are able to join 2 or more MVS opening books into one big opening book! Do you have for example our external 12,000,000 opening moves on the CD-ROM Rebel GOLD? You can join these books into one big opening book. There is just one limitation: Books can not be made larger than the size of the Rebel hashtable. In practice this means that if you have a PC with 8 MB of Ram you are able to make opening books of 5 to 6 MB (!!) This option works as follows:

• Choose from the file menu the book you want to ADD.
• Next choose the book to INSERT the first selected book into.

EXAMPLE
Suppose you want to join the KASPAROV.MVS and the REBEL.MVS main book (available in the BOOKS directory) Do the following:

• choose Join opening books
• select KASPAROV.MVS (after question "Select to add:")
• select REBEL.MVS (after question "Add to:") next will appear:" Add file KASPAROV.MVS to REBEL.MVS?"
• confirm with YES and all moves of KASPAROV.MVS are inserted in REBEL.MVS

REMARK
Take special care about the following: if you make very big books with "Join opening books", the response times of the opening moves will slow down. A fast harddisk and/or a good diskcaching program is very important for using opening books greater than 2 MB.
