7. CAT - Computer Analysis Tool

7.1. How can Rebel use the CAT data for its own analysis ?

Open the submenu "Use EOC knowledge" in the Rebel "Options" menu and select "MODERATE" or "STRONG".

• MODERATE
  Rebel will use the analysis of Rebel, Rebel-Tiger and even use the book moves of Fritz and Nimzo for its own calculation. This option is highly recommended in case you have loaded the provided CAT database COMPCOMP.EOC (found in the CAT directory) or REBLEARN.EOC (found in the root directory).
• STRONG
  Rebel will use the analysis of Rebel, Rebel-Tiger, Fritz, Crafty and even use the book moves of Fritz, Nimzo, Shredder, Junior and Hiarcs for its own calculation. In a way (provided you have a huge CAT database) you can emulate the play of all these chess engines. The STRONG setting is not recommended for maximum playing strength. If you use the STRONG option it is advised to load the big CAP.EOC database (provided on cdrom in the CAP directory) of 1,000,000 positions or use the CAT database COMPCOMP.EOC (found in the CAT directory).

7.2. I have imported a lot of games into CAT but I don't see any (new) positions ?

Games must contain computer analysis, otherwise there is nothing to store into CAT.

Typical suited are:

• Output from (any) auto232 games (the SSDF games comes to mind)
• Output from Rebel's engine-engine matches (by playing many matches you automatically make Rebel a bit stronger!)
• Output from the popular ChessBase engine-engine matches
• Using suitable EPD files such as the CAP data from Danniel Corbit
• The output from Rebel's function "Analyze EPD"

7.3. I have analyzed an EPD file with "Analyze EPD" but when I import the data into CAT I don't see the new added positions ?

"Analyze EPD" stores the output in a special file DD-MM-YY.EPD (day, month, year) to secure your data. You should import this DD-MM-YY.EPD file into CAT.

7.4. Sometimes Rebel is busy for 5-10 seconds (or longer) on the hard disk, what is happening ?

This can happen when you have create a big REBLEARN database in your root directory and also have "Learning=ON" (see menu BOOKS). The cure is to clear the REBLEARN database (clear learning) or set "Learning=OFF"

Explanation
When "Learning=ON" Rebel will automatically store analysis into REBLEARN from time to time while you play your games or analyze positions. Its goal is to record every analysis Rebel has made and use it afterwards. When REBLEARN grows and grows the delay will of course grow too.
