Subject: Hashtable Limit/Setting/Default questions - Fruit & Toga II type engines

Author: Stephen A. Boak

I have several questions about setting/saving hash table size (and the max HT
size) for Fruit and Fruit-TogaII engines.

1. What are the Hash Table size limits (if any) for the following engines?

Fruit 2.1
Fruit 2.2 (Commercial)
Fruit 2.2.1 (Commercial)

Toga II 1.0
Toga II 1.0Beta 2
Toga II 1.0MV.6

I normally use the free or demo versions of the above engines under
Chessbase8.GUI (not the latest Chessbase9 GUI).

I also have and sometimes use the Shredder 9 UCI Classic GUI.

2. What Chessbase UCI dll version should I be using?
     2A. Any thing to watch out for?

3. How do I set the Hash Tables the way I like (between 64Mb and 512Mb,
depending on my goals)?

4. Do I have to modify a text file to change the Hash Table size?
     4A. How can I change the Hash Table default size & save it?

5. Can I change the HT size from within the Chessbase GUI?

6. If so, do I have to do that every time I use the engine, or will the setting
remain unchanged, if I change engines and return, or if I shutdown the GUI and
later reopen Chessbase8 GUI?

Thanks in advance for any info and tips,
--Steve
