Installation instructions:

After installing, run CEZebra from Start Menu\Programs\CEZebra.

If you don't have a desktop machine

Alternatively, If you don't have a desktop machine and you wish to install it directly on the Pocket PC, you can download CAB file for your CPU separately from the installation executable.
Here are 3 of them: ARM, MIPS and SH3. (This installation method is not recommended).



Usage Instructions

CEZebra user interface is designed to be easy enough to understand without any special documentation or online help.
However, we came up with a few tips about using the advanced features:



Optional Opening Book

With CEZebra, only a THORDB opening book is shipped by default. An additional opening book for CEZebra is available for download, since 6/02/02. Here're the instructions to download & install this opening book.

PLEASE READ THIS before installing an additional opening book: First, make sure if you need it. For most Othello players, Zebra's opening engine would be fast and strong enough. Advanced Opening book should only be used by advanvced players, for Othello practice or advanced game analysis. The additional opening book is a heavy thing. You would probably need to have CEZebra installed on a storage card for this. The optional opening book (currently version 3.11) takes 8MB (!) storage space and you have to provide about 15MB of free RAM at runtime for Zebra, when using it.


Note: soon we are going to release a smaller optional book.
