This is a port to AROS of CFish, a chess engine derived from Stockfish
by rewriting its C++ code in C. It is not a complete chess program
and requires some UCI-compatible GUI in order to be used comfortably.

Porting has been made with Claude AI from Anthropic.
This newer version has an improvement only for two cosmetic changes.

Features:
- Polyglot book supported
- Syzygy tablebases supported
- Multithread
- Strong playing algorithm
- Compact size (executable is 277 Kb)

Is mandatory a good allocation stack in order to avoid engine crashes
when computing moves.
So, before executing engine launch this command from shell:

stack 512000

### Terms of use

This program is released under the GNU General Public License (GPL).
Essentially, this means that you are free to do almost exactly
what you want with the program, including distributing it among your
friends, making it available for download from your web site, selling
it (either by itself or as part of some bigger software package), or
using it as the starting point for a software project of your own.

The only real limitation is that whenever you distribute Cfish in
some way, you must always include the full source code, or a pointer
to where the source code can be found. If you make any changes to the
source code, these changes must also be made available under the GPL.
