Programming a mini chess in phyton: How to make a funny mini chess?->an experiment

Pico means something like "trillionth" – that is very small.
The workload for programming a "chess program"
on 64 fields is very large.

So the author decided to do a very small chess on 20 squares
to program, so to speak, as an "experiment" without special requirements.
Phyton was used as the programming language.
The aim of this project was to understand the "construction principles"
of a chess program.

The current state of knowledge of chess programming
is at | 4 + 5 |.chess only partially available.

The mini-chess variant is a specially programmed creation.

With this in mind, I wish all readers and chess lovers a lot of fun and health
