it could be japanese chess... this does not have black and white board and pieces... it has only 1 knight bishop and rook .. but added gold and silver general and a lance...
and you can setup the pieces how you like... i think?!?

I have added a slideshow at http://www.jmrw.com/Chess/Tableau_echecs/index.htm#bas
It works under firefox. Under IE there are still some corrections to do.
Later I will play the paintings in the chronological order.
What do you think of it? What can I improve?
Thanks
