Thanks Antoine.

I just received today in the mail an original Spanish copy of Gabriel Vicente Maura's 1973 3rd edition 'Mathematical Thesis for Modern Chess including the Prime Minister'!!!

I found it in a Library of Antique Books in Madrid, Spain.

Nice little book (it's only 48 pages long).

It has Gabriel Vicente Maura's 'mathematical' explanation of why the chess board needed to be increased in size to 9x9, why a new powerful piece needed to be added to the game, and why that piece needed to be a Prime Minister (Bishop + Knight).

Interesting 'mathematical' theory.

I'll digest it first, and post a summary of his theory.
