The American Heritage® Dictionary of the English Language: Fourth Edition. 2000:
Inspired by several old chess variants, Jean-Louis Cazaux from Toulouse (France) invented this variant. The name Shako means Chess in Esperanto, `another kind of non-conformism and utopia', in the words of the inventor. The idea of this variant is to make a new game without directly disposing the large heritage of the classical game.
