Having long pondered the venerable game of chess that for over a millennia mirrored the form and progression of warfare as commonly encountered (combatants facing one another across a 'no-mans land' upon which the battle will be waged), I was provoked in the mid-1980s to wonder how it might be reformed to represent the kind of battleground upon which combat now occurs within metropolitan regions in particular (friends and foes living side-by-side with incessant sacrifice of the former required to defeat the later). The answer, as reproduced here, was formalised on 26 September 1987.
