All you people are crazy. The roman army was freaking amazing, but It wouldn't stand a chance against Napoleon let alone the Modern U.S. army. What on earth makes you think Fischer could could beat superior technology and overall chess knowledge that Josh had?
A spurious argument. Bobby and Josh had the same weapons.
On the other hand Josh Waitzkin does have a black belt in martial arts so a 20 year old Josh could have beat up a 20 year old Fischer just not at the chess board.
