This is one of the many exciting, if flawed slugfests that took place in what may have been the most famous WCH ever played. Bobby boldly goes where no GM has ever gone before and plays the Najdorf Poisoned Pawn Variation in a WCH game only to discover that Boris is so well-prepared for his pet line he has Fischer "on the ropes" for a long time but never quite gets in the final KO as both players err in critical situations, climaxing in Spassky missing a win just 2 moves before the game ends!
Once again collating analysis and comments from several sources reveals major differences of opinion throughout the game at critical junctures with the final verdict depending on you to decide.
Halldor Petursson was a famous Icelandic caricature artist who drew 18 cartoons of the match for a local newspaper. In this one, Bobby appears to be using his mojo to keep Boris from beating him at one of several critical junctures where Boris could have knocked Bobby out for the count.
