The tournament is well-spaced for ostensibly highest quality before computer days and this takes all
summer. Still on game 5 of 20.July.1972, http://www.chessgames.com/perl/chessgame?gid=1044723, it is the second Nimzo-Indian so
far, and experts credit frankly the win to Spassky's blunder in this very
last move 27. The annotations put two question marks '??'. Namely, 27
Qc2 Bxa4. No more moves and 0-1, series tied at 2.5-2.5. What should
Spassky play rather than Qc2 for the game to proceed normally, about equal in position as it is certainly in material? The Qc2 is not a move even for the local club. Was Fischer still rattling Spassky? The next
game is not til Monday.
