Last week's show was a Nimzo-Indian that saw White's creative attacking play break through Black's attempts at a blockade; this time, the Nimzo-Indian blockade holds firm. It's game five of the 1972 Spassky-Fischer match and this game, won by Fischer, tied it up at 2.5-2.5. The game was cut short by a blunder, but even before that moment Fischer's deep strategy had proven effective, and at best White would have had to grovel for a draw.
The game is a nice complement to last week's show, and for those of you unfamiliar with the game and the blockading ideas therein, it will be a useful brick in the edifice of your chess knowledge. The show is here and it's free (free registration required if you're new to the site), and will be available on-demand for the next month or so.
