condemned as bad (though very interesting), but in my research this move isn't
addressed. But} (7... d6 {leaves Black with reasonable compensation and a
possible transposition to the game, without allowing White the chance missed
on move 8.}) 8. Nge2 (8. fxe5 {looks risky, but Black can't exploit the f2
square and White seems to get a large advantage after} Re8 (8... Nxe5 $2 9. d4

as the "most Nimzovichian" of Fischer's games, reminiscent of the very famous
Johner-Nimzovich game from Dresden 1926 (look it up, audience!). Black's play
here is all about blockade: he's going to seal White in, then destroy him.
Ironically, though, the computer is quite happy here with the White pieces!}
