Of the unorthodox move 5.f3 Fischer wrote, 'A passive, non-developing move which leads to nothing. White wants to gain control of d5, establishing a Maroczy bind with c4, Nc3, etc. But after going to all that trouble he can't prevent ...d5 after all.' The game continued 5...Nc6 6.c4 e6 7.Nc3 Be7 8.Be3 O-O 9.Nc2 d5!?. Here he commented, 'Reckoning that the loss of a Pawn is compensated for by superior development. 9...Re8 is sound but passive.'
Times change and chess changes with the times. Nowadays the move 5.f3 is played frequently by players at grandmaster level. Black often continues 5...e5 instead of Fischer's 5...Nc6, but 5...Nc6 6.c4 is also seen often, when the move 6...Qb6 is more fashionable than Fischer's 6...e6.
Openings are subject to shifts in fashion, but positional principles remain tried and true. The bind will always be a weapon in the arsenal of the astute chess player.
