No, Rc8 is not essential. As to being the best move (better than others), I have
little doubt, but I am not claiming Black is suddenly much better. After
Karpov's move White is stuck to passive defensive play while Black can easily
build up the pressure. That always was Karpov's greatest genius, and this is
pure Karpov.
