Nc6 and 7 ... c6. either of these is so effective against 7 Bd3, In keeping with his whizz-kid image, Kasparov has already qualified for the Candidates' semi-final before the other three quarter-finals have even started. He needed only 51/2 points to topple Beliavsky, litY opinion his most dangerous rival in lne entire competition, but exceeded the re- quired margin by winning game 9, when a draw would have been quite sufficient.
