I am puzzled.
I am nobody to criticize Karpov in move 6 but this is weird to me.
6. d5! is the strategical refutation of c5 and this has been known
for a long, long time. As a general rule, every time you have a fianchetto
in b7 if you can "safely" play d5 is small victory for white. Bb7 is out
of the game and many times the bishop has to re-rout to c8 which is basically
two tempos. The secret of all this is in the word "safely". But this position
has been thouroughly tested, I have not been in touch with theory for years
but I doubt this changed (but chess has always surprises). White get a nice
position after d5, and the proof is that d5 was on fashion for a while even
without c5. Kasparov will be salivating after playing d5 here.
Anyway, Karpov has been known many times not to play the most energetic move
to avoid problems. He wins anyway so why bother with preparation from the
opponent?
Was this a slow pace game or blitz?
