When Polgar Crushed Karpov's Caro Kan Defence

One trend that emerged in the 90s was Active Chess where each side is alotted 25 to 30 minutes to complete the entire game instead of standard 40 moves in 2 or 2 1/2 hour followed by a sudden death. Quality obviously suffers, clock forces error, but chess marches on.This is second game  out of the 8 exhibition games played between Judit Polgar and great Anatoly Karpov in 1998, In which Judit Polgar won with the score 5-3.

In this game Judit Polgar had white and she started with the move

 1.e4 c6

and we had seen Caro Kan defence on the board, one of the favourite opening of Anatoly Karpov with black.
