Garry Kasparov has overcome his desasterous blunder in the second game. In a fine anti-computer chess game he fought back, giving Fritz absolutely no chance.

a6?!
This very principled (but highly dubious) move is the novelty compared to the 2nd game.
6.c5!?
Kasparov closes the position immediately and emphasises the weakness of b6 and the dark squares on the queenside.
6...Nbd7
7.b4
a5?
A strategical mistake. May be even the losing move in a higher sense as the position is now closed and Fritz does not understand it at all.
8.b5!
Black's pawn a5 is now very weak.

A little trick – the bishop can't be taken. But the trap is much too obvious for Kasparov and only valueable time is lost. [ 14...Nb8

Fritz has no plan and plays completely random moves. It is very hard to believe that such a powerful program does not know nothing about this position. ..

the king is very secure here. This is a well known concept: the king is better placed behing its own advanced pawn wall than crushed by the enemy pawn front. True Fritz has not even begun advancing his kingside pawns.
