I don't know if it's currently considered one of the greatest but one of my favorites is still Alekhine's brilliant Dutch Defense against Bogoljubov at Hastings in 1922.
Greatest Chess Games

The immortal king walk! I forgot about that one. Great game! Short vs Timmon (1991) is another great king walk but in that game the king marches down the board in the middle game to assist in the mate.
If Korchnoi got a lost position in the first move that wasn't theory I wouldn't rank it as the greatest game ever... Impossible to pick one greatest game but that Kasparov vs Topalov game isn't a bad candidate.
How about Steinitz against Curt von Bardeleben?

Korchnoi got a lost position after the first move that wasn't theory because karpov played a novelty and korchnoi wasn't accurate enough although the move did look accurate it basically lost by force which i thought was very cool.

Here is a brilliant game by GM Serper. Not many know this. He sacrificed all his pieces except for the queen.

I have looked at a lot of famous chess games and in this forum, I would like to discuss the greatest chess games or what you all in the chess community think is the greatest chess game ever played. In my opinion, the best chess game ever played was in the 1974 Candidates Final between Anatoly Karpov and Victor Korchnoi. The game I am referring to is game 2 of the match where Karpov was white and the game played was a Sicilian dragon where Karpov played the yugoslav attack(the sharpest line) which was unlike karpov because he would always play slow and positional chess where as korchnoi liked to play aggressive chess and this choice by karpov seemed to play into korchnoi's hands. Anyways, this game followed 18 moves of theory and then Karpov played a novelty 19. Rd3!. The following move by korchnoi ...19 R4c5? to protect against the idea of g4-g5 loses to the move, funnily enough, g4-g5!. Karpov went on to when this sharp sicilian dragon game and went on to win the match after korchnoi had only made the one mistake on his move 19, after karpov's move 19 novelty. What did you guys think about the game? Do you consider it as one of the greatest? If not, what do you guys think is the greatest game? I would just like to know your personal opinions and I'd like some more games to study.
