What is the most important/most studied single game of Chess?

Fischer v Spassky

the genius vs the computer

Given the possible combinations, I don’t think any single game can be considered the most important. but if any can, Fischer probably had something to do with it.

At the moment Im looking in to Fischer vs William G. Addison in fritz 12 to see what I can learn, but Im probably getting way ahead of my self.

Also, not really an “important game” but i found the Magnus Carlsen vs the world game quite interesting, even if it was a bit of a gimmick/show.

I don’t think there is a single chess game but rather quite a few great chess games. This one was one of my favorites, a famous game I was able to review on my Chessmaster computer game. It was called the “Evergreen Game” played back in 1852 between Adolf Anderssen vs Jean Dufresne. I personally felt this game (though not a long one movewise) was one of the greatest as far as tactical skills go because if Anderssen didn’t get a check on several straight moves he would have been mated himself. http://en.wikipedia.org/wiki/Evergreen_game

If the chess world had to single out one game as the most studied, it’s Morphy vs. Allies, Paris opera house 1858.

Born in 1837, Paul Morphy was recognized as the first great chess genius. After he demonstrated that he could beat everyone in his hometown club in New Orleans, the First American Chess Congress was organized in 1857, partly to discover how the young Morphy would fare against the best players in the country. Morphy won that tournament handily, and then the only remaining question was whether he could beat the best players in Europe. So Morphy sailed over the Atlantic, and since he was a well-bred, polite young fellow with an incredible gift, the royals and chess officials in London and Paris loved him, taking him to all the best places.

The story goes that the Duke of Brunswick and Count Isouard de Vauvenargue took Morphy to the Paris opera to see The Barber of Seville, and shortly before the show began, the Duke pulled out a pocket set and asked for a game. Morphy said no, there isn’t time, and we’re out for a party, yo. But the Duke insisted, and Morphy said OK, let’s make it fast.

The 17-move gem goes down in history for its exceptional brilliance, and also because every move leading to the neat finish means something. One of the hallmarks of a great game of chess is that its moves can be tied together by positional logic — not only is Morphy-Allies bound by three or four discrete positional threads, each thread is instructive. A decent chess educator will probably make Morphy-Allies the first game that a promising student must memorize and understand, because its underlying lessons are the foundation for many time-tested principles.

The Kasparov-Deep Blue games were nothing special in terms of chess, but were historic in terms of chess software development.
