Let's keep commenting on this and keep it up front, instead of being buried by new material. It is so good. People can find many of their favorite players here.

Bogoljubov vs Alekhine, 1922 Amazing string of sacrifices.

Kasparov vs Topalov 99 for me. I think one has to have viewed Kasparov's annotations to understand why!
And thank god Andersson's damn "immortal game" didn't make the list for once!

Check out: Milman v Fang from the list above... I thought "two players I've never heard of: must be a good game." I wasn't disappointed -- the mating combination at the end is pure magic.

The "Peruvian Immortal" is bogus -- the guy playing Black couldn't see a textbook tactic staring him in the face. This game does not even deserve to be called "good", since the opposition was substandard.
Sorry to rain on your parade, but I can't support that game.
I don't think the game deserves to be anywhere near top either, but to say that a guy isn't a good player for missing a double Rook sac followed by a Queen sac is pretty ludicrus! lol

Double B sac,King hunt and an X-ray mate.
Nimzowitsch vs Tarrasch, 1914
Always has been one of my favorites...I was nice to see Nimzo outdone by his own style of play.

The double rook sac is merely a setup to the mating combination by deflecting the queen -- it is not very deep or difficult to see. The game is amateurish, and nothing to be particularly proud of.
Actually looking at it again I think you're probably right, even I would have probably spotted that..

Tal vs Keres (who beated him 3-1)
What's so great about that game (Tal-Keres)? I mean, it isn't bad, but I wouldn't put it even neear the top 50 I've seen.

I don't remember the players or where it was played or what year. But, I vaguely remember seeing a game where at least both queens were hanging and I think a rook for each side as well and none of them could be taken and then (if I remember correctly) white sacs a knight on the kingside.
Isn't my vagueness compelling.
Anyone want to venture a guess what game this was?

Nimzowitsch vs Tarrasch, 1914 Fun to play thru
Probably this game was not played... Who know? In Dziennik Poznanski and another polish newspapers nothing about this game. Look at :

Some time ago I've try look this game in the polish newspapers but without results . Great game, great Wojciechowski
