Which games are very instructive and worth analysing? Do you have suggestions?

Finally I found it! Beneath Nintendo computer game cartridges, books by Plato and cassette tapes, I dug out my copy of "The Mammoth book of the world's greatest chess games" by Burgess, Nunn and Emms and expanded to 125 games.

Updated in 2010 so it's pretty decent. All 125 games here are awesome starting with McDonnell Labourdonnais, Match(16) , 1834 and ending with Anand Topalov, World Championship (4), Sofia 2010.

But let's pick one that starts by saying: Magnus Carlsen, born 1990, is widely seen as a future world champion: Carlsen Kramnik, London 2009.

I was going to say, would it be enough just to track down some good books (or even find decent quality video stuff) on topics that you're interested in and look at the games that they use as examples? You'll get interesting games, a bunch of analysis from the book or video, and then be able to take it further by looking at them for yourself.
