There are many well-annotated games collections. Some books that fit your description would be John Nunn's Understanding Chess Move by Move, Burgess/Nunn/Emms' The World Greatest Chess Games, Paul Keres' Road to the Top and Quest for Perfection, Igor Stohl's Instructive Modern Chess Masterpieces, Nunn's Grandmaster Chess Move by Move, and Ivan Sokolov's Winning Chess Middlegames, arranged roughly in ascending order based on the level of the target audience.
These are all excellent games collections that have deep annotation which are designed to be instructive, and you could probably could not go wrong with any of them, but the last three are probably most suitable for someone rated at least 1800.
The World's Greatest Chess Games is probably the best deal in terms of bang for your buck. There is a pretty extensive chess education available in this 700-page paperback, all for about $11.
What book of a Grandmaster's games collection has very instructive and numerous annotations of each game, as well as being a book that covers a large base of subjects?
Hopefully the book isn't too outdated either. I look forward to seeing your opinions and reviews. Thanks.
