Evans-Opsahl, Dubrovnik 1952

I'd guess that this is probably Evans's best-known game.  Nothing flashy here, but I don't know of a better introduction to the minority attack in the Queen's Gambit Declined.  You'll find beginner-friendly annotations of this game by Evans himself in Chess Catechism and by Irving Chernev in The Most Instructive Games of Chess Ever Played.
