Here is a game from the 61st Russian Championship, GM Tomashevsky - GM Morozevich with full annotations and commentary:
This game is a good example of overcoming the "Rating Inferiority Complex". Many times players will be intimidated by the opponent's higher rating and get shaken and lose their game plan and eventually lose the game. But here GM Tomashevsky played very consistently and did not get shaken by his much higher rated opponent. If you are confident in your chess ability and try to always find the best moves in each position then the sky is the limit on the amount of success that you can achieve.
