In this game I played Queen's Gambit Defense as black.  I am illustrating this game for the opening play in which I attacked white's knight on c3 and gained a pawn up.  I eventually lost the game after 70 moves with both sides in time pressure (35 min. game) because I lost the advantage I gained in the opening.  I am a 1500's player so this game-talk is for beginners who want to learn more about the Queens' Gambit and it's defense.  Attacking the white's knight on c3 is a common occurance for black in the Queen's Gambit.
