I'm no expert, but...
I see in Game 3497002 you moved Kf3g5, threatening Kxf7 on your next move. I'd be wary about playing something like this against a 1500 player: players of that level have likely fallen for that trick some time before and have strategies to deal with it. Ultimately, this resulted in his queen taking your knight on black's 6th move, and then you were behind in material for the rest of the game and were set on the defensive when he threatened an exchange of queens.
Looking over the final position, I wonder if black didn't accept a draw prematurely, if he was willing to give up on the pawn on a4 and set about eliminating your pawn on the g and h files. For what it's worth, I'd suggest concentrating on working on a solid opening that limits your opponent's oppurtunity to get ahead on material early in the game.
Of course, I'm hovering around a mere 1300, so what do I know?
