Queen and Pawns vs. Rook and Knight

Here is a very recent ICC standard game that I played. The time control was fifteen minutes with a three second increment for each month made. Obviously Black is much better in the endgame. My opponent resigned realizing that White has too many pawns and a Queen vs. his lone rook and knight. But if I was White playing down in the endgame, I would have played on to the biter end. Only because Black can make a mistake and perhaps lose his Queen somehow. The first chessboard game is from the actual game.
