I played a USCF game tonight against an opponent rated about 200 points lower than me. I hate these games. They are trap games. It's going to be tough, I know my opponent will make inaccurate moves that are hard to disprove. So I was pleased to put this game in the computer after the fact and find that my position got slightly better with each and every move. Logical, patient chess that concluded with a nice king and pawn endgame.

Nicely played!  White did fairly well, too, after losing the pawn in the exchanges.  He could have put up better resistance by not advancing all his Kingside pawns so quickly.  This made it easier for you to trade off - first the Rooks and then the pawns on that side.  But good execution on your part.
