How not to win a game?

Hi, I wish to share with you my analysis of some of the games I have played in this site.  The first of my analysis, is where I have played as black and there were ample opportunities for white to win, though in the end white lost.  I am hopeful that the game analysis will be insightful to many beginners and intermediate players.  The PDF titled rightfully "How not to win a game?" is available in the link My Chess Annotations.  Your comments are welcome at esnips or at My 2 Cents.  Hope you enjoy the reading.
