My Pawn Went Ninja ...

Almost got another Pawn Mate with my pawn on the 6th rank and my queen breathing down black's neck.  My pawn went ninja sneaking past my enemies defenses.  I'm pretty proud of the tactics I used in this game.  Actually, I just broke 1700 on the Tactics Trainer recently and I swear that when I don't use the TT my game suffers!!!  This game REALLY shows the postives and negatives in a game with the simple move of a pawn which can really create a deadly threat or allow one.  Constructive criticism is appreciated.  Thx.
