An unusual defense

This is the second of my game analysis. It is a game played online here, where black plays a courageous and an unusual defense classifed here as Carr defense. I have included an analysis of the opening and discussed the poisoned pawn in the middlegame. Hope you find them resourceful. The annotated game is available at "My Chess Annotations" (the widget to the right) and the document is titled "An unusual defense". Enjoy the game
