Sabrewolfy vs Fritz@1300

Fritz takes me through an opening I've never seen before.  I end up choosing book moves, but pieces are quickly liquidated resulting in an endgame that is even or slightly better for black.  I make a few errors, and Fritz achieves a winning position.  Fritz blunders and allows me to draw, but I blunder back on the very next move, and the chess gods hath declared that he who makes the 2nd to the last blunder winneth.
