The Worst Tournament of My Life Game One

I had a horrible tourney this weekend. I played in a five-round swiss and had high hopes of winning the tournamet because I had easily won a tournament a few months earlier which was just slightly weaker then this one. Disaster struck in Round 1 however as I got a winning advantage. My opponent had some counterplay but all I have to do is find Rc5! and I win easily. Alas, I missed my chances to play Rc5 and my king nearly perished under the crushing attack and I lost.
