Here is one old game that I've played 6 years ago... it featured a dubious opening surprise by my oponent, followed by an endgame in which I've found a very exciting dynamic continuation. In the long struggle that followed, I miscalculated one mini-plan and lost the advantage, winding up worse. My oponent returned the favor, and as tables turned again, I was suddenly winning again and I followed through.
We played Caro-Kann and I had the Black pieces. I've learned a lot from playing this game and I hope that you'll find it interesting, too. Enjoy.
