This game was an interesting example of calculation. I had thought out and calculated a line that I believed was good. However, my calculation stopped after 3 moves and then on the 4th move my opponent had a move to stop me in my tracks. Luckily for me my opponent missed the move and I ended up with a winning position. It really shows though how its best to always calculate 1 extra move (or more if you have time and the position requires it).
