Well, I won't stop myself and post it, I'm so happy with that.
At 22th move: After I've seen a similar position in the courses, I learned that it's not horrible. There in that position, White is said to be flexible, he can make tails or forks anywhere. I imitated that.
34-35th moves: On these moves I was calculating real (or imaginary) threats from both sides. With 41-37 I've planned my next move, but wasn't totally sure if the resulting position was winning or not.
41th move: 2-16 is a weak attempt for safety, and after I lost the king I thought the game would end in a draw. Then it became like one of the "freezed out" positions in the course.
