It's much more instructive to analyse by yourself and with other players before asking the computer.
This way, if you make any tactical mistake, you're bound to remember them when the computer points them, because of your earlier implication.
Besides, it's also a good way to assess your ideas.
As for the game :
- 2...f5! good idea, your opponent must have felt the danger at this point 
- your reaction to his c6 move looks very good.
All in all, a good game, though I'm not sure about your e5 sacrifice, although it worked remarkably well.
After joining this site and reading the sticky threat I've changed my method.. let me know how I did :).
