I would say "Both". The problem I had with the game was 4.d4- You just gave up a pawn for nothing... through good play you got it back.
What do you think?
It's true I did give up the pawn, but after putting pressure on the queen I was able to take his knight for free.

Well first off its clear to see he was a bad player, and when a game has come to the point of you winning his queen many moves are good moves ^^)
How did I play? Was he just a bad player, or did I play the right moves?
