Today I was playing chess against somebody at my internship company. He went all-out attack in the begin and I was only defending. He actually made some mistakes and lost his queen, rook and bishop. I won in the end fairly easy. We had a discussion afterwards about the 'all-out attack strategy'.

Is it a good thing to go all out attack or should you attack slowly? What is the best way or is it different each player? I'm not really good and the other is just as 'good' as I am.
