What if Black decides to capture e4 on move two? I pasted in a variation that may counter the center counter and stop Black's common early queen move. White is down a pawn, but perhaps can capture Black's troublesome pawn in the pasted variation? This would be a nice novelty to try.
Ah...it's not in any book moves after so many years of theory, so White would probably lose in the exchange. After my first attempt at an exchange it appears that White is behind one tempo and can't capture that pawn. Hmm...

Musikamole, it's good to be informed on such well-grounded principles, but not to adhere to them like commandments. The Center Game is fine for a beginner yet "breaks" the 2. Nf3 rule.
The Four Knights Opening is a very good beginner opening as well. I don't think it's been mentioned yet? It was the only real opening we school kids played, unbooked as we were.
goldendog - Four Knights! I forgot all about that one. Thanks! It will be fun to teach that to the school kids tomorrow, as they get confused as to how the knight moves. This variation also teaches one how to develop a bishop and castle. A fine battle can then start.
