This game, although not a high standard, shows the advantage of developing your pieces and not making too many early pawn moves.

3...Nf6 would be Petrov's defence.

I prefer an open game where my pieces have freedom. 3...a6 gives me a chance to do that.

With 2 pieces attacking and 2 defending, this looks good to me.

This allows the Queen's Bishop out, but where is it going to go?

I'm looking to develop my pieces and get the King to safety. I have 3 pieces developed and Black has none.

Lots of pawn moves.

Attacking the Knight and threatening to Checkmate if dxe.

I don't mind removing Blacks only developed piece.

I have 3 pieces attacking d6 and Black has only two defending.
