Three Golden Rules

According the the 'Steps' training program, the initial understanding of chess openings can be boiled down the 3 'Golden Rules'. They are:
1. Pawn in the centre
2. Pieces out
3. King to safety

With at least one of my coaching groups, this advice has proved useful enough, with their games starting to look like 'real chess' (according to a colleague!) And rather than tie them up with too many middlegame concepts, I've suggested that they go looking for checkmates, once their pieces are in the field.
Of course the success and failure of plans like these depends upon your opponents move, but punishing mistakes is part of the game. An example of this is in the following game, where Black ignored rules 2 & 3 and quickly ran into trouble.
