This Knight in the corner controls just two squares.
Center occupation and center control are the two principles of chess strategy which underlay almost all popular chess openings. White would like to occupy the squares d4 and e4 with his pawns, like so:
...while Black's chess opening strategy is to occupy both d5 and e5 with his own pawns:
Both players are also trying to prevent their opponent from achieving his strategic goal (so, in most chess openings, neither player actually achieves it), but it's a good opening chess strategy for which both usually strive. The pawns can't stand alone on these squares, either; they need to be supported by other chess pieces or pawns. Remembering this will help you to understand some of the principles we're about to discuss.
1) Good chess strategy suggests you make your first move with the pawn in front of either your King or Queen
Probably the simplest of all chess opening strategies. In both cases, you'll be opening up paths which your other pieces can use to get off of the back rank:
2) Good chess strategy suggests you make good developing moves, and generally develop your Knights before your Bishops
A good developing move is one which gets a chess piece off of its starting square. This is an important chess strategy: you want to get your pieces into the game (where they can actually accomplish something, either aiding your attack or defense) as soon as you can. And the reason why you'll usually want to develop your Knights before your Bishops is because it's easier to find a good square on the chess board for your Knights:
This is an example of a "can't go wrong" Knight development; the Knights defend the pawns and control those strategically important central squares. Knowing the right spot for a Bishop often isn't so easy.
3) Good chess strategy suggests you ttry not to move the same piece twice in the opening
Don't move the same piece around aimlessly; the best chess opening strategy is to find a
