pawn structure


Nice find! Regarding the initial question two 'rules' come to mind:
- A pawn chain is best attacked at its root. By this you don't get a bad pawn.
- In positions with opposite castlig you attack the enemy King with your pawns to open lines. Otharwise you tend to attack with your pieces.
So the two first diagrams shows complex but probably equal and solid positions, where one part is attacking at the queen side and the other is trying to play the f-pawn. The third is showing a very sharp position, where boths players attack the root of the opponents pawnchain, while the fourth position probably will be a positional fight over the whole board.
With the little chess experience i've had, I've realized that pretty early on in the game after the first grab for the center, each player has to make some pretty critical choices. One of those is, "which way do I want to swing my pawn chain." Following are diagrams of four ways to advance a pawn chain. I'm pretty curious if there is a rule that relates king position with pawn structure. Do you want to anchor your pawns near your king, or away from him? Could someone with some chess experience please help me here, because I've had mixed success with each, and some advice on which to enter would be nice. In the following diagrams I'll only show castled kings and pawns, and just imagine where the other pieces might lie. Is this entirely a "what if" deal? Does the placement of other peices really determine the usefullness of each? If 6 moves in your opponent has 3 pieces in front of your castled king, do you want to open up towards your king? I know that a lot of pawn trading goes on, and these diagrams wouldn't arrise, but any general rules on pan advance will be helpful. In any replies, just call them diagrams 1 through 4.
