Fighting for the line of attack

 How to conduct a game?

My idea is pretty simple. There are sitting ducks (the king and the pawns). Attack them!

In the beginning only the king is vulnerable. Put pressure on him, and chances are that something will give in. That other weaknesses, especially weak pawns are created. New weaknesses means new targets. Attack them!

The Colle approach is actually exactly so straightforward as described here.

You see how all lines of attack point in the direction of the enemy king.

The task for black is to create obstacles in the lines of attack.

Whites pride and joy is the bishop on d3. How can black neutralize it?

• a knight on f6 covers h7, which is the end of the line of attack
• a knight on e4 blocks the bishop
• a pawn on f5 blocks the diagonal
• a pawn on g6 ditto
• a pawn on c4 chases the bishop away
• a knight on b4 ditto
• a bishop on a6 threatens to exchange the bishop on d3

Black will try to make the line of attack useless, while white tries to prevent that.

The same principles work for the other bishop. White can open up the diagonal at any appropriate moment with dxc5. Usually he will not do that, though, since the bishop is doing a good supportive job.on the long diagonal. dxc5 is only appropriate when black threatens c4 (after b5, for instance) OR when there is a combination along the long diagonal. A greek gift or something like that, for instance.

You see you can judge every detail of the position by its effects on the lines of attack. Thus introducing chess logic in the game.
