Game 3, KW's Major Digression,
7 Patterns You MUST KNOW for
Control of a Square

[Pattern #7]


(KW, June 25th) My advice to you is Know The Following 7 Patterns

Knowing When You Control A Square
- PATTERN #7 -

The move on a single ply can change the
evaluation of Control of that square,
or the Center. Evaluate all moves!

You need to take the element of Time, Initiative, and Tempo into account as you evaluate a square.

In diagram 3-8a (Pattern 6), what else can Black move? The only other possible move would be to move the Knight on c6 instead of capturing. Always check all moves before making a final evaluation of Control!

Let's look at the options:

17. d5 Nd8 (diagram 3-9a):

Diagram 3-9a
After 17. d5 Nc6.
White still Controls d5.

This move disconnects the Rooks and prevents the Rook on a8 from moving to d8, but has the advantage of protecting e6 and b7, and pinning the d5 pawn. At the same time, the Knight is close to possible future Kingside activities.

  1. 18. dxe6 Bxg2 19. Kxg2 and White still controls d5 with the c4 pawn.

  2. 18. e4 (Better, gaining an Advanced Salient and giving Black the dilemna of exchanging for a loss, or moving e5 and occupying but sharing control of e5 and seceeding control of d5, while at the same time making his Bad Bishop worse, while making his Good Bishop Bad as well). The Pawn cannot be taken by the Knight. A Kingside attack is imminent. White can follow up with f3 or f4 (as needed), Nbd2, Bc1, etc. White has gained Control of the Center.

17. d5 Na5 (diagram 3-9b):

After 17. d5 Na5.
Black's Position is worse.
  1. 18. e4 Nxb3?! 19. axb3 and Black now is being threatened on both sides of the board with a Half-Open a file attacking a Backward Pawn.

  2. 18. e4 and anything else gives White Control of d5.

17. d5 Ne5 (Diagram 3-9c):

KW's Major Digression, Pattern 7, Diagram 3-9c
Diagram 3-9c
After 17. d5 Ne5.
Black takes Occupation of e5 with threats.
Everywhere.
  1. 18. ...Ne5 19. Qe1-d2 (defending Nd3 but once again preventing our Nb1 from moving) e6xd5 20. c4xd5 a7-a5 21. f2-f4 Ne5-g4. This is not a position I would like to be in.

  2. 18. ...Ne5 19. Bxe5 Bxe5. Now our Rook has nowhere to go to. We have lost Control of e5.

This whole line shows how a single move can change the evaluation of a square, and the entire game. This demonstrates this pattern of action. Check every move! Conclusion: It is too early to move d5, as it removes protection needed on e5. Check other moves.
