# Game 2, with KW's additional Comments, Attempting to Help GW Understand Control of the Center[June 6th 2011]

3. ... Nf6
Immediately attacking the hole on e4; Black begins to concentrate his attack on White's light squares; Note how in the first half of this game, most of the Black pawns and pieces attack the light squares.

(GW, June 5th) I notice this is in contrast to White's Pawn occupation of the dark squares. So, is it a good plan to occupy and control the squares of the opposite color to how your opponent develops? ...

(KW, June 6th) Yes. Strategically, this can win many games. If in doubt what to do between 2 good moves, increase your control of your opponent's weak squares.

(GW, June 5th) Secondly, at which point - or should I say, which characteristic(s) of White's position? - did you determine that you should focus your development on attacking White's light squares?

(KW, June 6th) Right here when White made the last move. As I mentioned, I saw the Backward e3 Pawn, the hole on e4, the Pawn Chain being weakened from its base on f2, and the fact that I could take advantage of a number of weaknesses by a DEVELOPING move Nf6. It was almost a "no brainer" for me.

4. g3
Further weakening the light squares.

4. ... Bg4
Developing his Bishop outside the ensuing pawn chain and attacking the Queen. Black makes this move because his Bishop is protected by the Knight, and the most logical piece White should move is the Bishop on f1. Black would like to exchange his Bishop with White, to remove the White Bishop responsible for the light squares and further take control of those light squares.

(GW, June 5th) This query covers White's sixth move (6. h3), when you state "... this (6. h3) is one of the desired goals for the move Bg4". You must enter into Bg4 knowing there's a high probability you'll only have to retract the Bishop, due to White's h-pawn attack.

(KW, June 6th) Actually, because of the advantage of the Weak Square Complex, my though was to exchange for the White Bishop, as that is THE major defender of the Weak Square Complex. If it were removed, the Holes would become true Holes (as in the quote you use above from H&M-S).

(GW, June 5th) I've seen this situation played by White (Yasser Seirawan), in his King's Indian openings, where his Queen Bishop goes to g5, albeit with the Knight pin ready to occur, with Black's Knight already on f6. What typically happens then is Black advances his h-pawn to attack the White Bishop. White (Seirawan) is then seen to drop his Pawn to h4, providing the pin against the Queen hasn't been ruled out (e.g. Black's King Bishop to e7), otherwise he returns his h-pawn-attacked Bishop back down to e3.
