What happens when coordinated pieces occupy weak squares?

Recently, our guest coach IM Boroljub Zlatanovic published a video lesson for you on “Weak Squares”. In that lesson, Boroljub taught you how to occupy weak squares with your pieces and create an attack against them. If you missed it, you can watch that lesson here.
IM Boroljub ZlatanovicContinuing with that instructive lesson, Boroljub has prepared another lesson for you on a similar topic – this time, answering the question “What happens when coordinated pieces occupy weak squares?

The above question can be metaphorically related to the saying “adding fuel to the fire”. :) Yes, when your pieces are coordinated, occupy the weak squares and you create an attack against these squares, you have “won” already!

Well, it’s easy to say so… but you can learn HOW to do that in reality by watching the game played by IM Boroljub Zlatanovic below:

Mickovic, Slavisa (2132) – Zlatanovic, Boroljub (2371) [A40]

1.d4 g6 2.Nf3 Bg7 3.Bf4 d6 Simply, d6+Nd7+e5 is a very solid method against the so-called “London system”. 4.c3 Nd7 5.e3 e5 6.dxe5?

After exchanging on White’s queenside, expanding is simply impossible, so… White stays without any real plan. Soon White will face serious problems. 6…dxe5 7.Bg5 Bf6 [7…f6 8.Bh4 Nh6 is another plan, based on keeping Bh4 out of play.

Nh6 is going to d6 and Bg7 to h6 or f8 with good prospects] 8.Bxf6 Ngxf6 9.Bc4 Qe7 10.0–0 0–0 11.a4?… another mistake!

Advancing pawn (even if possible) will miss its mark! 11…a5! [11…e4! 12.Nd4 c5 13.Nb5 Ne5…

was even better, but at that moment Black already had contemplated transferring the game to a favourable and comfortable endgame] 12.Nbd2 Nb6 13.Be2 [13.Ba2? Bd7! 14.Bb3 (14.b3 Bc6µ) 14…Bc6µ] 13…Rd8 14.Qc2 Bf5 with the idea of provoking advancing pawns and fixing some of them on light squares.

15.e4 Bg4 16.h3 Bxf3 17.Nxf3 Rd7 18.Rfd1 with the idea of reducing material; but after exchanging rooks, White will be far from equality.

Of course, 31…Na4 looks natural, but Black’s chances are not on the queenside. The c3-pawn is not a weakness, and White can even play c4 at some moment, thereby reducing material. Black wants to transfer Nc5 to the kingside!

32.Kh2 [32.bxc5 Qxc5+ 33.Kh2 Qxa3–+] 32…Ne6 33.Nb1 Nh5–+ Black is winning. Simply by placing pieces on comfortable squares on the kingside, Black will create a decisive attacking set-up. 34.Bf1 Qh4 35.Qd2 Ng5 36.Qe3 Qg3+ 37.Kh1 Nf4 38.Nd2 f6‡ A very funny and instructive position! White is paralysed!
