Chess Improvement Ideas Part 15

Pin It How to develop when the centre is closed?

With the pawns in the centre wedged against each other, it is on the flanks that break-throughs are usually made. Often the players take one flank each and then try to be first to break through. However, the rule "An attack on the flank is best answered by a counterattack in the centre" can be relevant even with a closed centre, as it may be possible to disintegrate the centre by sacrificing a piece.


White's and Black's pawns form an interlocked chain in the centre.

Ari Ziegler -- Mikael Johanson Astorp 1990


1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. O-O Nc6 8. d5 Ne7 9. Ne1


This is the common variation of the King's Indian Defence. The centre is closed so play is shifted to the flanks. Black's pieces are placed to act on the kingside. The key move is ....f5 followed by ...f4 and then g-pawn will advance to open up files towards White's king. White wants to make his key move, c5, and penetrate on the c-file with the major pieces.

9 ...Nd7 10 Nd3 f5 11 Bd2 c5

A radical way to prevent White's key move, but White now has a new way to break up Black's pawn-structure, with the advance b4. More common than the move played is 11...Nf6 12 f3 Kh8 with the idea ...Neg8 and ...Bh6.

12 Rb1 Nf6 13 f3 f4 14 g4!?



This move looks crazy at first, as you seldom want to advance the pawns in front of your own king. However, in the race to break through first , White wants to create a blockade on the kingside. the move g4 is similar to Black's ...c5, directed against opponent's natural key move.
