Recognising the pattern # 27

In my last article we saw the demolition of the pawn structure in front of a castled king when the pawn is h6 (h3) with the help of sacrificing a piece on h6 (h3). Today we will see how to to break the king position open with a pawn lever of g4-g5.

In this position Black was completely oblivious to White’s threat and played 14…c5?, losing on the spot. Instead Black should play Nd7 though White can keep pressing with Nf3 and Rg1 due to the characteristics of pawn structure in the center.

Q: How would you proceed with white pieces?
A: In the game, White played g5 which opens up some lines by force and wins material.

15. g5 hxg5??

Now, Black can’t avoid checkmate.

Other alternatives can prolong the fight but can’t change the outcome:

If 15…Nh7 then 16. Bxg7!! Wins material.

If 15…Ne4 then 16. Nxe4 dxe4, 17.Bxe4 f6 & 18 gxf6 is winning.

16. Bxf6

Removing the key defender after which Black can’t prevent checkmate on h7 or h8.

The chances of getting success with similar attacks are very high when the position in center is stable.
