White begins the pawn minority attack
12...Bf5?
Here the exchange of the light-squared bishops is somewhat untimely and as a result White gets stable positional advantage. [ >=12...Bg4

14.b5
It appears that after 14.b5 and 15.Qb3 Black cannot do without the move c7-c6. But then a weak "Carlsbad" pawn will be created in his camp which he will always have to take special care of. Another highly important circumstance is that the g7-Bishop is in fact excluded from active play for a long while.

After the king's retreat to h8 the move 17...h6 is really necessary, for if Black decides to transfer the f8-rook to the queenside, he will have to reckon with the unpleasant threat e3-e4 with a subsequent Nf3-g5.

Beside the c6-weakness, Black has another vulnerable pawn on a7. This is the result of his ommitance of a7-a6 with the intention to avoid b4-b5.

Black resigned. This game is a classical example of the pawn minority attack when the opponent has no counterplay whatsoever. The key points to be remembered are: 1. White's b-pawn advance followed by its exchange for the opponent's c-pawn creating a weakness on c6 2. Organization of pressure on the c6-pawn by doubling rooks on the c-file. 3. Use of the c5-outpost with the manoeuvre Nc3-a4-c5. 4.Vulnerability of yet another black pawn, the one on the a-file.
