Weak Pawns As Targets
Seirawan Strategy Example #3

Winning Chess Strategies, Diagram 86, p141

This example focuses on the "Minority Attack" ... On the board, below, look at the Queenside and you'll see Black has a Pawn Majority of four (a7, b7, c6, d5), versus White's 3-Pawn Minority (a4, b4, d4).

But, it's even worse for White, as his trio of Pawns (on the Queenside) are split into two Pawn Islands:

* This Pawn is much stronger as it's in a Pawn Island that's connected all the way to White's h3-Pawn, on the Kingside.

Anyway, the focus of this example is on White's 2-Pawn Island (a4 & b4). This Pawn Minority is going to be used to attack Black's Pawns up the board. This is the "Minority Attack" ...
