- A Pawn is said to be Weak if it's significantly vulnerable to attack.
- The following types are all considered to be Weak Pawns, which are ripe for targeting:
- If you own such Weak Pawns, as the five types just mentioned, then, providing enemy material cannot attack your Weak Pawn(s), their weakness is less of a problem to you.
- You can use two Pawns to create Weak enemy Pawns, by attacking a Pawn Majority that numbers three enemy Pawns:
|
[ Start ]
[ 1 ]
[ 2 ]
[ 3 ]
[ 4 ]
[ Weak Pawns ]
|
2 White Pawns Attack 3 Black Pawns
|
|
-
Typical Weak Pawn outcomes, from 2-vs-3 Pawn attacks, which both feature in the last two images of the diagram above, are:
- Doubled Pawns;
- And smaller, enemy Pawn Islands.
-
Remember: the fewer Pawns in an Island, the weaker their strength.
- Enemy positions can be quick to collapse when Weak Pawns are targeted and attacked.

- A Square is said to be Weak when it is totally undefended by Pawns and freely available for control, by either player.
- A Weak Square is also known as a Hole ... Look out for Holes, as they make for ideal spots for your Pieces.
- If you have a majority of Pawns and/or Pieces attacking any given square, then that square can be claimed as yours.
For instance, if you attack a square 3 times (with 3 separate units), while your opponent attacks the same square 2 times (with 2 separate units); if it came down to a straight fight, your superior attacking force would end up claiming that square ...
And, it's on that basis how you can determine who has control of any given square - tot-up all the squares controlled by each army and you can determine who has a territorial advantage, in any region of the board.
- On pages 146-147 of Winning Chess Strategies, Yasser Seirawan shows how Anatoly Karpov, in a game played against Walter Browne in 1972, was able to "play to create a weak square" ...
Once the weak square was "captured", Karpov wasted no time in getting all of his Pieces to it.

- On pages 155-158 of Winning Chess Strategies, Yasser Seirawan shows how entire lines of squares, rather than any individual square, can become vulnerable to enemy penetration.
Seirawan gives Diagrams 92 & 93, both on page 155, as quick examples of Lines of Weak Squares, followed by a lengthier example involving a game between Steinitz-Blackburne, London, 1876.
