Lesson 20
Pawns help each other
- What you will learn
- You recognize the base and the tip of a pawn chain and attack the chain at its base.
- What you should already know
- How pawns move and capture
- What a blockade is
- Lesson 17: A knight stops the pawn
Time: about 5 minutes
Thinking questions in this lesson
You can ask yourself these thinking questions in any position. They help you find a good move.
- Which pawn move changes the position?
Step 1 of 6
Look first
After 1.e4 e6 2.d4 d5 3.e5 the white pawns on d4 and e5 stand diagonally one behind the other. In front of each stands a black pawn.
Such a diagonal line is called a pawn chain. One pawn of the chain protects the other.
Tap the white pawn of the chain that protects the other one.
Arrow keys move the focus across the squares. Enter or Space marks a square or removes the mark.

Step 2 of 6
Decide
The white chain blocks the way forward for your pawns on d5 and e6.
The white chain cramps your pawns. How do you attack it?
Arrow keys move the focus across the squares. Enter or Space selects a piece and moves it to a highlighted square. Escape cancels the selection.

Step 3 of 6
Try it
Attack the base of the white chain with a pawn.
Arrow keys move the focus across the squares. Enter or Space selects a piece and moves it to a highlighted square. Escape cancels the selection.

Step 4 of 6
Why does it work?
The base carries the whole chain. If it falls, the next pawn has no pawn protection any more, here the tip on e5.
Nimzowitsch compares the chain with a house: whoever wants to bring it down starts with the foundations and not with the decoration. Seen from White’s side, d4 is the foundation right at the back, e5 the decoration right at the front.
If you only attack the tip, the base stays and keeps supporting.
Key idea
If a pawn chain cramps you, attack it at its base, best of all with a pawn.
When does this apply?
The base is the pawn of the chain that no other chain pawn protects. If it is well protected by another pawn, you need pieces to help with the attack.
Step 5 of 6
New position, same idea
Here the white chain is longer. Only pawns with a black pawn in front of them belong to the chain.
A longer chain. Attack its base with a pawn.
Arrow keys move the focus across the squares. Enter or Space selects a piece and moves it to a highlighted square. Escape cancels the selection.

Step 6 of 6
Nimzowitsch and today
Source
Nimzowitsch calls the lowest pawn of a chain (seen from White, the one furthest back), on which all the others rest, the base. A chain, he says, is attacked first at its base, and with a pawn: after 1.e4 e6 2.d4 d5 3.e5, 3…c5 is right, by no means 3…f6. Whoever wants to blow up a building starts with the foundations and not with the ornaments. Once the base has fallen, it is the new base’s turn. The aim is to make your own cramped pawns mobile again: in his example Black finally plays …e6–e5. The texts are newly written for the course; the transfer position is based on a diagram from 9.3, with kings, pieces and further pawns added.

Today’s view (editorial note)
Today too, in this position of the French Defense, Black usually attacks with 3…c5. White then often supports the base with c2–c3. If d4 is well protected, Black later often attacks the tip with …f6 as well.
