Defending against Tactics
Find the only move
In this lesson you will learn
- How to spot your opponent's threat
- The four defences: move, protect, block, counterattack
- Finding the only move under pressure
- Why counterattack is often the best defence

10.1 What Is the Threat?
Every tactic you learn is also a tactic that can be played against you. After every opponent move, ask: what does this move threaten? Then choose a defence: move the attacked piece, protect it, block the attack, or create a bigger threat of your own.
- Move the attacked piece to a safe square.
- Protect it with another piece.
- Block the line of attack.
- Counterattack: make a threat that is bigger than your opponent's.
Example 10.1 · Capture the attacker
Black's knight on g3 attacks White's queen on e2 and rook on h1 at the same time.
10.fxg3! removes the forking knight. Moving the queen would lose the rook on h1. When an enemy piece makes two threats, first check whether you can simply capture it.
Example 10.2 · Counterattack
White threatens dxc6, winning the knight that is pinned by the bishop on b5.
9...a6! attacks the bishop that creates the pin. If White takes on c6, Black takes the bishop on b5, and material stays level. When you cannot defend directly, attack the piece that is attacking you.
Remember
- After every opponent move, ask: what does it threaten?
- Defend by moving, protecting, blocking or counterattacking.
- Under pressure, find the only move — calmly.
- A bigger threat is often the best defence.
