One of the biggest beginner mistakes is to only think about their own move.
In chess, two people always play. And every time your opponent moves, something changes.
If you don't look at what your opponent is threatening, you will play "blindly."
1️⃣ Every move changes the board
When your opponent moves a piece, you should immediately ask yourself:
- What squares does it now control?
- Which of my pieces is it attacking?
- Is there a direct threat?
Many pieces are lost not because of a brilliant bad move by the opponent, but because a simple threat was overlooked.
2️⃣ The habit that changes your level
🧠 Golden rule after each opponent's move
- Look at the piece that just moved.
- Follow its line of attack.
- Detect which of your pieces is in danger.
You don't need to calculate 10 moves. You just need to detect immediate threats.
In 80% of beginner games, serious mistakes are due to not looking at the opponent's last move.
3️⃣ Practical example

⚠️ Is the queen safe?
The black queen has just moved. It looks active and strong.
But if we look closely, the white knight can capture it.
One oversight and the queen disappears from the board.
Before moving a powerful piece like the queen, you should always check: is it defended? Can it be captured?
The mental pause prevents serious mistakes.
If it were your opponent's turn to move now, which of your pieces could they capture?
Before thinking about your plan, first neutralize the threat.
Defend first. Attack later.
4️⃣ Mini-training exercise
- Play a slow game (minimum 10 minutes).
- After each opponent's move, pause for 3 seconds.
- Don't move until you have identified at least one threat.
This simple habit drastically reduces serious mistakes.
✅ Clear summary
- Don't just think about your own plan.
- After each opponent's move, look for threats.
- Neutralize first, attack later.
Looking at your opponent's last move is the first step to stop playing randomly.
