What Is the Mortimer Trap?

The Mortimer Trap is a lesser-known yet clever idea in the Ruy López Defense, named after James Mortimer. It appears harmless at first, but when opponents play aggressively, they can quickly fall into a devastating tactical sequence, losing material or getting checkmated.

At Archer Chess Academy, we teach this trap to show how subtle moves can create powerful counterattacks.

Why Kids Should Learn the Mortimer Trap

• Promotes Patience and Timing: Teaches when to strike back in quiet positions.

• Improves Opening Knowledge: Adds depth to understanding the Ruy López.

• Fun Surprise Factor: Rarely seen in casual play, making it effective in tournaments.

Where It Happens

One version occurs after:

1. e4 e5

2. Nf3 Nc6

3. Bb5 Nf6

4. d3 Ne7!?

White often misjudges the knight retreat, leading to traps after aggressive central play. Black’s surprising knight maneuver lays the foundation for tactical counterattacks.
