The Doery Defence arises after 1.d4 Nf6 2.Nf3 Ne4. ECO code: A46.

Overview

This unusual defence sees Black retreat the knight to e4 on the second move, claiming a central outpost. The knight on e4 can be difficult to dislodge without concessions.

Strategic Themes & Plans

The knight on e4 is aggressive but potentially unstable. White can challenge it with Nbd2, e3, Bd3, or c4. Black aims to maintain the outpost and develop around it. The defence is uncommon and somewhat provocative, but the centralised knight can cause practical problems.
