The Old Indian Defence arises after 1.d4 d6 2.c4. ECO code: A41.

Overview

The Old Indian Defence is characterised by Black's ...d6 and ...Nf6 setup, preparing ...e5 to challenge White's centre. Unlike the King\'s Indian Defence, Black does not fianchetto the king's bishop, instead developing it to e7 or d6.

Strategic Themes & Plans

Black builds a solid but somewhat cramped position, planning the central break ...e5. The centre becomes a focal point of the struggle, with Black aiming to undermine White's d4-pawn. White should establish a strong centre with Nc3, e4, and develop pieces actively to exploit Black's passivity.
