Old Indian Defence
MICOS Opening Group E09.OI – Old Indian Defence begins with 1.d4 Nf6 2.c4 d6. Black establishes a solid and flexible position, supporting the e5-square and preparing to challenge White’s centre without immediately committing to a more direct confrontation. The setup allows Black to develop naturally while maintaining options for the central pawn structure.
The Old Indian Defence often leads to strategically complex positions where careful manoeuvring, central pawn breaks and piece coordination are important. Black generally accepts less space in the early stages while preparing opportunities to challenge White’s centre and generate counterplay as the position develops.
