Shestostani defence
The Shestostani Defence (also known as the Shesto–Yakub Defence) is a rare and unconventional chess opening for White, characterized by the early center pawn move e3 followed by Nf3, then d3 and Nc3, finalized by the moves Bd2 and Be2. A typical move order is 1. e3 g6 2. d3 3. Nf3 4. Nc3 5. Be2 6. Bd2, although other sequences are possible. It is considered a hypermodern and provocative system where White deliberately spends a tempo on a defensive move to limit Black's options and prepare a flexible, potentially fortified center.
