Overview

King's Gambit Declined: Classical Variation is a sacrificial opening line filed under ECO C30 in the Open Games group. The defining idea is the early concession of material to seize the initiative and unbalance the position.

It begins with 7 plies and takes 1. e4 e5 2. f4 Bc5 3. Nf3 d6 4. c3 to reach the canonical position.
