Nimzowitsch Defense: Kennedy Variation, Hammer Gambit
Overview
Nimzowitsch Defense: Kennedy Variation, Hammer Gambit is a sacrificial opening line filed under ECO B00 in the Semi-Open Games group. The defining idea is the early concession of material to seize the initiative and unbalance the position.
The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.
It begins with 6 plies and takes 1. e4 Nc6 2. d4 e5 3. dxe5 f6 to reach the canonical position.
In the opening tree, this line branches off from Nimzowitsch Defense: Kennedy Variation, part of the broader King's Pawn Game system.
