Nimzowitsch Defense: Kennedy Variation, Bielefelder Gambit
Overview
Nimzowitsch Defense: Kennedy Variation, Bielefelder Gambit is a gambit, classified under ECO code B00 within the Semi-Open Games family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.
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.
Play reaches this position via 1. e4 Nc6 2. d4 e5 3. dxe5 Bc5, after 6 plies of opening development.
It is a variation of Nimzowitsch Defense: Kennedy Variation, which itself descends from the root opening King's Pawn Game.
