Four Knights Game: Halloween Gambit, Plasma Variation
Overview
Four Knights Game: Halloween Gambit, Plasma Variation is a sacrificial opening line filed under ECO C47 in the Open Games group. The defining idea is the early concession of material to seize the initiative and unbalance the position.
The Open Games group covers open games — classical 1.e4 e5 openings where both sides contest the centre directly with pawns.
It is reached after 22 plies of play, with the move sequence 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Nxe5 Nxe5 5. d4 Nc6 6. d5 Ne5 7. f4 Ng6 8. e5 Ng8 9. d6 cxd6 10. exd6 Qf6 11. Nb5 Rb8.
In the opening tree, this line branches off from Four Knights Game: Halloween Gambit, part of the broader King's Pawn Game system.
