3...d6! — Radium Gambit Accepted: Triton Variation
Black immediately attacks the knight on e5 and attempts to regain the sacrificed pawn while developing the position.
4. Nf3 retreats the knight to safety and keeps the extra pawn for the moment.
4. Nc4 keeps the knight to safety and maintains pressure on Black's position.

The Radium Gambit Accepted: Triton Variation is characterized by 1. e4 e5 2. Nf3 Bb4 3. Nxe5 d6, with Black immediately challenging the knight instead of using 3...Qe2.
The Supposed Line Is 1. e4 e5 2. Nf3 Bb4 3. Nxe5 d6! 4. Nc4
