Norwegian gambit B06 Modern Defence
4...d6 · Norwegian gambit
Black, not caring about the fact that White can win a pawn, plays d6. The main idea of this gambit is that after 5. Bxh5 gxh5 6. Qxh5 dxe5!, Black has potential traps that they could spring.
5. Bxh5 is the obvious move, winning a pawn after 5...gxh5 6. Qxh5. It seems that White is simply better. However, after 6...dxe5, White may have to navigate a pitfall of traps that Black may create.
5. exd6 is another possible reply. White declines the gambit and decides to trade pawns. After 5...Qxd6 6. Nf3, White carries on with normal development.
