3...e5? Arctic Gambit
After 1. d4 d5 2. Nc3 Nf6 3. Nf3, Black plays 3...e5?, immediately challenging White's center and offering a gambit idea.
Main Line is 4. dxe5.
Downside: The main drawback of 3...e5? is that Black sacrifices a central pawn before completing development, and it unseats the Knight.
An independent line is 1. d4 d5 2. Nc3 Nf6 3. Nf3 e5? 4. dxe5 Ne4, when Black develops actively and puts pressure on White's position.
Black Also Loses by +2.0 (?).
