2...dxe4 · Tennison gambit accepted
Black accepts the pawn and attacks White's knight.
3. Ng5 is the usual square. From here, White's knight attacks e4 and pressures f7, the most vulnerable square in Black's position. Black is objectively better, but the position is notorious for traps against an unsuspecting Black player, which Black may avoid by giving the pawn back, 3...e5.
