4. Qe2
White threatens the black knight and sets up discoveries along the e-file that Black opened for them. Beginners often err here, but with best play by Black this is a pawn sacrifice with partial compensation.
The classic beginner's blunder of saving the knight, 4...Nf6??, allows 5. Nc6+ discovered check, winning Black's queen.
4...d6? to counter-attack White's knight allows 5. Nxf7! Kxf7 6. Qxe4++ (White is up a pawn).
4...d5? to defend the knight does not resolve the pin. 5. d3 Qe7 6. dxe4 Qxe5 7. exd5 Qxe2+ 8. Bxe2++ (White goes into an endgame up a pawn).
Black's best move is 4...Qe7, setting up a pin of their own after after 5. Qxe4. This is the Kholmov gambit: 5...d6 6. d4 dxe5 7. dxe5 Nc6+ and Black wins the piece back at the cost of the d-pawn. Black may not have complete compensation for the pawn, but it offers decent practical chances, especially at faster time controls.
