Petrov's Defence: Cochrane Gambit
White attacks a bit too early. Black has an effective way to block the attack: /5...d5/ (White cannot recapture the pawn without dropping a part of his offensive potential).
Other correct moves (but probably less effective) are /5...Ke8/ and /5...Be6/. In these lines, White can weaken Black position even more.
