Capturing the piece with 7. exf6 is both positionally desirable (threatening to ruin Black's kingside pawns) and tactically forced. Most other moves are punished by a combination of ...Bb4+ and ...Ne4, threatening a second piece. After 7. exd6? Qxd6 Black has the same number of pieces out as White (and two extra pawns), nor does White have any way in after 7. Bb5+? Nd7 (8.Qxd5?? c6).
