Black is still up two pieces and a pawn, but the knight on e4 is toast. With
 * 9. Qxe4 White can capture it immediately, or with
 * 9. Re1 White can take advantage of the fact that it's not going anywhere, due to the threat of Bg5+ picking up the Black queen.

White's two moves require two distinct responses from Black, but don't worry: picking the wrong one will lead to instant death, and then you can start a new game with your king back on e8.
