From an earlier post of mine.
13.dxe5 Be6 14.0-0+ Kg8 is probably the critical line after 9.Qe4. I think chances are roughly equal here, as Black's h8-rook is shut out of play and White has two pawns and a strong centre in return for the piece. The line 12.Bf4 Kf7 13.Bxe5 Be6 14.Qf3+ Kg8! is similar, though perhaps a slightly improved version for Black, e.g. 15.Ne4 Qh4 (15...h5!? 16.0-0 h4 17.h3) 16.Bd3 b5.
After putting it into Fritz for 60 (!) hours, this is it's best line:
