I suggest that black now play...

10. ...h6 11.Bh4 (white might also try 11.Bxf6 gxf6 12. exf6 Nd7!) or (12. exd6 Nd7! with equality for black in both cases) dxe5 12.fxe5 Nd5! 13.Nxd5 exd5 14.e6 (14.Bc4 Bc5 15.Bxd5 O-O is at the very least equal for black) 14. ...Bxe6 15.Rxb7 Bd6 (15.Nxe6 fxe6 16.Bd3 Be7 17.Bg6+ Kd8 18.Bxe7+ Qxe7 19.O-O b5 20.c4 Qc5+ 21. Kh1 bxc4 22.Qe1 = ) 16.Be2 O-O (16.Nxe6 will transpose) 17.Nxe6 fxe6 18.Qd4 Rf7 19.Rxf7 Kxf7 20.O-O+ Kg8 21.Qg4 Qe3+ 22.Bf2 Qe5 23.Bd4 Qxh2+ 24.Kf2 Qf4+ 25.Qxf4 Bxf4 26.Bg4 Nc6 27.Bxe6+ Kh8 28.Bxd5 Rd8 =
