I'm looking for continuations after 1.e4 e5 2.Nf3 Nc6 3.Bb5 Bc5 4.O-O Qf6, but am having trouble finding them.  A master acquaintance plays it, and it works awfully well for him.  Typically, he tries to post a knight on f4.  I've tried lines with 5.c3 Ne7 6.Re1 h6 7.d4 exd4 8.e5 Qg6 9.cxd4 Bb6, with little success.  I'm less than thrilled with the lines I've found involving Bg5 and Bxe7 (i.e., taking the e7-knight).  Does anyone have any suggestions?

different...don't think I will try it, though.
