4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.O-O
Or 8.Qd5+ followed by 9.O-O as in Wall,B - Guest344942, PlayChess.com, 2013 (1-0, 20).
8...Nf6 was seen in a number of previous games, for example: Jerome,A - Shinkman,W, Iowa, 1876, (1/2 - 1/2, 42); perrypawnpusher - JoseSoza, Chess.com, 2012 (0-1, 34); Wall,B - Guest903719, PlayChess.com, 2013 (1-0, 47); and Wall,B - Guest1561957, PlayChess.com, 2014 (1-0, 25).
9.f4 Nc6 10.Qc3 Nf6 11.f5 Bd7 12.Qb3+ Kf8 13.Re1 Nd4 14.Qd3 c5
15.Bf4 Bb5 16.Qd1 Qb6 17.c3 Ba4
White can just take the Bishop. What am I missing? (If Black is planning 18...Qxb2 it would be well met by the obvious 19.Nd2.)
18.Qxa4 Nc6 19.Bxd6+ Kf7 20.Qc4+ Black resigned
