1.Nf3 c5 2.b3 d5 3.c4 dxc4

    The Regina Nu Gambits all have this basic shape. White does not
    capture the pawn but chooses a developing move instead.

4.Nc3
       4.e3 Can be used here.

4...cxb3 5.e4***

5...bxa2 6.Bc4

    White has given up three pawns, but one will be regained and there is a lot of development.

6...Nd7 7.O-O Nb6 8.Bxf7+  Far too optimistic.

8...Kxf7 9.Ne5+ Ke6

    9...Ke8 10.Qh5+ g6 11.Nxg6 Nf6 12.Qh4 Rg8 13.Nxf8 Rxf8 and Black is way ahead.

10.d4 cxd4 11.Qg4+ Kxe5 12.Qf4+ Ke6 13.Qf5+ Kd6 14.Ba3+

    14.Bf4+ was considered, but that's the wrong approach!

14...Kc6
    14...Kc7 Leads to a cute mate. 15.Nb5+ Kb8 16.Qf4+ Qd6 17.Nxd6
    exd6 18.Qxd6+ Bxd6 19.Bxd6#

15.Qc5+ Kd7 16.Qb5+ Kc7

    16...Ke6 17.Qf5#

17.Qe5+ Kd7 18.Qb5+
    is a forced draw.

*** 5.e4 see Kramer's Gambit

I think 8.Bxf7+ was downright foolish. White sacs two pieces for a draw when there were at least ten moves that were better. Schiller could have ended his annotation there and shown some better lines to provide insight into the Gambit. Here are ten lines from the Toga II engine.
