Sometimes the recipient of a gambit is skeptical. Free material? Why not grab all I can get?? The gamiteer adds: It will cost you.
In the following game Black happily receives a Bishop and then a pawn. When offered a Knight, he scarcely resists the temptation.
White then shows that his "generosity" should have been taken seriously, as well.
Philidor 1792 - NN
1.e4 e5 2.Bc4 Nf6 3.Bxf7+ Kxf7 4.Nf3 Nxe4 5.Nc3
Combining Jerome Gambit ideas with the Boden-Kieseritzky Gambit!
I have only seen this once, mentioning the idea in a note in an earlier post about an earlier Philidor 1792 game, referencing Jirotka,S - Super Expert, 1990; but The Database is incomplete concerning 1.e4 e5 2.Bc4 Nf6 3.Bxf7+.
We have seen 5.Nxe5+ in a number of White's games: Philidor 1792 -guest2044, www.bereg.ru, 2013 (1-0, 45); Philidor 1792 - guest213,www.bereg.ru, 2013 (1-0, 41); Philidor 1792 - guest564, www.bereg.ru, 2013 (1-0, 56); and Philidor 1792 - guest45, www.bereg.ru, 2013 (1-0, 28).
5...Nxc3 6.dxc3 d6
A typical mistake against the B-K.
7.Nxe5+ Ke6 8.0-0 Kxe5
I was not being frivolous, thinks White, believe me.
9.Qh5+ Ke6 10.Re1+ Kd7 11.Bg5 Black resigned
