Scotch Gambit
The scotch Gambit (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4) has been my major weapon against 1...e5. Theoretically, Black doesn't have a lot of problems after either 4...Nf6 (heading for the Two Knights or Max Lange) or 4...Bc5. However, sometimes even good players respond in a stereotypical manner and get into trouble.

1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Nf6 5.0-0 d5?!Out of place here, since White can put immediate pressure on the e-file.6.exd5 Nxd5 7.Re1+ Be7 8.Nxd4 Kf8I think he was planning to play 8...0-0, but noticed the trap in time: 9.Bxd5 Qxd5 (9...Nxd4 10.Qxd4 c6 11.Qe4) 10.Nxc6 and White wins a piece, or more if Black tries 10...Qxd1 11.Nxe7+. I've caught more than one person with this one.9.Nc3 Nxc3 10.bxc3 Na5?Pretty bad. I guess he was trying to chase the bishop off the diagonal so he could play ...f6 and ...Kf7. Being a nice guy, I try to help him play the latter move.11.Bxf7! c511...Kxf7 12.Qh5+ is a long fork.12.Ne6+ Bxe6 13.Bxe6 Qxd1 14.Rxd1 This is not easy for Black, as he isn't going to be able to develop his KR for some time. But he just collapses completely.14...Rd8 15.Be3 b6 16.Rxd8+ Bxd8 17.Rd1 Ke7 18.Bh3 Nc6 19.Rd7+ Kf8?No better is 19...Kf6? 20.Rd6+. But 19...Ke8 might have given him a ghost of a chance.20.Rd6 1-0
