The following game is another example of Black defending well, only to relax too early - and feel the sharpness of White's attack.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+
The Italian Four Knights Jerome Gambit.
5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 d6
9.O-O Bd7 10.f4
One of the weapons in the Jerome Gambiteer's arsenal.
10...Nc6 11.Qc4+ Be6 12.Qe2 Re8 13.f5
An annoying "Jerome pawn" move, another weapon.
13...Bc8 14.Qc4+ Kf8
15.Bg5
Ditto.
15...Ne5 16.Qb3 b6 17.Nd5
And, again.
17...Bb7
Black completes his development, and wonders "Have you got anything left?" White shows that he does.
18.Nxf6 gxf6 19.Bh6+ Ke7 20.Qe6 checkmate
Very pretty.
