Here is another "smothered checkmate". It is interesting that it is the computer program that falls victim to the Queen sacrifice and mate.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O Nf6 5.Bxf7+
Transposing to a "modern" (vs "classical") version of the Jerome Gambit: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6, etc. The Database has 1,065 games with this position. White scores 41%.
Now White decides to go "classical" after all. It is as if the game started 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 and then continued 6.0-0 Nf6 7.d4 (or 6.d4 Nf6 7.0-0). If LuigiBot has a "book" it is likely it is out of it.
6...Nxe5 7.d4 Re8
Black sees no reason to retreat a piece from the d-pawn's attack, as White will win one, anyway. So, he develops.
8.dxc5 d5 9.Bg5 dxe4 10.Nc3 Bg4 11.Qe1 Qd4
Black is certainly active and better. The game still has to be won, however.
12.Bxf6 Kxf6 13.Nxe4+ Kf7 14.c3 Qd5 15.Ng5+ Kg8 16.Qc1 Qxc5
Now Black's King is safe, and there is still the matter of the extra piece. What's to worry? Well, for starters, humans can be pretty tricky...
17.h3 Nd3 18.Qc2 Be2
The computer can not see far enough ahead to avoid the Queen sacrifice.
19.Qb3+ Kh8 20.Nf7+ Kg8 21.Nh6+ Kh8 22.Qg8+ Rxg8 23.Nf7 checkmate
This is not the first time that LuigiBot has been bested by the Jerome Gambit. See "Poor, Poor Computer" for example.
