@PhilippeZ94,

1. Qxd4!!

a) 1...Nxd4, 2. Nf6+ Kf8, 3. Bh6#

b) 1...O-O, 2. Nf6+ Kh8, 3. Ng4+! (discovered check) Nxd4, 4. Bf6+ Kg8, 5. Nh6#

c) 1...O-O, 2. Nf6+ Kg7, 3. Nh5+! (double check) Kg8, 4. Qg7#

1. Qxd4!! O-O, 2. Nf6+ Kh8, 3. Nh5+? (crucial mistake because of 3...Nxd4!) The correct move is 3. Ng4+! (discovered check). See below:

b) 1...O-O, 2. Nf6+ Kh8, 3. Ng4+! (discovered check) Nxd4, 4. Bf6+ Kg8, 5. Nh6#

c) 1...O-O, 2. Nf6+ Kg7, 3. Nh5+! (double check) Kg8, 4. Qg7#

Good coverage of the 1...O-O variation, Mr. Montalvo, but there's also this attractive mate as a sub-variation of variation (b). If after 3.Ng4+! Black tries 3... f6 there follows the **Double Bishop Mate** 4. Qxf6+ Rxf6 5. Bxf6#.
