Chess Opening Theory/1. e4/1...e5/2. Qh5/2...Nc6

=Parham Attack=

2...Nc6
A logical move defending the e5 pawn. Black knight could later move to d4 and threaten Nxc2+ and Nxa1, however Black can't be too hasty as White's Queen is aggressively placed.

White has only one sensible move of 3. Bc4 in view of Black's potentially in playing Nf6 to nudge the Queen away. However in the exhibition game with tennis player Boris Becker vs Garry Kasparov, Becker played 3. Qf3, a move then Kasparov showed led to the better position for Black.
