Vienna Game, Falkbeer Defence
Black has defended his extra pawn, but by doing so he left his Nd6 in a very delicate position, since it is the only piece preventing the mate in f7. White can exploit this weakness attacking it with


 * /6. Nb5/,

a powerful move which is the natural prosecution of the sharp situation originated by Black's choices. This move continues the path towards the Frankenstein-Dracula variation.

If White does not like to meet his opponent on this terrain, he may enter into a sideline, Adams' Gambit (named after Weaver Adams), by playing


 * /6. d4/,

letting Black keep a material advantage, compensated by his cramped position.
