Vienna Game, Falkbeer Defence
The position is imbalanced; Black is ahead by a pawn but behind in development. In searching for his next move he may choose two radically different developments: with


 * /5...Nc6/,

an apparently strength-cementing move, he enters into an extremely tactical opening, the so-called Frankenstein-Dracula variation, leading to a forced exchange sacrifice and a highly sharp position. On the contrary, with


 * /5...Be7/

he opts for a quiet continuation.
