# Austrian Defense

The Austrian chess players Hans Haberditz (c. 1901–57), Hans Müller (1896–1971), and GM Ernst Grünfeld studied this defense, which was initially introduced by Italian chess player Alessandro Salvio in 1604. Black creates a lot of tension and aims to disrupt White's center and prevent White from seizing the initiative by mirroring White's moves. Typically, this defense is relatively is prone to equalize quickly, however black might seek to add a little complexity to the position:

### White's responses

White will probably reply with one of the following options:

• 3. cxd5 - The classical main line in the Austrian Defense.
• 3. dxc5 - Exchanging a central pawn for a flank pawn.
• 3. Nf3 - Inviting a transposition to the Tarrasch Defense.
• 3. Nc3 - Increasing the pressure at the center.
