NEW: The Vienna Variation - a reliable and ambitious weapon against 1.d4

The Vienna Variation is a particular and independent system of the Queen’s Gambit. It arises after 1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.Nc3 dxc4, when black’s capture on move 4 is strongly reminiscent of the Queen’s Gambit Accepted. But the Vienna Variation is also inspired by Nimzo-Indian structures while keeping its own character. The main variations usually lead to asymmetrical pawn structures, where Black can hope to get a fighting game.
